Here the priorities shift to continuous-duty thermal design, current sharing (for paralleled units), and communication control \u2014 the SP-6000 series supports RS-485\/MODBUS so charging can be monitored and scheduled by fleet management software, while its PF\u22650.99 power factor and 93% peak efficiency keep operating costs down across hundreds of daily cycles.<\/p>\n<p>For a deeper comparison of the underlying topologies and their trade-offs, see our article on the <a href=\"https:\/\/www.wehopower.com\/es\/news\/switch-mode-power-supply-advantages-disadvantages\/\" target=\"_blank\" rel=\"noopener\">advantages and disadvantages of switching power supplies<\/a>.<\/p>\n<figure id=\"attachment_7194\" aria-describedby=\"caption-attachment-7194\" style=\"width: 750px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.wehopower.com\/es\/products\/\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" class=\"wp-image-7194 size-full\" title=\"SP 3000 High Power Switching Power Supply\" src=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2024\/11\/SP-3000-High-Power-Switching-Power-Supply.png?quality=85&strip=all\" alt=\"SP 3000 High Power Switching Power Supply\" width=\"750\" height=\"750\" srcset=\"https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2024\/11\/SP-3000-High-Power-Switching-Power-Supply.png?quality=85&strip=all 750w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2024\/11\/SP-3000-High-Power-Switching-Power-Supply-300x300.png?quality=85&strip=all 300w, https:\/\/i1.wp.com\/www.wehopower.com\/wp-content\/uploads\/2024\/11\/SP-3000-High-Power-Switching-Power-Supply-500x500.png?quality=85&strip=all 500w\" sizes=\"(max-width: 750px) 100vw, 750px\" \/><\/a><figcaption id=\"caption-attachment-7194\" class=\"wp-caption-text\">SP 3000 High Power Switching Power Supply<\/figcaption><\/figure>\n<p><img decoding=\"async\" src=\"images\/sp-6000-high-power-uav-charging-supply.webp\" alt=\"UAV Ground Power Units: Voltage &amp; Current Selection Guide  title=\" width=\"680\" height=\"680\" uav ground power units: voltage current selection guide title=\"\"><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Key_Specifications_to_Check_Before_Purchasing\"><\/span>Especificaciones clave para verificar antes de comprar<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Before committing to a UAV ground power unit, verify these eight items on the datasheet \u2014 not the marketing page:<\/p>\n<ol>\n<li><strong>Output voltage adjustment range<\/strong> \u2014 must cover your pack&#8217;s full-charge voltage with headroom.<\/li>\n<li><strong>Rated current and constant-current range<\/strong> \u2014 sustained, not peak, amperage at your operating voltage.<\/li>\n<li><strong>Ripple and noise<\/strong> \u2014 lower is better; spec sheets measured with a 20MHz bandwidth oscilloscope are trustworthy.<\/li>\n<li><strong>Line and load regulation<\/strong> \u2014 \u00b11.0% or better keeps output stable as mains and load fluctuate.<\/li>\n<li><strong>Funciones de protecci\u00f3n<\/strong> \u2014 short-circuit (constant-current foldback), overcurrent, overvoltage, and overtemperature shutdown with auto-recovery.<\/li>\n<li><strong>Efficiency and power factor<\/strong> \u2014 above 88% efficiency and PF\u22650.95 reduce heat and generator load in the field.<\/li>\n<li><strong>Temperatura de funcionamiento<\/strong> \u2014 \u221220\u00b0C to +60\u00b0C rated performance for outdoor and shelter installations.<\/li>\n<li><strong>Certificaciones<\/strong> \u2014 ISO9001 manufacturing, CE, RoHS, and FCC compliance for commercial deployment.<\/li>\n<\/ol>\n<p>Request burn-in test data as well.

Most commercial drones use 6S (25.2V full charge) or 12S (50.4V full charge) LiPo\/Li-ion packs, so the GPU should deliver an adjustable output up to roughly 26.4V or 52.8V respectively. Industrial UAVs on 14S packs need up to ~59\u201366V. Always choose a unit whose maximum output sits 5\u201310% above your full-charge voltage.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Can_one_ground_power_unit_charge_multiple_drone_types\"><\/span>\u00bf Puede una unidad de potencia terrestre cargar varios tipos de drones?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Yes \u2014 if the unit&#8217;s adjustable voltage range spans all your packs&#8217; charge windows and its current limit can be set per session. A 48V-class adjustable supply (0\u201352.8V, up to 62.5A on a 3kW model) covers everything from 6S mapping quadcopters to 12S heavy-lift platforms. For genuinely mixed fleets, units with analog or RS-485 remote control let you switch charge profiles without manual readjustment.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Is_a_portable_GPU_powerful_enough_for_fast_charging\"><\/span>\u00bf Una GPU port\u00e1til es lo suficientemente potente para una carga r\u00e1pida?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>For single-pack fast charging, usually yes. A modern 3kW portable unit delivers up to 62.5A at 48V \u2014 enough for 2C fast charging of packs up to about 30Ah. Limits appear with multi-pack parallel charging or sustained back-to-back cycles; there, a 6kW\u201310kW fixed unit with stronger thermal design is the safer choice.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_current_rating_is_needed_for_rapid_UAV_charging\"><\/span>\u00bf Qu\u00e9 calificaci\u00f3n de corriente se necesita para la carga r\u00e1pida de UAV?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Multiply pack capacity by your target charge rate. Examples: 16Ah pack at 2C = 32A; 22Ah at 2C = 44A; two 22Ah packs in parallel = ~88A. Then add 20\u201325% headroom so the supply isn&#8217;t running at its thermal limit. A 6kW\/48V unit rated at 125A comfortably covers most single and dual-pack rapid-charge scenarios.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Can_a_ground_power_unit_replace_my_drones_stock_charger\"><\/span>\u00bf Puede una unidad de energ\u00eda terrestre reemplazar el cargador de stock de mi dron?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>It can replace the DC source, but the charge-management function still matters. If your drone charges through its own BMS-controlled charger, feed it clean, well-regulated DC from the GPU. If you charge packs directly, pair the GPU with a balancing charger or specify a supply with precise current limiting (0\u2013100% adjustable) so the BMS never sees current beyond its rating.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"What_safety_features_should_a_UAV_ground_power_unit_have\"><\/span>\u00bf Qu\u00e9 caracter\u00edsticas de seguridad debe tener una unidad de potencia terrestre UAV?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>At minimum: short-circuit protection with constant-current foldback, user-settable overcurrent shutdown, overvoltage protection, and overtemperature shutdown with automatic recovery. For unattended or automated charging stations, add remote on\/off control, alarm signal output (dry contact), and MODBUS communication for fault monitoring.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Conclusion\"><\/span>Conclusi\u00f3n<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Selecting a UAV ground power unit comes down to three disciplined steps: match the adjustable voltage window to your battery&#8217;s full-charge voltage with headroom, size the sustained current to your charge-rate ambitions (plus 20\u201325% margin), and insist on the protection, regulation, and thermal specs that keep both your batteries and your flight schedule healthy. Whether you operate a single survey drone or a hangar of agricultural aircraft, the right GPU turns charging from a bottleneck into a non-event.<\/p>\n<p>WEHO has spent over a decade engineering adjustable high power switching power supplies for exactly these duty cycles \u2014 every unit passes full-load and high-temperature testing before it ships, and free samples are available so you can validate charging performance on your own packs.<\/p>\n<p><!-- CTA CARD 2 --><\/p>\n<table style=\"background-color: #db261e; border-collapse: collapse; width: 100%; margin: 24px 0;\">\n<tbody>\n<tr>\n<td style=\"padding: 22px 26px; text-align: center;\">\n<p style=\"color: #ffffff; font-size: 20px; font-weight: bold; margin: 0 0 8px 0; font-family: Arial, sans-serif;\">Get the Right Ground Power Unit for Your Fleet<\/p>\n<p style=\"color: #ffffff; font-size: 15px; margin: 0 0 14px 0; font-family: Arial, sans-serif;\">Browse WEHO&#8217;s adjustable high power SMPS series or tell us your battery specifications \u2014 replies within 1 hour, quotations within 24 hours, free samples for testing.<\/p>\n<p style=\"margin: 0;\"><a style=\"background-color: #ffffff; color: #db261e; font-weight: bold; text-decoration: none; padding: 12px 32px; font-size: 16px; font-family: Arial, sans-serif; display: inline-block;\" href=\"https:\/\/www.wehopower.com\/es\/contact\/\" target=\"_blank\" rel=\"noopener\">Contact WEHO for a Quotation<\/a><\/p>\n<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2><span class=\"ez-toc-section\" id=\"Related_Resources\"><\/span>Recursos relacionados<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<ul>\n<li><a href=\"https:\/\/www.wehopower.com\/es\/product-category\/adjustable-high-power-smps\/\" target=\"_blank\" rel=\"noopener\">Adjustable High Power SMPS Series<\/a> \u2014 WEHO&#8217;s full lineup of 1kW\u201310kW adjustable power supplies for charging and industrial applications<\/li>\n<li><a href=\"https:\/\/www.wehopower.com\/es\/news\/what-is-an-smps-switch-mode-power-supply\/\" target=\"_blank\" rel=\"noopener\">What Is an SMPS: Switch Mode Power Supply<\/a> \u2014 the technology inside every modern ground power unit<\/li>\n<li><a href=\"https:\/\/www.wehopower.com\/es\/news\/switch-mode-power-supply-advantages-disadvantages\/\" target=\"_blank\" rel=\"noopener\">Switch Mode Power Supply Advantages &amp; Disadvantages<\/a> \u2014 topology trade-offs that affect charging performance<\/li>\n<li><a href=\"https:\/\/www.wehopower.com\/es\/news\/why-automotive-oems-need-a-stable-long-term-power-partner-the-weho-approach\/\" target=\"_blank\" rel=\"noopener\">Why Automotive OEMs Need a Stable Long-Term Power Partner<\/a> \u2014 how WEHO supports high-volume charging programs<\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>Para los operadores de drones comerciales, equipos de inspecci\u00f3n y flotas de fumigaci\u00f3n agr\u00edcola, el tiempo de inactividad es una p\u00e9rdida de ingresos.
