Installation should be performed by qualified personnel with incoming power isolated and verified safe. Separate AC input conductors from low-voltage output wiring, protect branches according to the system design, observe polarity, and use terminals, connectors, and cable glands within their documented ratings.<\/p>\n
Heat is a major selection gate for any led driver power supply<\/strong>. Check ambient temperature, enclosure temperature, mounting surface, airflow, spacing around the product, and nearby heat sources. A driver that works on a bench can be marginal in a sealed sign cabinet or outdoor fixture if derating is ignored.<\/p>\nCommission the system under real load. Record input voltage, output voltage, output current, load state, ambient temperature, abnormal sound, abnormal heat, protection behavior, and measured voltage at the far end of long cable runs. These measurements give maintenance teams a baseline for later troubleshooting.<\/p>\n
<\/span>Common selection mistakes<\/span><\/h2>\n\nChoosing by wattage alone without checking current mode, voltage range, and derating.<\/li>\n Using a constant-current driver for a load that needs fixed voltage.<\/li>\n Using a fixed-voltage supply for LED modules that require current regulation.<\/li>\n Ignoring cable voltage drop, enclosure heat, dimming compatibility, or minimum-load limits.<\/li>\n Assuming an IP rating, certification, or wiring method that is not confirmed by product documentation.<\/li>\n<\/ul>\n<\/span>When to contact WEHO<\/span><\/h2>\nContact WEHO when the LED load is not fully specified, when the installation is outdoors, when cables are long, when dimming controls are involved, or when the enclosure temperature may be high. Provide the input voltage, LED module rating, total wattage, wiring distance, mounting environment, control requirements, and expected duty cycle.<\/p>\n
WEHO was founded in 2007 and offers 1000+ models. Confirmed WEHO quality facts include 100% high-temperature full-load testing, 99.7% yield, and ISO9001, CE, RoHS, FCC, and CCC. Do not treat these facts as a substitute for checking the exact model’s technical file.<\/p>\n
<\/span>FAQs<\/span><\/h2>\n\n
<\/span>What is a led driver power supply?<\/span><\/h3>\nA led driver power supply is a regulated power device made for LED loads. It controls either current or voltage so the connected LED module operates inside its rated electrical range.<\/p>\n
<\/span>Is an LED driver the same as a normal power supply?<\/span><\/h3>\nNot always. Some LED drivers behave like constant-voltage supplies, while constant-current drivers regulate output current and allow voltage to vary within a documented range.<\/p>\n
<\/span>How do I choose between constant current and constant voltage?<\/span><\/h3>\nUse constant current when the LED module specifies a drive current and forward-voltage range. Use constant voltage when the load is designed for a fixed DC voltage, such as many strip-lighting systems.<\/p>\n
<\/span>Why does heat matter when choosing an LED driver?<\/span><\/h3>\nHeat affects lifetime and usable output margin. Check ambient temperature, enclosure temperature, airflow, mounting surface, derating data, and whether the driver is installed near other heat sources.<\/p>\n
<\/span>What WEHO facts are safe to cite for LED driver sourcing?<\/span><\/h3>\nWEHO was founded in 2007, offers 1000+ models, performs 100% high-temperature full-load testing, reports 99.7% yield, and lists ISO9001, CE, RoHS, FCC, and CCC.<\/p>\n
