When multiple doors are opened at the same time, the instantaneous peak load will increase exponentially.<\/div>\n<div class=\"ace-line ace-line old-record-id-OL6bfFFl1dsH1zc4ulfcrCt9nPb\">Many on-site system instability problems are caused by ignoring peak current. You must reserve 20%\u201330% current margin on the basis of total static load to ensure stable power supply under extreme working conditions.<\/div>\n<h3 class=\"heading-3 ace-line old-record-id-OdxXf6a37di2l8cKCBTcPOponT0\"><span class=\"ez-toc-section\" id=\"Determine_Required_Battery_Capacity\"><\/span>D\u00e9terminer la capacit\u00e9 de batterie requise<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"ace-line ace-line old-record-id-DUhFfvKgwdykFFcEQHecQt0Xnhe\">According to the total system load and the backup time required by the project, you can match the appropriate battery capacity. Light load and long standby time require large-capacity batteries; multi-door high-load systems need to balance battery capacity and power supply output power.<\/div>\n<h3 class=\"heading-3 ace-line old-record-id-XQW7fxaludDkoqcPt6ZcdHBynLh\"><span class=\"ez-toc-section\" id=\"Plan_for_Future_System_Expansion\"><\/span>Plan d'expansion future du syst\u00e8me<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"ace-line ace-line old-record-id-IZXDfeIBCdfCBhcFJVjcFGlnnaf\">Commercial building access systems often face later expansion and renovation.

WEHO multi-channel power supplies can perfectly adapt to later door expansion and function upgrading, avoiding repeated replacement of power equipment.<\/div>\n<h2 class=\"heading-2 ace-line old-record-id-QBoPfquyxdlwsDcsw2zc382En5c\"><span class=\"ez-toc-section\" id=\"_Common_Applications_of_Security_Power_Supplies_in_Commercial_Buildings\"><\/span>\u00a0Applications courantes des alimentations de s\u00e9curit\u00e9 dans les b\u00e2timents commerciaux<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<div class=\"ace-line ace-line old-record-id-ODJPfHbHQd0lBvcW51GcZIqmnLb\">Professional access control security power supplies are widely used in all kinds of commercial scenarios.

WEHO has targeted product models for all these scenarios, meeting your diverse project procurement needs.<\/div>\n<h2 class=\"heading-2 ace-line old-record-id-FUqnf298zdO9MaceSwTc6wsdnnK\"><span class=\"ez-toc-section\" id=\"FAQs\"><\/span>FAQ<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3 class=\"heading-3 ace-line old-record-id-Wj7lfNtxIdNgyCcFbVSc4TZjnMo\"><span class=\"ez-toc-section\" id=\"What_voltage_do_access_control_power_supplies_use\"><\/span>Quelle tension utilisent les alimentations de contr\u00f4le d'acc\u00e8s?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"ace-line ace-line old-record-id-RrlQf2AW4dVuoTcnl9oc4HyXnVe\">Most mainstream commercial access control devices adopt 12V DC working voltage, which is also the mainstream specification of WEHO security power supplies. A few special industrial access devices use 24V DC. You need to confirm the voltage standard of on-site equipment before procurement to avoid mismatch.<\/div>\n<h3 class=\"heading-3 ace-line old-record-id-JSwdfjm3vdkaIjcTHrncOKHkn9d\"><span class=\"ez-toc-section\" id=\"Do_access_control_systems_need_battery_backup\"><\/span>Les syst\u00e8mes de contr\u00f4le d'acc\u00e8s ont-ils besoin d'une batterie de secours?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"ace-line ace-line old-record-id-JdRTfiha5dU4OTctRtBcN9DHnXc\">Commercial access control systems must be equipped with battery backup. It is not only to ensure normal access during power outages, but also a basic requirement for commercial building fire safety acceptance. Only residential simple access systems can cancel backup power as appropriate.<\/div>\n<h3 class=\"heading-3 ace-line old-record-id-LWbBfmZc7dGFlUcTrzOc2iDMnAe\"><span class=\"ez-toc-section\" id=\"How_long_can_a_backup_battery_power_a_door_access_system\"><\/span>Combien de temps une batterie de secours peut-elle alimenter un syst\u00e8me d'acc\u00e8s \u00e0 la porte?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"ace-line ace-line old-record-id-XsZOfgkwOdLxY3cLoyJcgpiXnxe\">The backup runtime depends on battery capacity and total system load. A standard 7Ah battery can support 1\u20132 access doors to work stably for 2\u20134 hours. The more access devices, the shorter the standby time. You can configure different battery combinations according to project requirements.<\/div>\n<h3 class=\"heading-3 ace-line old-record-id-HAg7fMAuHdsVzGc5F4ccZ3pknZc\"><span class=\"ez-toc-section\" id=\"Can_one_power_supply_support_multiple_doors\"><\/span>Une alimentation \u00e9lectrique peut-elle supporter plusieurs portes?<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<div class=\"ace-line ace-line old-record-id-WvqOfkE4TdQgX4cHbtRcDpFHnxh\">Yes. Professional multi-channel security power supplies can support multiple access doors at the same time.
