Power supply unit for mounting on DIN bus MEAN WELL (DRC-100B) with output current 2.25 A / 1.25 A, output voltage 27.6 VDC and wide input voltage range 90~264 VAC / 127~370 VDC. Low battery protection, battery polarity, overvoltage, overload, overheating and short circuit. Degree of protection IP20.
MEAN WELL DRC-100B is a DIN rail power supply designed for systems with battery backup of the output voltage. The model is a variation of the standard AC-DC power supplies, but unlike ordinary switching power supplies, it has a built-in UPS function and the ability to connect a battery.
The device provides uninterrupted power supply to consumers in the presence of input mains voltage, while simultaneously charging and maintaining the battery in standby mode. When the input power fails, the unit automatically switches to the battery and maintains the operation of the connected equipment without interruption.
This makes it a suitable solution for applications where reliable redundant operation is required - security systems, control panels, communication equipment, automation and other installations requiring constant power supply.
To correctly select the power and capacity of the battery, it is recommended to consult a specialist. It is important that the device is used as a UPS/charging module, and not as a standard switching power supply, since its function includes:
If these instructions are not followed, the device may be overloaded and stop functioning, and accordingly the warranty will not cover the damage.
