BCS Series: Industrial AC-DC Converters

XP Power announces the BCS series of industrial supplies aimed at a broad range of applications that use battery backup to maintain equipment operation during a mains failure. The series offers 75 W, 100 W, or 155 W versions and are available with either 13.8 VDC or 27.6 VDC for 12 VDC or 24 VDC nominal outputs. The units provide a constant-voltage source to power the load. A separate constant-voltage/constant-current output charges the standby battery. An optional third 5 VDC/3 A regulated output is available across the range to supply logic, fans, or additional control functions.

In the event of a power loss on the AC input, the battery charging output switches to an input from the battery source providing a power source to the load. Protection features of the BCS series include battery overload, reverse polarity, output overvoltage, and output short-circuit that prevent damage to the load, the external batteries and the power supply itself. Control signals provide low-battery voltage disconnect, battery low warning, and AC OK.

The BCS75 (75 W), BCS100 (100 W), and BCS155 (155 W) models are enclosed metal-cased units and can deliver the full-load from -20°C to 50°C without derating or 70°C with derating. The 75 W and 100 W ranges are also available in an optional open-frame format.

Accommodating the full 90 to 264 VAC universal input range, the BCS series is suitable for worldwide use and carries EN/UL60950 approval for IT and industrial equipment.
