DRC-180B 180W Single Output Power Supply with Battery Charger (UPS Function), 27.6 V Output

The DRC-180 series is a line of 180W AC/DC DIN rail power supplies for security systems. In addition to the main output, there is a charger output with a lower rated current, enabling the backup power application required by access control and security systems. The DRC-180 accepts universal input between 90VAC and 264VAC and outputs 13.8VDC and 27.6VDC respectively. With an efficiency up to 90%, it can operate with natural convection cooling at temperatures between -20℃ and 70℃. In addition to main protection functions such as overload protection, overvoltage protection, low battery cut-off, and battery reverse polarity protection (via fuse), an alarm signal for "AC OK" and low battery is provided via relay contact output, to facilitate system design.

#### The DRC-180B model has an output voltage of 27.6 V
