Brief Introduction

DRC-40A

The DRC - 40 series is a 40W DIN - rail type AC - DC safety power supply that complies with German industrial standards. In addition to the main output, it also has a charging output with a relatively small rated current to provide backup power, facilitating the needs of safe access to the system. The DRC - 40 allows a full - range input from 90VAC to 264VAC and provides 13.8VDC and 27.6VDC outputs respectively. It can achieve an efficiency of up to 87% and can operate under natural air cooling conditions at temperatures from 30°C to 70°C.In addition to the main protection methods such as overload protection, over - voltage protection, battery low - voltage cut - off, and battery reverse - polarity protection (via fuse), it also has AC OK and battery low - voltage alarm signal outputs. The standard type can be output through a TTL open - collector (the selectable type can be output constantly through a relay).
