MEAN WELL. It integrates DC output, battery charge, uninterruptible power source (DC-UPS) and Modbus digital communication in tiny dimensions, thanks to microelectronics. The DRS series accepts the universal input between 90VAC and 305VAC. In addition to the key protection features, such as overload protection, over voltage protection, battery low voltage, disconnect and battery reverse polarity protection. The DRS series also provides Form-C contacts and LED indicators as alarm signals for AC-fail, battery low, charger circuit fail and DC-OK, allowing easy integration into security systems.

This series has 2-stage and 3-stage charge curves selectable by DIP switch, charging curves can also be programmed by SBP-001 as well as manual adjustment through a potentiometer (ADJ) on the panel to change charge current from 20% to 100%. The DRS series is suitable for Lead-acid and Lithium batteries with various capacities and can be remotely monitored by communication. The The DRS series is a DIN-rail type, digital security power supply launched by DRS series is a great solution for smart cities and building securities.
