120W - 480W DIN Rail Mount Single Phase Power Supplies
The DRB series supports the growing trend for simple and economically priced DIN power supplies for industrial and process control applications. The series
combines low cost, reliability and compact dimensions with energy saving efficiencies of up to 93%. Conservatively rated electrolytic capacitor temperatures offer
improved field life-times of up to 10 years. Available in three power levels, 120W, 240W and 480W, the series provides a choice of 12V, 24V and 48V outputs.
An opto-isolated DC OK signal is fitted for remote monitoring.
