120W - 240W DIN Rail Mount
Three Phase Power Supplies
The DRB120/240-3 series supports the growing trend for simple and economically priced 3-phase input 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 94%. Conservatively rated electrolytic
capacitor temperatures offer improved field life-times of typically 10 years. Available in two power levels, 120W and 240W, the series provides a choice of
12V, 24V and 48V outputs. All models can provide a peak power of 120% for up to 2s to handle capacitive loading. A low energy inrush current level avoids
nuisance tripping of circuit breakers. Units can be connected in parallel to provide more power or for redundant applications. A DC Good relay, remote on/off
and a choice of models with either screw or push-in wire terminals.
