REGULATED SWITCH RIDES DIN RAILPhaseo regulated switched-mode DC power supplies are available in three models, all with overload, short-circuit, over-voltage and under-voltage protection. Models include single-phase and three-phase units with 100-520 V inputs, 12 or 24 Vdc outputs, and ratings of 10-40 A. All three deliver a voltage accurate within 3%, regardless of load and supply voltage. They are UL listed and CSA certified, and conform to IEC standards.
