Compact current converter COMBITRON 91

DCswitchingEMI-filtered

Product description
COMBITRON 91 rectifiers are half-wave or bridge rectifiers for supplying electromagnets with a supply voltage up to max. 720 V AC for DC- or AC-side switching in accordance with the 73/231/EEC Low Voltage Directive. When switching electromagnetic clutches, brakes or other inductive DC loads, electromagnetic interference can occur. The half-wave variant with interference suppression reduces emissions to class A according to EN 55011.

Highlights

• Half-wave or bridge rectifier
• Up to 720 V AC maximum input (depending on variant)
• UL-certified
• Compact design in plastic housing
• DC-side and AC-side switching supported
