ROBA®-switch:

ROBA®-switch fast acting rectifiers are used to connect DC consumers to AC voltage supplies, for example, electromagnetic brakes and clutches (ROBA-stop®, ROBA®-quick, ROBATIC®), as well as electromagnets, electrovalves, etc.

The ROBA®-switch is used for operation at an input voltage of between 100 and 500 VAC, depending on the size. It can switch internally from bridge rectification output voltage to half-wave rectification output voltage. The bridge rectification time can be modified from 0.05 to 2 seconds by exchanging the external resistor (Rext).
 

• Consumer operation with overexcitation or power reduction
• Input voltage: 100 - 500 VAC
• maximum output current IRMS: 3 A at 250 VAC
