ROBA®-switch Type 017.110.2
Application
ROBA®-switch fast acting rectifier units are used to connect DC units to alternating voltage supplies, for example electromagnetic brakes and clutches (ROBA-stop®, ROBA®-quick, ROBATIC®), ectromagnets, electrovalves, etc.
Fast acting rectifier ROBA®-switch 017.110.2
• Consumer operation with overexcitation or power reduction
• I ntegrated automatic DC-side disconnection (shorter connection time)
• I nput voltage: 100 - 500 VAC
• Max. output current IRMS : 1,5 A
• UL-approved
E189728 V V
The ROBA®-switch units with integrated automatic DC-side disconnection are not suitable for use as safety disconnections!
Dimensions (mm)
Function
The ROBA®-switch units are used for operation at an input voltage of between 100 and 500 VAC, depending on the size. They can switch automatically 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).
The ROBA®-switch units also have an integrated automatic DC-side disconnection. In contrast to the conventional DC-side disconnection, no further protective measures or external components are necessary. The DC-side disconnection is stand­ard-activated (terminals 3 and 4 are not wired), resulting in short electromagnetic consumer switching times.
The integrated automatic DC-side disconnection is deactivated by fitting a bridge between the terminals 3 and 4. The coil is deener-gised via the free wheeling diode. This has the advantages of softer braking and a lower switching noise. However, the switching times increase (taking approx. 6 - 10 times longer).
