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
®
),
electromagnets, electrovalves, etc.
Fast acting rectifier ROBA

-switch 017.110.2
Consumer operation with overexcitation or power reduction
• Integrated automatic DC-side disconnection
(shorter connection time)
• Input voltage: 100 - 500 VAC
• Max. output current I
RMS
: 1,5 A
• UL-approved
The ROBA
®
-switch units with integrated automatic
DC-side disconnection are not suitable for use as safety
disconnections!
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 out-
put 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 (R
ext
).
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 stand-
ard-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
deenergised 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).
