Application
ROBA
®
-multiswitch fast switching modules are used to
connect DC consumers to alternating voltage supplies,
for example electromagnetic brakes and clutches (ROBA-
stop
®
, ROBA
®
-quick, ROBATIC
®
) as well as electromagnets,
electrovalves, etc.
Fast acting rectifier ROBA
®
-multiswitch 019._00.2
• Consistently controlled output voltage in the entire input
voltage range
• Consumer operation with overexcitation or power
reduction
• Input voltage: 100 – 500 VAC
• Maximum output current I
RMS
: 2 A; 4.5 A
• UL-approved
Function
The ROBA
®
-multiswitch is used for operation at an input
voltage of between 100 and 500 VAC, depending on the
size. After switch-on, it emits the rectified bridge voltage for
50 ms and then adjusts automatically to a pre-programmed
overexcitation voltage. After the overexcitation time ends, it
regulates to the permanently programmed holding voltage.
For the overexcitation voltage and holding voltage values of
the standard design, please see the Table at the bottom of
page 3.
On special designs, deviating values are possible.
The overexcitation time can be adjusted via a DIP switch to
150 ms, 450 ms, 1 s, 1.5 s and 2 s.
Electrical Connection
(Terminals)
1 + 2 Input voltage
(fitted protective varistor)
3 + 4 Connection for external contact
for DC-side switch-off
(with an installed bridge, switch-off
only takes place AC-side with a longer brake engagement time)
5 + 6 Output voltage
(fitted protective varistor)

-multiswitch units are not suitable
for all applications, e.g. use of the ROBA
®
-
multiswitch when operating noise-
damped brakes is not possible without
taking additional measures. The product’s
suitability should be checked before use.
