Description
With the three-phase system monitoring module, both a.c. and
three phase systems can be monitored for falling below a set value. The set
value is adjusted to 70% of the rated voltage according to VDE DIN 0108/0109
for emergency lighting installations. The module can monitor a maximum of three
random phases, each conducting a voltage of 220 V AC against zero.
The closed-circuit working electronics activate a relay (two changeover
contacts) on reaching the adjusted limiting values. Depending on the
parti-cular application, changeover to safety devices can take place isolated.
The delay (ON/OFF) of about 500 ms prevents the electronics from operating if
the set value is briefly not reached. This module is not suitable for neutral
loads.
