UNDER OVER VOLTAGE TIME RELAY

UNDER OVER VOLTAGE TIME RELAY .
UNDER/OVER VOLTAGE TIME RELAY - Didactic equipment:
module with insulated panel, under/over voltage time relay, relay for monitoring the over-voltage and the under-voltage in an alternating three-phase mains.
Max adjustable set point: 0/+20% of the rated voltage. Min adjustable set point: 0/+20% of the rated voltage.
Adjustable delay timer activated when the max. set point is exceeded.
Adjustable delay timer activated when the min. set point is exceeded.
It must be possible to connect the three-phase line 3x380V to the terminals.
One output relay with two change over contacts: (5A – 230Vac) with resistive load.
NC contacts: device not supplied or in alarm
Self-supplied by the voltage to be monitored: (380 ÷ 418)
4 mm. safety terminals and 2 mm. terminals included on the front panel for the electrical connection.
