Protection against network undervoltage

Protection against network overvoliage

30 A output current

5 KW output power

Having surge-absorbing timer

Having 7Segment display

U=220: Network voltage

T=240: ON delay

Signals:

RED Fault: ON Voltage under or over the allowed limit (on)

Delay: BLINK ON delay (blinking)

GREEN OUT: Guiput energization display

Principles of Operation:

Device starts working by network energization.

When network energizes. first. network voltage then ON delay time are shown on ciis- play.

Delay time (240 seconds) starts counting down and simultaneously. red signal blinks Till time ends.

Attention: tf voltage is under or over the allowed limit. timing does not start.

At the end of time. network voltage is shown on display: output energized and OUT signal gets ON.

lf volfage is under or over the allowed limit. output is de-enengized. green signal gets OFF and red signal (ON) gets ON.

lf network voltage gets back to normal. the above procedure repeats.

Installation and Start-Up:

Terminals MQ and PH have to be connect to network null and phase respectively. MQ and OUT terminals connect to air-conditioning compressor motor or single phase consumer.
