Trusa curent-tensiune injectie secundari Cotel MG 30-N

Cod: Cotel MG 30-N


 
Brosura produs PDF, 1.46 Mb

Descriere

 

125A max

250V

 

 

The MG 30-N is a rugged and powerful injection set which is especially

suited for testing over or under current or voltage relays. It is also suitable

for testing chneider Statimax type relays which are powered from the measurement

connection.

This instrument has one generator which serves both for current and

voltage, and a digital measurement and recording module with a large graphic

display. This enables measurement of the true RMS value of the current and

offers advanced timing and injection control functions.
