| Megger / AVO / Multi-Amp EPOCH-40 Dynamic Timer and DC Relay Test Set
The Multi-Amp EPOCH-40 test set combines
regulated dc voltage and current sources, a microprocessor based digital
timer and a special potential switching circuit. It was designed to
provide a rugged, portable timer and auxiliary dc voltage and current
unit. The Multi-Amp EPOCH-40 can be used with other members of the Multi-Amp
EPOCH family.
The timer is used to measure the elapsed
time of operation of the relay under test It incorporates start and stop
gates to monitor the contact opening or closure, the "firing" of
a trip circuit SCR and the application or removal of an ac or dc voltage
signal.
When the Multi-Amp EPOCH-40 is combined
with the Multi-Amp
EPOCH-10, electromechanical or solid-state relays can be easily
tested. The Multi-Amp
EPOCH-10 and Multi-Amp EPOCH-40 combination can be used to perform
timing tests on many commonly used relays. The table below is a brief
listing of the different types of relays by device number that a single
Multi-Amp EPOCH-40 can be used to test.
