EPOCH-II

High-Current Output Unit

DESCRIPTION

The EPOCH-II

is a high-current output unit designed to

be controlled by the PULSAR

in combination with the

High-Current Interface Module to produce a rugged,

portable high-current, high-volt/ampere test set.

The EPOCH-II also is designed to be controlled by the

EPOCH-10

Relay Test Set.

PULSAR/EPOCH-II or EPOCH-10/EPOCH-II combination

uses microprocessor-based, digitally synthesized sine wave

generators and solid-state regulated power amplifiers to

provide sinusoidal voltage and current outputs with

precise control of the phase-angle relationships.

These combinations will produce accurate test results even

with a fluctuating power source or when testing nonlinear

or highly saturable relays.

An optional IEEE-488 GPIB interface transforms the

EPOCH-10/EPOCH-II combination into a programmable

automatic test system when used with an external

controller or computer. Amplitude and/or phase angle can

be set to desired values, step changed, ramped, or pulsed

to new values.

APPLICATIONS

PULSAR/EPOCH-II or EPOCH-10/EPOCH-II combination is

designed to test both complex protective relays which

require phase-shifting capability and simpler relays,

including all overcurrent relays.

The table above lists the different types of relays by

device numbers, and the different combinations of a

PULSAR or EPOCH-10s and an EPOCH-II required to test

them.

FEATURES AND BENEFITS

■

Output current source has a 5-minute duty cycle rating

of 1000 volt-amperes.

■

Four output ranges at 0.01 ampere and two output

ranges at 0.1 ampere are provided.

■

Tough steel, sealed enclosure provides a high shock

and vibration resistance.

■

Completely compatible with PULSAR via the High-

Current Interface Module and the EPOCH-10 units.
