Target / Personal Care / avo megger multi amp pulsar test system 10e3t3n 1 (919). Manual toothbrush. The PULSAR® Universal Protective Relay Test System represents the next generation in protective relay testing. PULSAR can be connected to the Multi-Amp EPOCH-20‚ and EPOCH-II‚ High-Current Output Units. The Multi-Amp. Manual or Computerized Control PULSAR can be operated manually by simple, front-panel.

EPOCH-II ® High-Current Output Unit ■ 1000 VA of high current ■ Rugged, portable test set ■ Up to 187 Amperes maximum output 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.
