PRE661 Multi-phase Relay Testing 3 Phase Relay Protection Test System

Product Description

Features
1. Built-in embedded industrial computer, with 10.1" LCD display, no need to connect to an external PC.

2. Linear power amplifier rather than switching power amplifier output, will not produce high and medium frequency interference on the test site.

3. USB interface, network port, GPS antenna interface are concentrated in the front panel, convenient for the operation.

4. With voltage short-circuit protection, overheat protection, overload protection and other protection functions.

5. Real-time storage of test data, convenient for output of test reports.
