The SCR Elektroniks make relay heating test bench is a low cost heating test bench to test the continuity of bimetallic overload relays against over current. The bench is customizable for 5, 6, 12, 24 and 48 stations as per the customer requirement.

The bench is inbuilt with a servo controlled ac current source ideally optimized for a huge current range: 0.5 – 22 A and thus a wide range of relays can be tested. The current measurement is of class 1 and is implemented using a multi tapped CT ensuring accuracy for the entire range. An inbuilt microcontroller based timer decides the timing of the test.

The system comes inbuilt with as many fixtures as the number of stations, one each to hold one relay. In addition, each fixture is equipped with a special feature: Each fixture has its own NO / NC indicator making it ideal even for an unskilled operator to operate and decide the compliance of the relay under test.

The incomer electrical connection is protected by an MCB while the incoming air connection (for pneumatic fixture) is with an air guage which would warn the operator about air pressure.
