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.

Features

Easy to use low cost benchServo controlled current source for line and load regulation (1%)Continuity IndicationManual Operation possibleIn built timer to pre set the total time of the test: Universal for all stationsNO / NC indication on each fixture

The bench has a facility to test multiple relays simultaneously and independently of each other in a modular fashion. Each test station has its own SMPS based current source (that sets the desired test current instantly), a pneumatic fixture, a micro-controller based logic controller to control the current and a small NO / NC indicating lamp to instantly indicate to the operator the status of NO / NC contact.
