The RTA1 is an adjustable current source compatible with the RT150. An external contact load of up to 10 amperes may be used to measure contact voltage drop. The RTA2 is a test adapter multiplexer, allowing two identical test fixtures to be used on a single tester. While the operator is loading a relay into one fixture, the relay in the other fixture is being tested. The AP1A is an optional AC power supply used for testing AC coil relays.
Interface cabling is included with the supply.
