TESSET 502

FEATURES:

SET facility practically eliminates the possibillty of damaging relay while adjusting the current.

Built in choke for sinusoidal current waveform and improved control when testing electro-mechanical relays.

Built in Timer for measuring relay tripping time. Operates from normally open or normally closed contacts.

Built in auxiliary supply for energizing electronic relays, trip coils etc, controlled by seperate variable transformer.
