Price Match Guarantee & Advice

Sleek, lightweight and capable of generating even more power than the mk1 version, the T & R DVS3 mk 2 is ideally suited for testing G59 protection, including loss of mains protection.

In addition, this system is suitable for use with vector surge and df/dt (ROCOF) relays and under/over frequency relays, under/over voltage relays, synchronising relays and transducers.

The DVS3 is made to generate highly stable outputs and reduces distortion to maintain accuracy during a test. Users have full control over phase output with individually-adjustable controls for both voltage and phase angle available.

This relay tester’s built-in timing system is also designed with flexibility in mind. Step changes of any quantity can be easily generated by typing in values on the keypad and it’ll automatically reset and start the timer once changes are made. For extra control and additional functionality, there’s also a PF-F-PF mode.
