T and R DVS3 MK2

The DVS3 MK2 is the Smaller, Lighter & Higher Power Version of the T&R DVS3, Offering Three Times the Output Power of the Original DVS3

The exceptionally easy to understand user interface of the DVS3 is retained, allowing simple testing of complex voltage and loss of mains protection systems.

The DVS3 MK2 is a truly flexible system. The DVS3 MK2 has been designed using the latest digital technology to generate a highly stable and accurate output with very low distortion. Each phase output is individually adjustable for voltage and phase angle. In addition, full control of frequency is available. Step changes of any quantity may be generated with automatic timing of the response of the relay under test.

The T&R DVS3 MK2 three phase digital voltage source provides a 3 phase source from a single phase input. Compact and portable, the DVS3 is either used alone or in conjunction with a current injection test set to test virtually all single and multi-phase protection relays.

The DVS3 has many features including phase shifting, variable frequency, 45VA/phase maximum output, large back-lit liquid crystal display and an automatic mains voltage selection.
