T-VA Transducers

T-VA data sheet.

T-VA Apparent Power Transducers (VA)

The T-VA power transducers convert ac current and voltage signals into a load independent dc signal proportional to the apparent power (VA) flowing in the input circuit.

Optional VA-hour (T-VAH) transducers are a combined T-VA and T-INTP integrator in a common housing and give simultaneous VA and VA-hour outputs.
This does not apply to the T-2VA3 & T-3VA4, which because of limited space in the enclosure 100, is supplied as two separate units with the T-INTP integrator in enclosure 55.
