Descripción del producto

1. QPWK transducer converts ac current and voltage signals into a load independent dc signal
proportional to active power (watt) and reactive power (var). Two output signals combination in one
transducer.
2. The current and voltage signals are passed into the circuit via precision instrument transformers to
provide galvanic isolation between the circuits and the transducer circuitry. Each pair of current
and voltage signals is mathematically multiplied together to produce a product signal proportional to
true power and independent of wave shape and phase angle.
3. This var transducers to be connected to a variety of measuring and control devices and systems, such
as analogue meters, PLC, computers, data loggers, digital instruments and telemetry systems.
4. Snap on to DIN rail *5 x 7.5 mm complies with DIN-EN ****2 BS ***4
