Ac Re Active Power Transducer Bj Qpk - China

Function & Feature

1 - QPK transducer converts ac current and voltage signals into a load independent dc signal proportional

to reactive power (vars).

This signal is capable of driving a number of independent instruments.

2 - The current and voltage signals are passed into the circuit via precision instrument transformers to

provide galvanic isolation between the input 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 - These 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 35 x 7.5 mm complies with DIN-EN 50022 BS 5584
