BJ-QPW AC Active Power
Transducer
1. QPW transducer converts ac current and voltage signals into a
load independent dc signal proportional to active power (watt).
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 watt 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
