Function & Feature
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 35 x 7.5 mm complies with DIN-EN 50022 BS 5584
