0 2s Measurement Accuracy 500s Response Time With 3 1 Channel Output Electrical Monitor - Chinaprice: contact company for price
1. QPCX electrical transducer converts ac current and voltage signals into a load independent dc signal
proportional to active power ( watt) , reactive power ( var) and power factor ( PF) . With an extra output
channel for customized. Total four channel output for electrical data sampling use.
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. This combination transducers with RS485 communication port, it can 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.
