Product Description

 

0.5 Class 4Channel Output  3P Power Transducer

 

AC combination 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.

 

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.

 

Function & Feature

 

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.

 

4. Snap on to DIN rail 35 x 7.5 mm complies with DIN-EN 50022 BS 5584
