Three Phase Digital Ac Re Active Power Transducers With Rs485 - China

price: contact company for price

BJ- QPK Three phase Power Transducer

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


With three channel independent output for active/ reactive power

User free to correct the zero scale and full range scale, easy maintenance

1. Input: 0- 1A, 0- 5A, 110V, 220V/ 400V option

2. Output: 0- 5V, 0- 10V, 4- 20mA, 0- 20mA option ( One channel)

3. RMS measurement and output

4. Used in 3 PH AC

5.35mm Din rail mounting

6. RS485 port option
