3-phase 4-wire AC Multi-parameter digital transducer
This product is an intelligent isolation transducer of electrical parameter acquisition and transmission. It can measure the full-parameter of three-phase four-wire AC loop. Using high-precision 24-bit dedicated AD chip, the ratio dynamic range can be up to 5000: 1, the measurement parameters are voltage, current, frequency, active power, reactive power, power factor, total accumulative energy and other electrical parameters with high accuracy, good stability and high communication speed. The completely isolated processing technology is with anti-interference ability. Measurement of electrical parameters through the RS-485 digital interface output to achieve long-distance transmission, the product MODBUS protocol is complete compatible with a variety of configuration software or PLC equipment MODBUS (RTU) protocol. It can be applied to power, room monitoring, industrial measurement and other fields

Wide power supply
Different Auxiliary power, different power consumption
Input/output: 2500V DC for 1 min
Input/power supply: 2500V for 1 min
Output/power supply: 2500V for 1 min
he double isolation part numbers, their output and power supply are grounded together, there is only between the input and output isolation voltage
2 x voltage span 1 sec. 10 for times with interval of 10 sec.
10 x current span for 1 sec. 5 times with an interval of 300 sec (only for hole thru. parts)
The input outside the linear range will result in poor accuracy
