Buy Huawei SmartPS-100A/250A from HYTECH
Why you should choose a SmartPS-250A-T0
from Huawei now.
The Huawei SmartPS-250A-T0 is a three-phase current sensor for use in solar power systems. The component processes a voltage of 176 to 288 volts and impresses with a very low power consumption of less than one watt. Installation is simple, easy and effortless. Once the sensor is integrated, it displays the power data via the built-in LCD screen and can also be operated effortlessly via it. In addition, the Huawei SmartPS-250A-T0 supports communication via RS485, so it can also be read out from another location. It uses the Modbus RTU communication protocol for this purpose.
Another outstanding feature of the current sensor is its enormous precision. The measurement accuracy of the voltage is +/-0.5 %, for the frequency the fluctuation is 0.01 Hz, current, power and energy are measured by the sensor with a maximum deviation of +/-1 %. This ensures that the sensor is classified in accuracy class >1. The other technical data should also be noted. The sensor is housed in a 100 x 72 x 65.5 mm case and weighs 1.5 kg, calculated including cabling. This allows a space-saving accommodation of the compact element. The possible operating temperature is between -25 °C and +60 °C, the component tolerates a relative humidity of 5 % to 95 %. Current can be measured up to 250 A. The scope of delivery includes three folding current transformers with 5 m cable length and an RS485 cable with 10 m length.
