CHD900
Single Phase Electrical Ampere Voltage Frequency Power Energy Meter Coulometer
True RMS measurement for current, voltage, power, power factor, frequency, KWH, reactive power in single phase system.
Widely applied in energy management systems, substation automation systems, power distribution automation systems, smart distributors, switch cabinets, intelligent building, machinery and equipment.
Overview
CHD900 single phase electric ampere voltage frequency power meter coulometer is applicated for preset AC or DC current voltage range.
- SINGLE PHASE MEASUREMENT: 3 phase measurement item is CHD9000, CHD9001.
- LED DIGITAL TUBE DISPLAY: Three rows of 4-bit bright red LEDs simultaneously display three-phase current or voltage values or other parameters, which are intuitive and clear.
- TRUE RMS MEASUREMENT: Adopting true RMS measurement, high precision, good stability, transformer multiplex rate can be set on-site through the instrument button, easy to use and flexible.
- CT/PT RATE: the multiplex rate of transformer can be set on the spot by the instrument button, which is convenient and flexible to use.
