Environment condition

Ambient temperature: - 25 ℃～ 70 ℃ in operation, - 40 ℃～ 85 ℃ in transportation and storage

Relative humidity: 20% ～ 90% at 40 ℃

Atmospheric pressure: 79.5-106kpa (altitude 2500m and below)

Working voltage of power supply

220 V ± 20%; frequency 50 Hz ± 5%; total distortion rate of sine wave ≤ 5%

Measurement accuracy 

Voltage analog (10% - 100% maximum): 0.5 level

Current analog (1% - 100% max): 0.5 level

When the phase angle ∮ is between - 30 ° and + 60 °, the power level is 0.5 and the power factor level is 0.5

Switching mode

Switching mode: intelligent analysis switching (connected capacitors can be arranged arbitrarily)

Parameter description
