JKW5 series Reactive power automatic compensation controller,according to the control physical quantity is divided into JKG and JKWis,is applied to automatic adjust controller of capacitor compensation device of low-voltage distribution system,to make power factor reach on the expect state and improve utilization efficiency of power transformer,and reduce circuit consumption,improve the quality of power-supply voltage.
Normal operational conditions and installation conditions
3.1 Temperature: Max +50ºC, Min -25ºC
3.2 Altitude: no higher than 2500m
3.3 The relative humidity: no more than 50%,when temperature is +40ºC.The product can withstand higher humidity under lower temperature,for instance,when it at +20ºC,the production can withstand 90% relative humidity.
The condensation that happened because of temperature changes should be taken care.
And Installation location should have no exploresion danger, and no gas and conductive dust which can cause corrosion and insulation damage.
3.7 Installation:shall have no obvious vibration.
