1. General
The controller is suitable for automatically adjusting of low voltage distribution sytem capacitor compensating device to make power factor get user’s predetermined state, increase service efficiency of power transformer reduce line loss,and inprove the voltage of power supply.
2. Normal working and installation conditions
2.1 Ambient temperature: -25℃~ +55℃
2.2 Relative humidity: 40℃≤20%；20℃≤90%
2.3 Altitude: ≤2500m
2.4 Environmental conditions: no noxious gas and vapour; no conductivity or explosive dust;
no violent mechnical vibration.
3. Main structural features
3.1 The capacity of the switched capacitor is calculated according to the reactive power and the compensation precision is high.
3.2 High measuring precision of power factor and wide display range.
3.3 Initial phase presetting (same polarity or current signal polarity is adjusted by software).
3.4 Provided with two control modes such as power factor control mode and reactive power controI mode.
3.5 Friendly hUman-machine interface with convenient operation.
3.6 Various fully digitalized control parameters，adjustable and visual with convenient use.
3.7 Provided with two working modes such as automatic and manual running.
3.8 Provided with protection functions for over-voltage and under-voltage.
3.9 Provided with protection function for power failure to avoid data loss.
3.10 Low current signal input impedance, ≤0.01Ω.
4. Ordering notes
Users should supply the number of circuits, rated voltage, and type of switch (contactor or combination switch).
