Smart Controller (LCD Display) Gensave PRV-Z Series

Description

Precautions before use

This manual is only for the personnel responsible for installation, maintenance and operation.

1. The sampling voltage corresponds to the sampling current one by one, and the phases equence is the same.
2. The distribution sampling current terminals IA+, IA-, IB+, IB-, IC+,IC -must correspond to S1andS2 of phase A, Band C primary current transformers one by one.
3. For example, if the ratio is 500:5,it is set to 100.
4. Correctly set  the compensation current ratio of the primary current transformer in the compensation cabinet, for example,500:5,then set it to 100.
5. (only JK-GHY-D type, i.e. matching with composite switch)

For example, if the first output node corresponds to the three phase compensation type of 30kvar,itisset to 1  G-B 30kvar.

For example, if the second out put no de corresponds to the phase A of the split phase compensation type(0.25-15-3YN),itissetas2F-A5kvar.

Intelligent low voltage reactive power compensation measurement and control device.

Overview

PRV-Z series is an integrated controller for reactive power compensation and distribution monitoring, which integrates data acquisition, communication, reactive power compensation, power grid parameter measurement, analysis and other functions. If RS485 communication mode (JK-GHY-Z) is adopted for this product, upto 32 sets of HY series combined low-voltage power capacitor can be connected to the net work. Or choose 12V voltage output control mode (PRVD)-, which can provide 12 steps and 16 steps control output (only one of the two modes can be selected)
