Application


JKWF Series controller regards 8 single-chip microcomputer as core, adopts the control scheme of phase splitting sampling and compensation and common compensation and phase splitting compensated altogether, very suitable for reactive compensation with 50Hz, 0.4KV three-phase load imbalance power system.


Function characteristic


1.LED display the three-phase voltage, current, active power, reactive power, power, power,?power factor and power network frequency, control parameter, etc..(With this controller can save ampere meter, voltmeter, universal change-over?switch, etc in the cabinet.).

2.Strong anti-interference ability can resist ?2000V interference pulse from power direct, and not crashing, does?not lose the data, it is reliable to run steady.

3.Reactive power control physical quantity, high control precision;

4.The suer can revise the control parameter according to his own need, the control parameter is not lost to have?a power failure.

5.With automatic discriminating phase function(sampling signal automatic ?be kept in the same state).

6.The input resistance of current sampling signal is smaller than 0.05Ω; ?it can be taken out from measuring loops directly.

7.With over-voltage, under-voltage, imperfect phase ?protective ?function.

8.Compensation mode:phase splitting compensation, phase splitting splitting compensation and three-phase?compensation, the three-phase compensation.

9.Output mode:static state, dynamic state, compound etc.

10.Output loops 1-12 Loop
