Powerless power compensation controller (common complementary type) (FTJKW)

Powerless power compensation controller (common complementary type) (FTJKW)




Product Introduction



Ambient temperature: -25°C to +65°C

Altitude: no more than 2000M

Atmospheric conditions: air humidity not exceeding 90%

Environmental conditions: media free of conductive dust


Implementation standards:

Power Industry Industry Standard "DL/T597-1996



The installation, maintenance and operation of the controller must be carried out by personnel with the relevant professional knowledge and skills.

Ensure that the operating voltage of this controller is within the range of AC 380V ± 20%, 50Hz ± 10%.

Do not open the housing of the controller at will to prevent electric shock.

Before disconnecting the current transformer from the controller, make sure that it is short-circuited or connected in parallel with another load of sufficiently small impedance to be worthwhile.


Technical Special:

Control of physical quantities: reactive power, no compensation dull zones, small loads without throwing oscillations.

Automatic phase sequence identification function: when the input B and C phase voltages and A phase currents are correctly wired, the secondary terminals S1 and S2 of the power transformer can be connected at will without affecting the correct operation of the controller (see Note 1, P26)

Coding cut function: cyclic cut and various coding methods are possible.

◇EMC electromagnetic compatibility, ETF group pulse immunity up to 4000V class A (the highest level of international electrical standards), has passed the test of the International Relay Quality Supervision and Inspection Centre, with the "EMC Inspection Certificate" issued by this institution.
