Intelligent Low Voltage Protection Devices Smart Low Pressure Unpaid Controller

Product description
JK-8CKZ(H) series intelligent low voltage reactive power compensating controller, a new generation, is designed by our company to meet with latest reactive compensating requirement, has good figure, general mounting dimension. And it provided LED, LCD display and push-key for operation, connected with intelligent power capacitor. Control parameters cover voltage, current, power factor, and reactive power. On basis of present reckon methods of reactive trend and tide, it specially suits for the site where power factor change very largely, switching is not frequent, and high control accuracy required

Main functions
Dynamic display each electric parameters, and parameter setting is simple, not lost even if power failed.
Automatically detect the number and capacity of the intelligent capacitors, and control switching intelligent capacitors on basis of network parameters and settings.
It provided the protections of over-voltage, under-voltage, undercurrent, over-temperature, when the parameter exceeds the setting, the controller will cut off the switched-on capacitor and lock its output, to protect capacitor safely in service and extend its service life.
Comprehensively analyze voltage, current, power factor, and reactive power, in consideration of voltage returned difference, make the control more accurate, and prevent switching shake.
Within the delayed time of switching, it collects the signals of abovementioned parameters from several points, analyze reactive power trend on basis of these parameters, this is to avoid wrong decision that common controller with only one sampling point will happen often, in the case that power factor change much, it can determine the required reactive power and compensating operation (switch on or off) accurately.
Hand/Auto shift function provided, when in Auto position, it can control switching on/off the capacitors according to voltage, load, power factor and shortage of reactive power; if in Hand position, you can switch on/off capacitors by hand, this used to commission the product during ex-works or control the capacitor quickly.
Output under code and circulation, the capacitors with same capacity will be switched in cycle to extend their service life. If the capacity is different, the capacitors will be coded, the controller selects the capacitor with proper capacity to switch on/off dynamically, which can improve the compensation accuracy and reduce the switching times.
