Harmonic controller |
 |
MACT type reactive power compensation controller is set grid monitoring parameters, harmonic, reactive power compensation and protection warning functions such as in the integration of new reactive compensation equipment, suitable for ac 0.4 KV, 50 hz low voltage power distribution system of monitoring and control reactive power compensation. High speed digital signal processor as the core, adopting ac sampling, FFT data processing. Man-machine interface is 128 * 64 dot matrix LCD display. A, technical parameters
Rated voltage: 220 v / 50 hz The sampling current: less than 5 a Stable working status: 0.85 ¡× 1.00 Over voltage protection: ¡× 280 v, 230 v, 5 v Under voltage protection: ¡× 200 v, 180 v, 5 v Voltage harmonic protection: ¡× 25% 5%, 15% by default The target power factor: 0.85 ¡× 1.00, step length of 0.01 The machine power consumption: 15 w or less Protection grade: IP30 Cutting way: circular cutting, first cast first cut Second, the product features
Mixer has overvoltage, undervoltage, lack of phase, the limit of the zero sequence current, harmonic oscillation judgment according to the limit and the system and rapid removal of the function of the capacitor Banks. Mixer control parameters of flexible, convenient to apply, no lose when power supply drop. Pieces according to the judgment of the power factor and reactive power, remove, or a set of input capacitors. Control capacitor you pitch in a first cut, circulation and combination of coding can extend the life of the capacitor as much as possible. Pieces can be automatic/manual operation. Mixer can real-time display system parameters and harmonic condition. |
