 Introduction

  The CVCF power is mainly applied to some remote areas or generator power supply voltage and frequency fluctuations, leading to load equipment can not work normally, and designed & developed. It can make the power of bad power voltage, frequency stabilization treatment, the output of high quality and high reliable CVCF power , and avoid load equipment hazards for the voltage frequency fluctuations large, waveform distortion. It use hill card CVCF power electric equipment is safe and reliable operation of the best protection.
Performance characteristics:
  1, wide the input voltage and frequency range
  2, the output waveform is pure sine wave
  3, The specifically design for North Korea grid environment
  4, applicable to various types of loading
  5, the larger range of choice , capacity 1KVA-2000KVA
  6, stable performance, the core components used of the original Japanese import

Method for Selecting Power Capacity

1. Resistance: Power Capacity = 1.1× Load Power


                  Load Starting Current
2. Induction: Power Capacity = ──────────────────── × Load Power
                  Load Rated Current

 

                                      Wave Crest Coefficient for Load Current
3. Rectification: Power Capacity = ──────────────────────────────── × Load Power
                            1.5


4. Mixed: Please properly select according to the percentage of different loads.

 

Note: For such inductive loads as refrigerator and air conditioning, the power capacity should be selected according to the starting power.
