Product Description

      Ship voltage and frequency stabilisation power supply is mainly for ship generator voltage and frequency fluctuation is large, and lead to the load equipment can not work normally and design and development, the ship voltage and frequency stabilisation power supply can be voltage stabilisation, frequency stabilisation processing of the power supply, the output of high-quality, high-reliability voltage and frequency stabilisation power supply, to avoid due to the voltage and frequency fluctuation is too large, the waveform distortion is large and the hazards of the load equipment.
      The working principle of ship voltage and frequency stabilised power supply is alternating - direct - alternating principle after svpwm space vector pulse width modulation method, so that the generator voltage after re rectification and inversion, in line with the rated voltage of the local load, that is to say, the ship voltage and frequency stabilised power supply can be simulated in other countries of the power grid, and the carrying capacity is strong, it is a kind of ideal power stabilisation equipment.

Main Parameters:
1, Input voltage: single-phase 130-300V & three-phase 260-500V
2, Input frequency: 35-70hz
3, Output voltage: Single phase ,split phase or 3 phase ±0.5%.
4, Output frequency: 50hz/60hz ± 0.01%
5, Conversion efficiency: ≥92%
6, Dynamic response: ≤ 20ms
7, Waveform distortion: ≤ 3%
8, the original Mitsubishi sixth-generation intelligent module IPM, the United States dsp28335 control chip, isolated transformer output, stable and durable. Over-voltage, over-current, short-circuit and overheating device, 32-bit microprocessor control, lcd liquid crystal + led alarm indication.
9, suitable for three-phase balanced and any unbalanced load, can also be used as a single-phase power supply. It can adapt to resistive, capacitive, inductive and other types of loads and mixed loads. Dual mode start function, frequency conversion start and reduced voltage soft start function. It can overcome the problem of starting shock with high power motor. Save money.

10, Power range: 3kw-200kw, can be customizedto customer's requirements.
