Inverting power supply

  Adopt advanced sine wave pulse width modulate IGBT high frequency inversion technique, inside is AC-DC-AC structure, eliminate the electricity net disturb, output pure wave, stable voltage and frequency, high precision, light weight, small volume, output use isolation transformer. It can cooperate with the generator to make good quality uninterruptable power supply system.

  Quay ship high power frequency conversion  power supply is especially used on ship, shore quay, where the environment is very bad, with high temperature, high humid, high erosive, and large load. All the PCB boards adopt coat solidification process, sine wave filter and output transformer which adopts whole vacuum dipping isolation lacquer and sprays high temperature protection lacquer, with high isolation degree and protection ability, completely accords with Chinese ship’ classification society CCS attestation standard. It is widely used on ship, ship manufacture and repairing factory, ocean making hole flat roof and shore quay, where need to change 50Hz industry electricity to 60Hz high quality stable frequency and voltage power supply, and also for the equipments on the ship

  EPS is a spare power supply device which is installed in the building. When the building’s electricity is broken off because of fire, accident of some other emergency, the EPS can supply the second circuit power supply for the fire fighting sign light, floodlight and other important load. With the improvement of the building fire fighting level, especially the increasing of the high, big building s, the centralizing EPS has become integrant firefighting device of the building

  ZJWL-45 inversion power supply inverts DC24±8V of armor tank to AC220V, and supply power to air condition, instrument and so on, this kind of products is manufactured strictly according to the nation military standard, and also make a series of military products test, such as high temperature test, electromagnetism compatibility, impulsion and shake, sand test, humidity test and so on.

  This kind of power supply is specially designed for the new energy sources power supply, which is mainly used in the PV power station, wind power generating station, wind, light, oil, storage mutual generating system and consumer solar energy power supply system.  Features: ★Pure sine wave output, pure and steady★The output adopts the isolation transformer, the output voltage is steady and safe.★High reliability, high efficiency★Green, environment keeping and patent products★Can combined the inverter and the controller, high cost performance ★Perfect protection function for lack of voltage, over load, over heat, short circuit and backing

  The system adopts online double transform structure design, completely eliminate the disturbs on the electricity net; AC/DC input with harmonic wave suppresser, stopping the harmonic wave polluting the electricity net, DC/AC convertor adopts  SPWM pulse width adjustment technique, IGBT power module, and output isolation transformer. Then the ups will output pure sine wave power supply which has stable frequency and voltage ,no noise and disturb. This series of UPS can satisfy many application environment because of the high load ability, good compatibility, large range of city input voltage and frequency, output no switch time and excellent generator with matching compatibility. Perfect protective circuit, which improve the stability and reliability.
