1. S (D) GB series three (single) phase UPS.EPS special transformer is a multi-coil structure transformer with special structure and manufacturing process. The UPS and EPS special transformer series are designed for voltage conversion needs. They are made of imported cold-rolled silicon steel sheet stacks and high-temperature resistant high-insulation composite materials. The insulation grade is H grade, which effectively reduces the coil temperature through the coil air duct.
2. The product has the characteristics of high magnetic permeability, low loss, low noise, low temperature, radiation resistance and non-toxicity, maintenance-free, high environmental protection, etc. The special transformer has high input impedance, high space efficiency and high energy conversion efficiency, and perfectly matches UPS. Power supply, EPS power supply, variable frequency power supply (CFP), etc.
3. UPS and EPS special transformers are widely used in inverter power sources, such as uninterruptible power supply (UPS), emergency power supply (EPS), and variable frequency power supply (CFP).
Note: The leakage resistance value, wiring method and voltage value of UPS and EPS special transformers can be customized according to requirements.
4. The normal use conditions of S(D)GB series three (single) phase UPS.EPS special transformer are:
1), ambient temperature: -15 ° C - +50 ° C
2), altitude: <3000M
3) Relative humidity: < 95%
4) There are no gases, vapors, chemical deposits, dirt and other explosive and corrosive media that seriously affect the insulation of the transformer.
5) There is no serious vibration or bumps in the installation site.
