Multi-Level Switching (MLS) Technology UPS
MEDI’s MLS technology online UPS is a transformer-less UPS with front end PFC, harmonic reduction, common neutral, high efficiency three level inverter stage
Features:
- Input front end PFC to correct the current waveform to pure sine wave, power factor will be close to unity 0.99
- Very low harmonics < 4%
- Three level inverter stage results in very low switching loss and requires compact magnetics.
- Inverter stage and the PFC stage will process only the difference power which makes the efficiency very high and light weight.
- Efficiency >98%
- Absolute transformer-less design – no iron core transformer and no ferrite transformer used. Only light weight high frequency inductors are used. This results in very easy manufacturing.
- No isolation transformer needed because neutral is common
- Static bypass for uninterruptable bypass during hazard condition
- 4-level battery charging. Charging current up to 15A
- Suitable for all kinds of batteries – Lithium, lead acid etc
- 4-line LCD and graphic display
- Wifi connectivity with Android
- Temperature sensor and fan control
- Suitable for 110V
- Suitable for frequency converters – 50Hz input 60Hz / 400Hz output, 60Hz input 50Hz /400Hz output, 400Hz input 50Hz /60Hz output
