- Voltage : 230 V Single Phase + 19% – 15% or 415 V Three Phase +/- 15%
- Frequency : 50Hz +/- 6%
- Rectifier : Automatic float cum boost charger, CVCC type.
Output Performance
- Voltage : 230 V Single Phase + 1% or 400 V Three +/- 1%
- Frequency : 50Hz +/- 0.5Hz
- Wave from : Sine Wave
Distortion
THD less than 5% with no single harmonic greater than % on linear load, Power Factor : 0.8 lagging to unity.
Inverter Side
- Inverter Efficiency
- On full load better than 85%
- Control Method : Sinusoidal PWM control
- Circuit Method : True on Line PWM UPS Zero Transfer Time
Normal DC Voltage
- 48 V DC / 60 V DC / 120 V DC
- 144 V DC / 240 V DC / 300 V DC
- Creast Factor : Better then 2.5
Environmental
- Cooling : Forced air cooled.
- Temperature : 0 – 50 o C Ambient
- Humidity : 95% RH non condensing
- Acoustic Noise : Less than 60db at 2mts. from the cubicle.
Static Bypass : ( Optional )
Adequately rated solid state switch which will transfer load from UPS to Mains within 10 Mesc. (synchronized ) 20 Msec. (unsynchronized) to avoid any damage to loads.
