Input

  • Voltage : 170 – 270V Single Phase
  • Frequency : 50Hz +/- 1%
  • Rectifier : Automatic float cum boost charger, CVCC type.

Output

  • Voltage : 230 V + 3% with AVR
  • Frequency : 50Hz + 2%
  • Wave from : Sine Wave (with AVR)
  • Inverter Step approximate sine wave

Back up Time Options

15 min. -10 Hrs. with External Battery

Indications

  • Mains ON-(Glowing) i.e. UPS on mains
  • UPS ON ( Blinking)
    (a) Every 5 sec with Buzzer – UPS on battery backup
    (b) Every 5 sec with Buzzer – 75% of backup power utilized initiate save & quit operations
  • Fault (Glowing) System trip due to Over Load / Battery Low / Short / No Load Cut Off

Protections

  • Built in AVR gives regulated output against fluctuation
  • Fuse for over load & short circuit protection
  • Noise & spikes gets eliminated by EMI / RFI filter
  • Battery Low, Over & Under Voltage Protection.

Recharge Time
6 to 8 hours for 90% charge

Control Method

MOSFET based constant Voltage Current Limit

Transfer Time
Less Than Milliseconds

Environmental

  • Temperature : 0 to 40oC
  • Humidity : Ambient 30 to 90%

Meters

  • Voltmeter to read input & output

Controls

  • Mains : MCB
  • Load : MCB ( Optional )
  • Inverter : DPDT

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.
