Digital Home PQ 250
PQ 250 is a multi purpose Digital Home UPS with a power output of 250VA / 250W. It is focused towards customers who want to run smaller load and have limited budget. It uses a 40 Ah / 60 Ah car or tractor battery which is already available in many homes and charges using 5A DC current. Also, it is capable of running computers without re-booting during power failure. This makes is suitable for computer backup applications at very low cost and for long backup time. Additionally, there is an optional MPPT Solar charger which charges the battery 30% faster using a 75W Solar panel.
 
Applications
• Shops
• Hostels
• Guest House
• Homes
• Internet café

Advanced Technology

  Micro controller based PWM technology for regulated output.
  Three stage, (Boost, absorption and float stages) precision regulated charging for long battery life.  During charging the rate of rise of the battery voltage is monitored and the charging current / terminal voltage are controlled precisely to prevent battery from ‘gassing’. This technique prolongs battery life and also eliminates the need to top up the battery (i.e. fill it with distilled water) frequently.
  Low battery warning and cut off to prevent the battery getting deep discharged.
  Very fast changeover (typically 10 msec) to ensure that your computer does not reboot during changeover.
  Mains high voltage protection. Whenever, the mains voltage is above a safe value, the mains input is cut off to protect your costly appliances from damage. This high voltage protection works even when the back up switch is off.
  Filter circuit at the output to minimize humming noise in electrical appliances like fans.
  Charges the battery on generator also. Input frequency range is 45 Hz to 55 Hz. Only when the frequency goes outside these limits, the Home UPS changes to back-up mode.
  Ability to withstand PC or TV turn on current surge without indicating ‘Overload’.
  Automatic holiday mode reduces current from the battery when there is no load at the output for a long period of time. The battery is kept fully charged to greet you with “Roshni aapke vishwas ki” when you come back from your holidays.
 
 
 
 
  Special microcontroller for Inva tubular batteries (High final charging voltage) to enable them to be fully charged.
 
Notes:
1.The above calculations are indicative values only. Actual load may vary depending on the make and model of the appliance used.
2. When PC is running, it is not recommended to turn on the TV as it may reboot the PC.
 
Back-up time and charging time estimates:
With High Charging setting is selected, the estimates of the back-up time and charging time are as under:
 
 
Note:
1.The above table shows that if you are planning to run the Home UPS at full load, then this model is suitable for Power Cut Duration (PCD) of total 3 and a half hours in a day (24 hours). For half load, they can support PCD of about 7 hours / day.
2. Note that these durations are indicative figures for fresh batteries.
3. Pepteller recommends Inva-tubular (special batteries for inverter / UPS application supporting deep discharge) batteries from a reputed make like Exide, Tata Green etc.
 
 
Note:

In our continual endeavor for improvement, we reserve the right to change specifications at any time without notice.
