UPS
ONLINE-UPS
In this type of UPS, the system always remains on battery, whether mains ac is present or not. When mains ac is present, it provides power to DC supply of inverter section as well as charges the battery simultaneously. When mains ac is not present, it will run the connected load till the battery has a recommended dischargeable level.
Features:
- Excellent dynamic response for step load change
- Smooth and silent operation
- Easy to install, use and maintain
- Constant current and Constant Voltage Battery Charger.
- Fully isolation form input to output
- Ultimate protection against all power line disturbances

OFFLINE-UPS
In this system, the load is normally on Mains power supply. This may be regulated to some extent by an in-built voltage regulator. When the Mains power fails, the inverter takes over and supplies power to the load while draining the battery.
Features:
- Surge and Spike protection
- Overload, Low battery, Over Charge
and Short Circuit Protection - Micro Controller based design for
optimum performance and reliability
- Wide input voltage range.
- Efficient battery Charger
- Very fast change over with
output Voltage detection
