The TRM 3KVA Online UPS from TRM provides backup power essential to keeping your electronics powered should that power be interrupted. This power supply comes equipped with pure sine wave technology ensuring a constant flow of high quality clean power, while the full automatic voltage regulation feature adjusts the voltage keeping it within a safe operating range to reduce the risk of damage to connected devices. Along with enhanced voltage protection, you can monitor the UPS via the integrated LCD control panel.
When operating on battery, UPS outputs power with a pure sine wave that is identical to or cleaner than the power from the utility company grid, free of harmonic distortion and electrical noise, resulting in optimal line clarity.
The integrated LCD interface enables users to check UPS status, manage UPS setup and control, and run testing/battery calibration options. Status and log menus provide UPS vitals including input and output voltage levels, battery information, runtime estimates, load information, event and fault logging, and other system information.
Full AVR boost/buck technology stabilizes the AC voltage by increasing low voltages and decreasing high voltages to maintain a safe voltage level without switching to battery-mode. This conserves battery life, and delivers cleaner AC power to connected equipment.
►Decide the required size of the UPS (VA & Watts) to decide Power Capacity of the required UPS, you should decide which consumers should be protected and its power consumption in Amps, VA, or Watt.
►Decide the required Autonomy time (Back-up time) Autonomy time is the time that batteries are able to back-up operation and feed the load upon failure of utility power. Load consumption and size of UPS batteries dictate the back-up time.
►Decide the type of the UPS you need UPS's are roughly divided to three main classes. The Off Line (Stand-by) UPS is the simplest and the least expensive, then comes the Line Interactive type, which overcomes the major disadvantages inherent to the off-line unit, finally the Double Conversion On-Line UPS which provides the best power protection.
►Refine the deal at these stage you should already know the KVA rating of the UPS you intend to buy, the type of the UPS (Standby/Line Interactive/On-Line), the autonomy time needed, and the configuration (Stand alone or Redundant).
►Increase UPS capacity to allow for future expansion.
►Don't buy back up time that you don't need. Longer backup time does not mean better UPS.
►In case of Online units make sure you can add external batteries in future and that you can increase power by adding parallel units if expected.
►Don't buy any extras if you are not sure that they are needed for your application, Most can be added in the future whenever required.
►Make sure that the UPS performs automatic battery tests, warning whenever the batteries should be replaced.
►Backup time has no meaning if you don't consider the amount of UPS loading. Partial load increases the time the battery backs-up the equipment.
►When purchasing the UPS, make sure that after sales service is in good hands.
