UPS System SALIENT FEATURES
True On - Line Pure Sinewave High Frequency PWM Inverter using IGBT
High frequency PWM technology using IGBT, provides high efficiency, low noise and faster transient response.
Computer Interface
The UPS can be interfaced with the host computer through Fibre Optic Cables. This enables local as well as remote monitoring of the UPS.
Modular Construction
The UPS is engineered with complete modularity. The power electronics is in the form of draw out modules having fork connectors for power and pluggable connectors for control. Modular construction facilitates easy maintenance, low MTTR and compact size.
Onsite Upgradability
These UPS system can be upgraded onsite
Options
- External battery rack for longer backup.
- Interactive software for remote monitoring with most popular operating systems.
- SNMP for remote monitoring.
- Green Power (Upto 30KVA): Unity input power factor, Input current distortion 7%, Compatibility with almost same capacity generator.
UPS Digital Manager
An alpha-numeric display with diaphragm switches provides an automatic cycling display informing the user on the operational status, active alarms and electrical parameters of the UPS, with priority to error messages. The display is automatically updated every 2 seconds, it can also be operated manually. The display can be programmed for different languages.
Auto Retransfer
The UPS has a unique feature of transferring the load automatically back to inverter as long as inverter is healthy and the load is within the capacity of the UPS.
The feature is very helpful for starting of loads, which draw starting in-rush current more than capacity of the UPS. The UPS goes to bypass on sensing over load and comes back on inverter supply automatically once the load current is settled to normal level.
