3-5kW 48 Vdc
Double Conversion Online (VFI)
This is a multi-function UPS, combining functions of inverter and battery charger to offer uninterruptible power support with portable size. Its comprehensive LCD display offers user-configurable and easy accessible button operation such as battery charging current, AC charger priority and acceptable input voltage based on different applications.
STC comes in nominal power rating of 3,000VA and 5,000VA. It is designed to provide conditioned power to microcomputers and other sensitive electronic equipment. When it is generated, alternating current is clean and stable. However, during transmission and distribution it may be subject to voltage sags, spikes and complete power failure that may interrupt computer operations, cause data loss and even damage equipment. The UPS protects equipment from these disturbances. The UPS is a compact, on-line UPS. An on-line UPS continuously conditions and regulates its output voltage, whether utility power is present or not. It supplies connected equipment with clean sinewave power. Sensitive electronic equipment operates best from sine-wave power. For ease of use, the UPS features a LCD display to indicate all information for UPS, and provide kinds of function buttons.
The UPS is programmed to restart automatically when the mains returns after switching off due to end of backup time following prolonged power failure.
STC Series comes with an expansion slot for optional communication board which make it compatible with the main communication option: SNMP and AS40.
