MasterElite
ERM 8-20kVA three/single phase
ERT 10-160kVA three/three-phase
The MasterElite range uses advanced double-conversion on-line (VFI) technology with a transformer isolated inverter output to support loads up to 160kVA (1MVA for the maximum parallel system). ERM models provide a single output from a three phase input. ERT models provide a three phase output.
- Advanced double-conversion on-line (VFI) technology (EN50091-3)with EMI filters and a transformer isolated inverter output
- High reliability : microprocessor controlled static and manual bypass facility
- IGBT based power electronics
- Extremely high short circuit current (2.8In)
- Parallel and redundant (N+1)operation (up to 6 units)
- Dual input option
- High level diagnostics : states, modes, measurements and alarms
- Built-in front panel LCD with scroll function, RS232 and signal contact ports
- Low power consumption and maintenance costs (MTTR 30minutes)
- Low cost and simplified installation including; calibration of the output voltage from the front panel keypad to allow for voltage drop down long cable runs
- Ability to place the UPS on any distribution network (neutral not required on rectifier input) using input isolation transformers
- Separation of the rectifier/bypass power supplies
- Powering from different sources without Galvanic isolation
- Built-in battery test facility (automatic and manual), temperature compensating charger and deep battery discharge protection
- Cold-start facility to allow the UPS to power up without a mains supply for security applications such as emergency lighting
