Install as either a freestanding tower or 2U rackmount UPS. Simply plug and play, no complicated setup. Enhanced inverter delivers 0.9 power factor and 92% efficiency. Easy maintenance with hot-swappable batteries. The doubly-versatile Sentinel Dual (Low Power) combines installation flexibility with fantastic functionality and ease of maintenance. The single-phase UPS comes in a variety of 4 power ratings (1000-1500-2200-3000 VA).
Reduced Management Costs
SENTINEL DUAL can be programmed remotely via software or set manually from the front mimic panel to operate in a range of energy saving operating modes:
- On Line: maximum power protection and output voltage waveform quality
- ECO: to increase operating efficiency to 98% and provide line interactive protection
- Smart Active: with the UPS selecting automatically its operating mode – ECO or On-Line dependent upon the reliability and quality of the local mains power supply.
- Backup: for emergencies only with the UPS only operating when mains power fails
- Frequency converter: from 50 to 60Hz or 60 to 50Hz.
Advanced Communication
SENTINEL DUAL offers maximum flexibility for integrations with any communication system.
