Description
The 5–6 kVA models run 1:1, while the 8–10 kVA models accept single-phase or three-phase input (1:1 or 3:1), handy when the panel only has a three-phase feed. A three-level inverter and VFI-SS-111 topology give up to 95 % efficiency online and 98 % in ECO. Besides ON LINE and ECO there are SMART ACTIVE, STANDBY OFF and a 50/60 Hz frequency converter mode. The unit carries 110 % overload continuously, 130 % for 1 h and 150 % for 10 min, so pump and compressor starting currents pass without a transfer to bypass. Up to 3 UPS run in parallel. Internal batteries are VRLA AGM, and ER versions come without them and with a 6 A charger for external battery cabinets. The 250×698×500 mm housing passes a standard door and rolls to its place.
How to choose
Size the unit for total load with margin for starting currents. If the panel only offers three phases, you need the 8 or 10 kVA model with 3:1 input. For long runtime choose an ER version with an external battery cabinet. On ships and offshore platforms, the Sentinel Dual Marine at 6 and 10 kVA/kW with DNV type approval takes this series' place. For loads from 10 kVA with three-phase output, the Master MPS at 10–200 kVA fits, and emergency lighting to EN 50171 uses the CSS Sentinel Tower version at 3–5 kVA.
