Description
The topology is VFI-SS-111 online with galvanic isolation on the inverter side. The transformer separates the load from the battery circuit and from any DC component, which medical and industrial sites with sensitive controls appreciate. Soft start of the rectifier avoids an inrush when the supply moves from mains to a generator, so the diesel set does not need a large oversize margin. Up to 8 UPS run in parallel with a distributed or centralized bypass. The UGS option synchronizes UPS groups and PSJ joins parallel systems, which is needed with two independent supply busbars. Batteries can be vented lead-acid, VRLA AGM, GEL, NiCd or Li-ion, and supercapacitors or flywheels also fit. Battery Care manages charging to extend battery life, and ECS mode cuts losses.
How to choose
First decide on the output. The 3:3 configuration gives a three-phase output at 10–200 kVA, while 3:1 serves single-phase loads up to 120 kVA. If the load goes past 200 kVA and isolation is still required, look at the Master HP at 100–600 kVA or the Master HE at 100–800 kVA/kW. For 250–800 kVA with no transformer requirement, the transformerless NextEnergy NXE fits with up to 97 % online efficiency. For an industrial 220 V DC bus there is the Master Industrial at 30, 40, 60 and 80 kVA.

FAQ
How many Master MPS units can be paralleled?
Up to 8 units, with either a distributed or a centralized bypass.
What power does the single-phase output Master MPS have?
In 3:1 configuration the models cover 10–120 kVA.
Does the Master MPS work well on a generator?
Yes, rectifier soft start and transformer isolation make generator operation easier. The 3:3 models come in 10–200 kVA.
Where is the isolating transformer in the Master MPS?
At the inverter output. The load is galvanically separated from the DC link and the battery.
How are two groups of Master MPS units synchronized?
The UGS option synchronizes the groups, and the PSJ option joins parallel systems.
