The pragmatic choice for 8–30 kVA vessel projects

Small loads are well served by 9PX Marine. Once you are powering the whole bridge, engine-room monitoring or the main communications rack, past 8 kVA you are in 9155 territory:

  • Parallel expansion — hot-sync paralleling supports four units. Add capacity when you need it, or build N+1 redundancy.
  • Generator friendly — a 0.99 input power factor and low harmonics put a gentler load on the ship's generator, without the embarrassment of a generator alarm every time the UPS starts.
  • Marine compliance — IEC 60945 and IP22 are routine acceptance requirements on vessel projects, and this unit meets them as standard.

Three things to confirm when you configure

  1. Input configuration — single-in/single-out (1:1) or three-in/single-out (3:1). It follows from the ship's distribution system and must be settled before order.
  2. Runtime — vessel projects usually specify a long discharge. External battery capacity and its location need planning early.
  3. Paralleling — whether you need redundancy (N+1) or capacity expansion changes the unit count and the wiring design.

Key features

  • Complies with IEC 60945 for marine electronic equipment; internal components resist salt-spray corrosion
  • Main cabinet rated IP22 for damp, humid spaces
  • 8–30 kVA, single-in/single-out or three-in/single-out, output 220/230/240 V
  • Static bypass plus a manual bypass switch, so maintenance does not mean dropping the load
  • Input power factor up to 0.99 with low harmonics — it works with a ship's generator rather than against it
  • ABM battery management extends battery life
  • Hot-sync parallel technology, up to four units, so N+1 redundancy is a design option
  • Compact footprint with a clear LCD interface
