Powerstar UPS Inc (CAGE 0zap8) manufactures rugged militarised uninterruptible power supplies (UPS) for shipboard, military and homeland defence. They supply Lockheed, General Dynamics, Electric Boat, BAE and many others with shipboard UPS from .5 to 20KVA.
Powerstar UPS is a US firm and has been manufacturing UPS since 1993 with equipment on ships from US, Denmark, Australia, Canada, Norway, & Taiwan.
High-quality motherboards for shipboard use
Powerstar UPS uses only the latest high-quality motherboards from either APC™ or Liebert™; two of the largest, most recognised manufacturers of commercial off-the-shelf (COTS) UPS systems in the world.
The company converts these units for shipboard use, ruggedises them to military grade, and customises them to fit the needs of its customer.
Low-cost shipboard UPS
Powerstar offers small inexpensive 330W-425W brick-shaped UPS (PS502 line) in either 120V or 230V.
These units can be used for a PC, printer or any low-power requirement.
The units are efficient and weigh less than 7kg. They are available with ten-year battery pack and are NSN registered.
The PS502 series connects via USB to inform the PC of UPS alarms and alerts to when to begin graceful shutdown upon loss of ACMAINS.
UPS for shock- isolated equipment racks
The majority of Powerstar’s PS3000 and PS6000 lines can be ruggedised to meet MIL-810F or G, or MIL-S-901D grade B. These all use the original equipment manufacturer (OEM) chassis. The products have 1U, 2U rack mount heights and 750VA- 3KVA capacity. On military ships, these can often be used in MILSPEC shock absorbing isolated equipment racks. There are also 230V models available. These units can have MS threaded locking style connectors added as well.
Rugged stainless steel hull mounts
Powerstar has a well-established line of rugged mini-tower shaped models that are hull mounted:
- PS1504SS 1.5KVA 984W output, 8.6in tall x 17.6in deep MIL-S-901D/A All Stainless cabinet
- PS2201SS 2KVA 1980W output 17in tall x 22in contains double the battery capacity of the PS1504. MIL-S-901D/A and MIL-std-461 The all stainless cabinet is popular on the MCM class due to its non-magnetic cabinet.
This hull mount series is offered with bolt-down / weld-down steel mounting platforms for secure bolt-down mounting, but easy removal.
The firm offers five-year, ten-year, and 12-year extremely rugged battery packs for these models. Many UPS are NSN registered. These units use the company’s 304-grade gleaming stainless-steel chassis to meet the MIL-S-901D tests.
Powerstar’s mounting platforms have a steel base that can be bolted or welded to the deck and bolt-down steel straps surrounding the supply. To reduce costs, the firm can also offer these units with their OEM cabinets if it not required to meet the high shock tests.
The PS2201r3 offers electromagnetic interference (EMI) gasketing, shielding and filtering for MIL-std-461. These all use the APC brand electronics.

The connector area is protected as it is next to the 5in protrusion containing the isolation transformer.
The 120G rated input circuit breaker is front-mounted and finger guard-protected. PS6000r2isoAh adds in the ten-year life battery pack.
Options are also available for Dry Contact signaling PS9613 card, PS9630 Ethernet card or PS9620 Legacy card (simulates an SUA style DB9 simple signaling port).
PS3300LCS is a MIL-S-901D Grade A tested unit. The 3KVA /2700W isolated UPS is a true online double conversion style UPS. Powerstar uses a 3u x 24in d stainless-steel cabinet that also houses the toroid isolation transformer. It produces very clean and regulated output power and uses Liebert brand electronics. This unit is equipped with an Inrush surge suppressor.
The PS3300LCS can be used with the PS9059 Ethernet network card to command many computers for graceful shutdown procedure when the battery pack is depleted. The firm also has many add-on 2u x 24in d battery pack options. This UPS was built for the Littoral Combat Ships but is now used on many ships in the US, UK, Australia and Canada for defence.
