Shipboard UPS Powerstar(the Best) vs. APC  new                 


Powerstar Inc. expands in the APC lineup of Smart-UPS for Shipboard use  with  more options,and they are stainless steel from Powerstar..  APC offers a limited lineup of X93 style units.  Powerstar builds most any of the other land based APC units into a Ruggedized and/or Shipboard version inclluding the surta version, the smt version and the smx version.  Powerstar has been building shipboard versions of APC units since 1993. We have thousands out there. We ruggedize units to meet the shock and vibration requirements of the Naval environment including mil 901,167,461, and mil 1399.  You can get APC electronics engineered Motherboards for reliability and use the Powerchute software non-customized for your Naval or rugged terrestrial needs.   We have now added the new SMX and SMT rackmount series.

Safely Launch Shipboard Electronics with Smart-UPS. The Naval Safety Center reports most commercial electric equipment is unsuitable for use in the Navy's ungrounded shipboard power system (Ref: COMNAVSAFECEN NORFOLK VA 280836FEB94). As the market leader in the UPS industry, American Power Conversion decided to resolve the safety issue, and develop the Smart-UPS Shipboard Series. This is a modified COTS (commercial-off-the-shelf) UPS specifically designed to operate safely aboard ships and submarines. NSWCCD-SSES Philadelphia tested this unit to ensure it met all the navy shipboard electrical safety standards. Additionally, this unit meets DC resistance requirements IAW NSTM Chapter 300 and MIP 3000. (NAVSURFWARCEN 151800ZNOV94)

The Smart-UPS Shipboard Series includes a double-pole circuit breaker that will protect lines from overload and a double-pole power switch to insure the attached load is completely removed from the input power lines. These are necessary because a ship generates Delta power causing both power lines to be "hot". 

Powerstar Inc. supplies:

·         Built in Isolation transformers on optional units

·         304 grade Stainless steel chassis (fully welded corners with countersunk panel screws built by American Craftsmen)optional

·         Additional shock and vibration hardening  mil 901

·         Independent Laboratory Tested units for Mil-STD-901D grade A, Mil-STD-167, Mil-STD-1399, Mil-STD-461, MIL 810F etc.  thru nulabs , a navy test lab.

·         Powerstar does not add a switch to the output power; eliminating a possible failure point in the APC X93 design.

·         Powerstar offers Premium extended temperature range, long life batteries (up to double the life of APC cells) and the Xseries.. These cells have been tested and accepted by SPAWAR.

·         Military Specification  thread-on connectors like the MS3102 for input and output connections

·         Shock tested circuit breakers rated to over 120G.  These can be front mounted on many units with Government approved finger guards.

·         Specially designed cabinets for tough size limits imposed on the engineers. For example our PS6003 2+2 3KVA only 18” deep or our PS6000-1 15” deep 1.5KVA UPS,shallow depth

·         Don’t need full ruggedization but better than COTS? We can build to MIL-STD-901D grade B as well. We can supply standard units that can surpass the grade B requirement. These are great for mounting in Shock absorbing racks.

·         Powerstar also uses the Liebert brand UPS for the PS3xxx series. These True-online UPS offer superior efficiency specs for Double conversion designs.  We can ruggedize their existing package and modify for Shipboard use or use their electronics in a fully ruggedized and specially shielded Powerstar exclusive chassis as the PS3300LCS or PS3300Elgar. The Elgar is a unit wired to be used with a Elgar PDU as used in COBLU.
