Powerstar since 1993 releases the short tower shaped PS503-1000VA 900W Shipboard UPS. This is a Low Cost Solution for UPS needs on board any ship. $1299. This is not a stripped down unit. It has all the features of its big brothers using high quality Liebert Electronics. True Online Double Conversion so there is NO switchover time. True Sine wave output- no humming or interference created by a Stepped Square Wave output. Frequency converting if needed. Built in Automatic Bypass circuit should the inverter fail due to overload or other problem to keep your systems with maximum Up time. Slot for SNMP Ethernet Card. Emergency Power Off Contacts. 6 outlets. A great Power Factor. Built to MIL-Std-1399. Variable speed fan. Optional Powerstar solid steel optional mounting foundation is available. Additional ruggedization is also available to bring this unit to MIL-STD901D-A and MIL-STD-167 compliance. Powerstar Premium batteries also available (8-10 year life at 25°C)
Protect the sailors, use a properly designed UPS onboard to reduce shock hazards. Use on deepwater platforms, cruise ships, drilling rigs. We can also offer Line Isolation transformers to reduce or eliminate shock hazard from a sailor touching an energized wire while standing on a wet metal deck. Read about shipboard power here.
What is this unit missing? An external battery connector for additional battery cabinets- thats it!
If you need larger runtimes than the PS503, look to the PS3070rm2u or the PS3100rm2u with all the same features but has that external battery connector for up to 4 additional 2u trays. The PS3070 or PS3100 are convertibles and can be tower or rack. See its full description in our catalog.
