Powerstar UPS PS1504 New Shipboard 1.5KVA Our warhorse, the PS1503 and PS1503-H have been used in 1000’s of jobs. The replacement unit has arrived. Our PS1504 with our shipboard modifications, Stainless steel, louvered wrapper and Full ruggedization if you like is better than the previous gen. Ask for the PS1504H and you get a MIL-S-901D-gradeA and Mil-std-167 shock / vibration rated unit with Powerstar Premium batteries And it runs APC Powerchute© software for monitoring.

There are many variations of this shipboard model. The standard PS1500SMT uses a high impact styrene front panel and black painted metal cabinet.  It is a slightly different cabinet size than the old PS1503 (SUA1500) cabinet. For those that need an identical cabinet size to the PS1503 we offer the PS1504- The PS1504 uses a cabinet made by Powerstar in 304 grade Stainless steel (see picture) . This cabinet is Fit, Form, Function identical to the previous gen. PS1503/ PS1503SS.  Please see the PS9620 Legacy card if you are using the DB9 port with Hi/ Lo alarm signaling for complete compatibility.

The PS1504 offers a 2 line Alphanumeric text readout on an LCD display on the front panel. It offers the new Microlink protocol on its Serial communication ports (USB or RS232) which can pass more information to the Powerchute console. Same great automatic configuration with Windows XP, Vista, Win 7 and above. Just connect the USB and Windows installs its own drivers to use a UPS.

Please note LMCO uses a PS1503hmb which is the GradeA Rugged SMT version.  This is a modern SMT series unit, with the old model designator.

Mounting (option)

Powerstar builds mounting plates for hull or deck mounting. Padded steel plate with padded straps (hoops) wrap around UPS and hold it securely to the plate. The plate can be bolted or welded in place.

PS1504 Mounting foundation for the standard PS1504 with Styrene front panel.

PS1504SSA Mounting Foundation  For the Grade A unit with the Powerstar made cabinet. This also fits the previous generation PS1503SS

Option for PS1504 standard unit ;



  • SS Stainless steel louvered upper case. The standard non ruggedized PS1500 uses a rugged but styrene front panel and painted steel chassis.
  • Conformal Coating for the circuit board; additional protection from moisture, dust, dirt on the electronic circuitry.  Please call for pricing.
  • -Tilt Front control panel tilted upward.  This option tilts the front panel upward ~30° for improved visibility of the Text Readout.  Note: the  Orange and Red LED Warning lamps are visible at up to 160° without the tilted panel.  The Warning lamps will alert a tech (as will the Audible BEEP)  to read the Text readout to observe the Alarm Text.
  • -MB Master Bypass switch- connects the input power directly to outlets. This UPS can also be supplied with a MB Master Bypass switch. The MB switches the input power directly to the output ports. This bypasses the entire UPS in case of total unit failure. (The Circuit Breaker is still left in the circuit in bypass mode. ) The MB switch is a rotary knob with Green and Red lamp indicators showing switch position. $350+
  • -ISO An Input Isolation transformer can be added either remotely or attached to the top of this unit making it 6″ taller. 2KVA and field proven in our other product lines. This transformer can also be used on alternate input voltages to step-down input VAC.
  • Step down autoformers may be attached similar to -ISO. These do not provide isolation.
  • The SmartSlot can accept 1 of these cards:
  • PS9620 Legacy DB9 serial port fills the one available Smart Slot. The Legacy card emulates the previous generation DB9 Smart UPS port including the APC style ‘Dumb’ mode  Hi/LO signaling to show ‘Loss of MAINS’ and ‘Low Battery’ $60+
  • PS9630 SNMP Ethernet port- Monitor this unit via Ethernet and PowerChute® software. Shut down PC via Ethernet. $350+
  • PS9631 Ethernet & Temperature / Humidity* sensor.  Report the temperature of the room the UPS is located in and report it back to the console running
  • PowerChute®. This card also contains dry contacts for signaling outputs (Loss of MAINS, etc) and Inputs ie, Emergency shut down. $600+
  • PS9613 Dry Contact card. Inputs and Outputs. Shut down the UPS with an external contact closure low current low voltage. A source is available.  Also signal external devices of Loss of MAINS, Low Battery, Unit ALARM (electronics failure, battery did not pass test, etc)  This signaling is all performed with simple DC closures. <35Ma. $600+
