Military Rackmount Power Supplies
Configurable 1U, 2U, and 3U AC to DC and DC to DC rackmount power systems designed for tactical shelters, transit cases, and ground control stations.
AJ's Power Source Inc. (AJPS) is a premier original equipment manufacturer (OEM) delivering high-reliability ground, naval, and airborne avionics military power supplies. Serving U.S. Department of Defense prime contractors, government procurement agencies, and international defense integrators for over 35 years, our platforms are engineered to solve complex thermal, electrical, and mechanical challenges.
Whether you require standard COTS (Commercial Off-The-Shelf), Modified COTS (MOTS), or full custom clean-sheet designs, AJPS provides robust power conversion, uninterruptible power backup, and intelligent power distribution equipment with industry-leading Mean Time Between Failures (MTBF).
Explore our field-proven product families engineered specifically for defense vehicles, tactical shelters, naval vessels, and airborne mission systems.
Configurable 1U, 2U, and 3U AC to DC and DC to DC rackmount power systems designed for tactical shelters, transit cases, and ground control stations.
High and low output DC-DC converters (2000W–2500W+) engineered with MIL-STD-1275 surge, spike, and reverse polarity protection for ground armor.
Compact 400W and 800W pure sine-wave DC-AC power inverters converting direct current vehicle/battery power into stable alternating current for field electronics.
1U to 4U online double-conversion rugged UPS platforms ranging from 800W to 3000VA featuring hot-swappable battery modules and harsh environment conditioning.
AC and DC rackmount and circular-connector power distribution units featuring per-branch circuit protection, remote status monitoring, and rugged interconnects.
Rugged COTS AC-AC step-up and step-down isolation transformers for 50Hz, 60Hz, and 400Hz frequency applications across defense systems.
Fault-tolerant, hot-swappable AC-DC and DC-DC power modules designed for continuous zero-downtime mission systems and redundant server racks.
Universal input power line conditioners designed to clean dirty field power, suppress high-voltage transients, and maintain voltage stability under heavy load surges.
IP65 and IP67 sealed, fully potted, submersible AC-DC and DC-DC supplies built with MIL-DTL-38999 circular connectors for extreme outdoor environments.
Our experienced engineering team mitigates program risk by integrating military standard compliance directly into initial schematic design, thermal modeling, and component selection.
| Military Standard | Compliance Scope | Engineering Design Impact |
|---|---|---|
| MIL-STD-810 | Environmental Engineering Considerations | Thermal derating (-40°C to +85°C), shock/vibration isolation, conformal coating, salt-fog resistance, altitude & humidity protection. |
| MIL-STD-461 | Control of Electromagnetic Interference (EMI) | Integrated multi-stage input filtering, shielded topologies, bonded chassis returns for CE101, CE102, CS101, RE101, RE102 pre-compliance. |
| MIL-STD-1275 | 28 VDC Electrical Input for Military Vehicles | Active surge/spike clamping, cranking drop-out hold-up circuitry, load dump protection, reverse polarity survivability. |
| MIL-STD-1399 (Sec. 300) | Shipboard Electrical Power Interface | 60 Hz / 400 Hz harmonic management, voltage/frequency transient tolerance, tight regulation on unbalanced naval buses. |
