Ruggedized Industrial Power Supplies for Harsh Operating Environments

AJ's Power Source Inc. (AJPS) is an industry-leading manufacturer of heavy-duty industrial AC-DC and DC-DC power supplies. Industrial applications present severe environmental and electrical challenges—ranging from dust, debris, and extreme vibration to sub-zero temperatures and fully submersible outdoor operating conditions.

Whether you require a standard COTS unit, a modified power chassis with short lead times, or a clean-sheet custom design for complex industrial machinery, our U.S. power engineering team delivers high MTBF platforms tailored to your exact operational requirements.

  • Universal AC input with Power Factor Correction (PFC)
  • Wide operating temperature range (-40°C to +85°C options)
  • High transient surge immunity & internal noise suppression
  • Conduction, convection, and forced-air cooling options

Buyer Knowledge Base

Frequently Asked Questions for Procurement Teams

Our industrial power supplies are designed to meet or exceed global standards including UL, CE, TUV, CSA, IEC, and EN safety and electromagnetic compatibility (EMC) regulations. Full compliance testing documentation can be supplied for qualification packages.

Yes. We offer fully custom and modified-COTS power solutions tailored to specific input/output voltages, environmental sealing (IP65/IP67), extended temperature ranges (-40°C to +85°C), custom connectors, and tailored mounting brackets.

We manufacture rack mount (1U to 4U), DIN rail mount, panel mount, standalone tabletop, inline sealed units, hot-swappable modular systems, and custom chassis tailored to plant or machinery integration needs.

By leveraging proven, field-tested internal circuit topologies and mechanical housings, modified-COTS designs bypass lengthy clean-sheet design phases. This significantly reduces NRE development costs and accelerates time-to-market.
