In high-reliability defense, aerospace, and heavy industrial domains, power electronics represent the operational backbone of tactical ground vehicles, unmanned aerial vehicles (UAVs), naval surveillance radar, and remote telemetry stations. Standard Commercial-Off-The-Shelf (COTS) power converters consistently fail to withstand the unique operational stresses present in harsh ambient environments such as those found throughout the Sultanate of Oman—where ambient temperatures frequently exceed +50°C, airborne fine silica sand causes thermal insulations, and erratic microgrid electrical transients degrade standard power stages.
Military Commercial-Off-The-Shelf (MIL-COTS) DC-DC converters bridge the vital gap between pure industrial-grade modules and custom full-spec military hardware. By combining proven, high-volume manufacturing lines with rigorous environmental screening, high-density planar magnetics, and integrated transient voltage suppression (TVS) architecture, OEM MIL-COTS power modules deliver exceptional power density, rapid qualification timelines, and significant lifecycle cost optimization.
Information Gain Insight: Modern defense systems in Oman require DC-DC converters engineered specifically for conduction cooling via heavy aluminum baseplates, eliminated electrolytic capacitors (utilizing multi-layer ceramic capacitance arrays instead), and potted hermetic encapsulation to prevent silica particle ingress and high-humidity salt spray degradation along coastal zones like Salalah and Sohar.
Our custom manufacturing capability provides defense prime contractors, system integrators, and OEM equipment engineers in Oman with tailored DC-DC power architectures. Whether converting 28VDC vehicle power buses governed by MIL-STD-1275D/E, 270VDC high-voltage distribution rails for airborne radar, or wide 4:1 input ranges (9V–36V / 18V–75V) for localized tactical communication shelters, our engineering team modifies standard platforms or builds clean-sheet topology systems optimized for your exact load profile.
Oman's unique geographic diversity and strategic defense posture demand tailored power conversion topologies. From the extreme thermal envelopes of the Rub' al Khali desert to naval maritime ops in the Strait of Hormuz, OEM MIL-COTS DC-DC modules are customized to solve specific operational challenges across local sectors:
Conduction-cooled 28V input DC-DC converters featuring integrated active surge stoppers designed to absorb heavy 100V/500ms surges and 250V spikes compliant with MIL-STD-1275E for armored personnel carriers and mobile command units operating in desert terrain.
Conformally coated and silicone-potted DC-DC converter bricks designed to resist high humidity, salt fog, and coastal corrosion. Providing ultra-low output ripple (<10mV p-p) for sensitive digital signal processors and phased-array radar electronics.
Wide input (18V-75V DC) ultra-rugged DC-DC modules used in remote SCADA cabinets, oilfield cathodic protection controllers, and wellhead monitoring stations operating under unassisted continuous high thermal ambient conditions.
Designing power electronics for deployment in the Middle East requires strict adherence to international military and industrial compliance standards. When delivering OEM MIL-COTS DC-DC converters to Oman's industrial and defense integrators, every design undergoes rigorous qualification testing across four major vectors:
Ground vehicles experience severe electrical disturbances during heavy engine cranking, battery disconnects, and inductive load switching. Our MIL-COTS DC-DC modules incorporate active clamping sub-circuits and transient voltage suppression networks that handle continuous 28V input rails while withstanding +100V surges for 500ms and ±250V transient spikes without output interruption or component degradation.
High-frequency switched-mode power supplies can introduce conducted and radiated interference into sensitive communications gear. By integrating hybrid passive/active line filters, custom differential-mode inductors, and 6-sided metal shielding enclosures, our converters meet strict CE102, CS101, RE102, and RS103 limits under MIL-STD-461G.
Direct air cooling via fans is frequently impractical in desert environments due to dust clogging and fan bearing failure. We utilize zero-fan conduction cooling technology. Power devices (MOSFETs, GaN FETs, and Schottky Rectifiers) are mounted directly to heavy copper-clad substrates bonded to an aluminum baseplate. This architecture allows full rated output power up to +85°C baseplate temperature and operational survival up to +105°C baseplate temperatures.

The Sultanate of Oman is undergoing a transformative economic evolution driven by Oman Vision 2040. A fundamental pillar of this framework is industrial diversification, expansion of local defense maintenance, repair, and overhaul (MRO) facilities, and increasing In-Country Value (ICV) requirements for public infrastructure and defense procurement projects.
As Omani manufacturing hubs in Muscat (Rusayl Industrial Estate), Sohar Freezone, and Salalah Industrial City scale up assembly capabilities, local systems integrators require reliable OEM power supply partners capable of providing flexible manufacturing models. Our enterprise supports local Omani integrators through:
Our modules utilize high-efficiency planar transformers and wide bandgap GaN/SiC semiconductors that minimize internal power dissipation. Engineered with heavy aluminum baseplates, they transfer heat directly into heat sinks or chassis metalwork via conduction, operating reliably up to +105°C baseplate temperatures without requiring active cooling fans.
Yes. As an OEM/ODM manufacturer, we specialize in mechanical and electrical footprint matching. Whether you require a standard half-brick/full-brick configuration, custom 3U/6U VPX power cards, or rugged metal chassis enclosures, we can tailor the physical geometry to drop directly into your system backplane.
Absolutely. We offer integrated transient surge suppression modules that clamp high-voltage spikes up to ±250V and sustain continuous low/high voltage limits defined in MIL-STD-1275E, guaranteeing uninterrupted 24V or 28V regulated DC output to critical payload electronics.
Every shipment is delivered with a Certificate of Conformance (CoC), individual serial number burn-in test results, RoHS/REACH compliance declarations, and detailed thermal/electrical specification datasheets. Full MIL-STD qualification test reports can be supplied upon request.
We provide ultra-wide input ranges tailored to your source power: 9V–36VDC (4:1) and 18V–75VDC (4:1) for battery/industrial systems, 18V–36VDC for 28V military buses, and high-voltage DC inputs (180V–375VDC or up to 800VDC) for specialized radar and electric vehicle power distribution rails.
All internal circuitry is protected using vacuum silicone potting or thick conformal coating meeting IPC-CC-830 standards. This completely seals components against airborne fine sand (silica dust), salt spray humidity, condensation, and structural mechanical shock/vibration compliant with MIL-STD-810H.
With over three decades of power conversion heritage (tracing legacy engineering strengths back to Powerstax PLC and advanced high-voltage research divisions), our manufacturing facility delivers world-class power solutions tailored for high-stakes environments. We don't just supply standard power supplies—we partner with engineering teams from initial electrical topology simulation through EMI debugging, thermal prototyping, and mass manufacturing.
Every single module undergoes 100% full-load burn-in testing under elevated temperature conditions before leaving our factory. Our commitment to zero-defect quality, combined with agile lead times and deep expertise in MIL-STD qualification, makes us the premier OEM power supply manufacturing partner for defense, marine, energy, and aerospace programs across the Sultanate of Oman and the wider GCC region.
