Cosel AC-DC Enclosed Power Supplies

Cosel offers multiple enclosure types: Metal enclosed - Robust aluminum or steel case for industrial environments, better EMI shielding and heat dissipation

Plastic enclosed - Lightweight, cost-effective, suitable for commercial applications

Chassis mount - U-channel or L-frame for mounting in equipment

DIN rail - For industrial panel mounting

Open frame - For integration into equipment enclosures. Enclosure selection depends on: Application environment, Safety requirements, Cooling method, Mounting constraints, Cost considerations. Metal enclosures provide best durability and EMC performance. Contact our FAE team for enclosure recommendations.

Use metal for industrial/harsh environments, plastic for commercial, DIN rail for panels. Contact us for recommendations.

Cosel enclosed power supplies use various cooling methods: Convection cooled - No fans, silent operation, suitable for lower power or moderate ambient

Forced air cooled - Internal fan for higher power density, temperature controlled

Conduction cooled - Heat transfer through mounting surface, for sealed enclosures

External fan - User-provided forced air for high-power applications. Cooling selection depends on: Power rating and efficiency, Ambient temperature, Enclosure design, Noise requirements, Reliability considerations. Convection cooled offers highest reliability (no fan wear). Forced air allows higher power density. Check datasheets for derating curves with different cooling methods.

Use convection for reliability, forced air for high power density. Check derating curves. Contact us for thermal design.

Cosel enclosed power supplies include comprehensive protection: Overcurrent protection (OCP) - Current limiting or hiccup mode

Overvoltage protection (OVP) - Shutdown or clamping to protect load

Overtemperature protection (OTP) - Shutdown on overheating with auto-recovery

Short circuit protection (SCP) - Continuous protection with auto-recovery

Input protection - Fuse and inrush current limiting. Protection ensures: Safe operation under fault conditions, Protection of connected equipment, Long product lifetime, System reliability. All protection features are tested during production. Check datasheets for specific protection thresholds and behavior.

All Cosel supplies include comprehensive protection. Check datasheets for specific thresholds. Contact us for protection design.

Cosel enclosed power supplies typically support multiple mounting orientations: Standard orientation - Base plate horizontal, terminals accessible

Side mounting - On vertical surface with appropriate derating

Upside down - Check specific model ratings for thermal performance. Orientation considerations: Heat rises - horizontal mounting optimizes natural convection

Terminal access - ensure safe access for wiring

Clearance - maintain minimum distances from surfaces

Derating - some orientations may require power derating. Check datasheets for orientation-specific ratings and mounting instructions. For unusual mounting requirements, contact our FAE team for guidance.

Standard horizontal mounting preferred. Check datasheets for other orientations. Contact us for unusual mounting.

Cosel enclosed power supplies offer excellent reliability: Typical MTBF: 200,000 to 500,000 hours at 25°C

High-reliability models: Up to 700,000+ hours

Calculated per Telcordia SR-332 or MIL-HDBK-217

Actual lifetime depends on operating conditions. Factors affecting reliability: Operating temperature - every 10°C increase halves lifetime

Load stress - operating at 50-70% rating improves reliability

Cooling effectiveness - adequate airflow extends life

Power quality - clean input power reduces stress. The 5-year warranty reflects confidence in reliability. For high-reliability applications, contact our FAE team for MTBF analysis and derating recommendations.

MTBF 200K-700K hours depending on model. Lower temperature improves reliability. Contact us for analysis.
