MEAN WELL UHP-350-4.2 Switching Power Supply 252W 4.2V DC 60A Chassis Mount Fanless Design UHP-350-4.2

MEAN WELL UHP-350-4.2 is a switching power supply delivering 252 watts output power with a regulated 4.2V DC output at 60 amps. It features a compact chassis mount design with dimensions 220mm length, 62mm width, and 31mm height, making it a slim and low profile device. The fanless design provides silent operation using convection cooling for enhanced reliability and maintenance-free usage.

The power supply accepts a wide input voltage range from 90V AC minimum to 264V/370V DC maximum withstanding 300VAC surge input for 5 seconds, making it suitable for harsh industrial power environments. It includes an active power factor correction (PFC) circuit delivering high efficiency of 89% and supports a peak load capability of 150% for short durations to accommodate transient current demands.

Designed for robust industrial usage, the UHP-350-4.2 operates across a broad temperature range of -30°C to +70°C and can function reliably up to 5000 meters altitude. Protection features include short circuit, overload, over voltage, and over temperature safeguards to ensure device and load safety. The unit provides a DC OK active signal and options for redundancy configuration to maintain power reliability in mission-critical applications.

This model conforms to multiple international standards and approvals such as BSMI CNS143361, AS/NZS62368.1, CCCGB4943.1, CSA C22.2 No. 62368-1, EAC TP TC 00, IS 13252 (Part 1)/IEC 60950-1, TUV BS EN/EN 62368-1, and UL 62368-1, ensuring compliance and safety in global operations.

Applications include industrial automation machinery, control systems, mechanical and electrical equipment, electronic instruments, household appliances, and LED display panels where a reliable and efficient single output DC power source is required.

The power supply features a slim 31mm low profile fanless design for efficient convection cooling. Input voltage supports 90V AC minimum and up to 264V/370V DC maximum with surge resistance up to 300VAC for 5 seconds. It offers built-in active PFC function and 150% peak load capability for 100ms to handle transient loads.

Designed for wide temperature operation from -30°C to 70°C and altitude operation up to 5000 meters. Includes multiple protection mechanisms such as short circuit, overload, over voltage, and over temperature protection.

Provides LED power indication and optional DC OK active signal with redundancy function. Complies with international safety and efficiency standards including UL 62368-1 and TUV EN 62368-1 certifications. Ideal for industrial automation, control systems, mechanical and electrical equipment, LED display applications, and household appliances.
