MEAN WELL PT-65A Fonte de alimentação open-frame 65W com saída tripla

Industrial and embedded systems often demand a compact, reliable power source that delivers multiple DC voltages without adding bulk or noise. The MEAN WELL PT-65A answers that need with a 65-watt open frame switching power supply, offering +5V, +12V, and -12V outputs from a universal AC input. Its free-air convection cooling eliminates fan noise and moving parts, making it ideal for point-of-sale terminals, small machinery, and communication equipment.

Who is it for

This supply is built for system integrators, OEMs, and service technicians who require a dependable multi-output power unit in space-constrained environments. It suits applications such as industrial control boards, test instruments, and legacy computer peripherals that still rely on negative voltage rails.

Main features

• Triple output: +5V (8A), +12V (3A), -12V (0.5A) for mixed logic and analog circuits
• Wide input range 85–264VAC or 120–370VDC, usable worldwide without switches
• Open frame design with free air convection cooling – silent and maintenance-free
• Full protection: overload, overvoltage on CH1, and short circuit with auto-recovery
• Meets UL60950-1 and TUV EN60950-1 safety standards, EN55022 Class B EMC
• Compact footprint and low profile for easy integration into tight chassis

Tips

Mount the PT-65A with at least 10mm clearance around ventilation openings to ensure proper convection cooling. For applications with high inrush current, consider an external NTC thermistor. Always verify the total combined load does not exceed 65W, and derate output by 2.5% per degree above 50°C ambient.
