MEAN WELL PT-45C 45W kolmislähtöinen AC/DC-hakkurivirtalähde

Industrial automation engineers often need a compact, reliable power source for control systems, sensors, and small motors. The MEAN WELL PT-45C delivers 45W across three isolated outputs (+5V, +12V, -12V), making it ideal for powering mixed-voltage electronics in factory floors, test benches, and embedded applications. Its open-frame design and free-air convection cooling allow easy integration into tight enclosures without forced airflow.

Key specifications

• Total rated power: 45W
• Outputs: +5V/4A, +12V/1.5A, -12V/0.5A
• Wide input range: 85–264VAC (120–370VDC)
• Efficiency: 74% typical
• Protections: overload, over voltage, short circuit
• Operating temperature: -10°C to +60°C
• Safety standards: UL60950-1, TUV EN60950-1
• MTBF: 200,000 hours minimum

Why choose it

The PT-45C offers a proven triple-output topology that simplifies system design by eliminating multiple single-output supplies. Its universal AC input and full international safety certifications make it suitable for global deployments. The open-frame construction keeps weight and cost low while allowing custom mounting in OEM equipment.

Ideal use cases

• Industrial controllers and PLCs requiring mixed logic voltages
• Telecom and datacom equipment with analog/digital sections
• Test and measurement instruments
• Embedded systems and robotics

Good to know

This power supply is designed for free-air convection cooling—ensure adequate clearance around the unit. It meets EN60950-1 for IT and industrial equipment. For applications needing higher peak currents, consider the PT-65 series.
