• Ripple & noise: <150mVp-p; line regulation ±0.5%, load regulation ±1%
• Connectors: IEC C14 input (cable not included), DC barrel jack output
• Operating temperature: 0°C to 40°C; storage -20°C to 85°C
• Certifications: CE, RoHS

Why choose it

This power supply is built for continuous duty. The stabilized output keeps voltage steady even when load fluctuates, protecting sensitive electronics. Fanless design means zero noise and no dust buildup, while the compact desktop housing fits neatly on a shelf or under a desk. Universal AC input lets you use it anywhere in the world with the appropriate plug adapter.

Ideal use cases

• Powering 12V LED strips or lighting systems in retail displays
• Running motors, pumps, or actuators in automation projects
• Bench testing automotive or marine electronics
• Supplying power to CCTV cameras or access control systems
• Charging 12V battery banks (with appropriate charge controller)

Good to know

The ATM 200-P120 ships with a DC output cable terminated in a barrel jack; if your device uses a different connector, you can easily splice or use an adapter. The AC input cable is not included, so pair it with a standard IEC C13 power cord. For best results, ensure adequate ventilation around the unit and avoid blocking the cooling vents.
