Key specifications

• Total power output: 50 W
• AC input voltage range: 85 to 264 V
• Maximum output current: 10 A
• DC output voltage: +3.3V
• Housing material: Metallic
• Design: Enclosed single output AC-DC power supply

How to use

Installation should be performed by qualified personnel in accordance with local electrical safety regulations. Mount the metallic housing securely to a flat surface or within a ventilated enclosure to ensure adequate thermal management. Connect the AC mains supply to the designated input terminals, ensuring the correct phase, neutral, and earth connections. Verify the output voltage terminals with a multimeter before connecting your load device to ensure proper polarity and voltage levels.

What to consider before purchase

• Verify that your total load requirements do not exceed the 50 W power limit and 10 A maximum current.
• Check the physical dimensions of the metallic housing to ensure compatibility with your mounting space.
• Ensure the operating environment meets standard indoor ventilation and temperature conditions.

Usage recommendations: Always disconnect the unit from the AC mains power source before performing any wiring modifications, maintenance, or inspections. Ensure sufficient clearance around the metallic housing to maintain optimal airflow and prevent thermal overload during extended operation.
