Rectangular metal enclosure, vertical mount, natural cooling, 9 output channels, 12V 10A PWM power supply

myVolts

myVolts 12V-10A-9CH PWM access control power supply delayed off natural cooling

SKU CH-4FRZ-XXDXM MPN 12V-10A-9CH

A 12 V, 10 A PWM power supply with nine channels, delayed power-off and natural cooling for access-control systems

  • TypeAT
  • PWM regulation delivers stable 12 V output for reliable access control
  • Delayed power-off function maintains voltage briefly during mains loss
  • 10 A continuous current supports up to 240 W load capacity
  • Natural cooling eliminates fan noise and reduces mechanical wear
  • Vertical mounting design allows quick installation in standard enclosures

Access Control Power Supply

The myVolts 12V-10A-9CH is a PWM regulated power supply box designed for access control systems. It delivers a constant 12 V output at 10 A with a delayed power-off function. The unit operates from a 100-260 V input and carries CE certification. It is built for vertical mounting in security installations.

Vertical Mount Natural Cooling

Vertical installation allows the supply to fit into standard enclosures without forced airflow. Natural cooling eliminates fan noise and reduces mechanical wear on connected access control hardware. The 85 % working efficiency limits heat rise inside the cabinet. A full-bridge topology supports stable operation across the 50-60 Hz mains range.

Sustained Load Behaviour

Under continuous load the supply maintains output voltage accuracy within 1 % and load regulation within 1 %. Output ripple noise stays at 45 mpv during extended operation. The working temperature range of -20 to 80 °C supports long duty cycles in varied environments. Delayed power-off ensures orderly shutdown of controllers when mains power is removed.

Questions about this item

What is the maximum continuous output current the 12V-10A-9CH can deliver before the 10 A limit is reached?

The unit provides a regulated 12 V output rated at 10 A continuous, giving up to 240 W of power for access control loads.

How much audible noise and heat does the natural-cooling design produce during 24-hour operation?

With no fan installed, the supply runs silently; heat is dissipated passively through the metal enclosure while efficiency stays at 85 % across the 50-60 Hz input range.

Which input voltage range must the site already provide for this PWM supply to start up?

The supply accepts 100-260 V AC at 50-60 Hz, so a standard mains circuit within that window is all that is required.
