myVolts 12V-10A-9CH power supply Emoshayoga controller delayed off PWM natural cooling

SKU CH-5DMS-5R0ZP MPN 12V-10A-9CH

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

  • TypeAT
  • Constant 12V output backed by PWM regulation
  • Delayed power-off keeps access control running after mains loss
  • 10A capacity delivers 240W for multi-door systems
  • Natural cooling removes fan noise and dust ingress
  • Vertical mounting simplifies cabinet installation and servicing

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 uses full bridge topology and operates from a 100-260 V input. Vertical mounting makes installation and removal straightforward.

Natural cooling thermal profile

Natural cooling eliminates fan noise while maintaining an 85 percent working efficiency across the 50-60 Hz operating range. The supply tolerates ambient temperatures from -20 to 80 degrees without active airflow. Output ripple noise is specified at 45 mpv with voltage and load regulation each held to 1 percent. CE certification confirms compliance for the intended access control scope.

Build integration requirements

The vertical form factor suits cabinet or wall mounting where horizontal space is limited. A 240 W output capacity supports multiple access devices from a single unit. Delayed power off preserves lock state during brief mains interruptions. Buyers needing higher current, redundant inputs or rack mount brackets will need a different solution.

Questions about this item

How is the 12V-10A-9CH unit mounted and what step is often missed?

Mount the box vertically using the supplied accessories; the step often missed is securing all mounting points so the natural-cooling airflow path stays clear.

What maintenance will the 12V-10A-9CH need over time?

Periodically vacuum dust from the ventilation slots to keep the natural-cooling path effective; the internal UPS battery will eventually require replacement.

What limit appears first when the 12V-10A-9CH runs continuously at full load?

The 240 W output power ceiling is reached first; sustained 10 A at 12 V will hit this limit before the 80 °C operating temperature boundary.
