myVolts 12V-10A-9CH UPS PWM power supply box

SKU CH-TSSZ-0C2NM MPN 12V-10A-9CH

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

  • TypeAT
  • PWM regulation keeps voltage steady at 12 V
  • 240 W output delivers 10 A for multiple access devices
  • Delayed power-off prevents sudden shutdowns
  • Vertical mounting simplifies cabinet installation
  • Natural cooling runs silently without a fan

myVolts 12V 10A UPS PWM Power Supply

This PWM-regulated power supply box delivers a constant 12V output at up to 10A for access control systems. It operates from a 100-260V input with 85% working efficiency and includes a delayed power-off function. The unit uses natural cooling and a vertical mounting design for straightforward installation.

Sustained load behaviour with natural cooling

Under continuous operation the supply maintains 1% voltage accuracy and 1% load regulation while producing 45mpv ripple noise. Natural convection handles thermal dissipation without forced airflow, allowing the unit to run within a -20 to 80°C working temperature range. The full-bridge PWM topology supports stable 240W output across the 50-60Hz frequency band.

Replaces basic linear or unregulated units

The box upgrades installations that lack regulated voltage, delay-off sequencing or CE-certified safety for access control hardware. The jump is worthwhile when an existing supply cannot hold steady 12V under variable door-strike loads or when fan noise and dust ingress must be eliminated. Builders needing higher current or redundant inputs should look elsewhere.

Questions about this item

How much heat and noise does the 12V 10A PWM unit produce when running continuously?

It uses natural cooling with no fan, so it runs silently. The PWM design operates at 85 % efficiency, and the specified ripple noise is 45 mpv at full 240 W load.

What must I already have to install and power this 9-channel UPS supply?

You need an AC mains source of 100–260 V at 50–60 Hz, a vertical mounting surface, and the access-control devices that will draw up to 10 A total from the 12 V outputs.

Will the delay power-off function work with older 12 V access-control panels and locks?

Yes, the constant 12 V output with 1 % voltage accuracy and the delayed power-off feature are designed for standard access-control systems, so legacy panels and locks receive stable power during changeover.
