myVolts AC 85-265V to DC 12V 8A 100W Power Supply

SKU CH-WH9D-TMPKV

Converts AC 85-265V to 12V DC at 8A with 100W continuous power and overload protection

  • Product typeAT
  • Wide 85-265 V input suits global mains
  • 12 V 8 A output delivers 100 W continuous
  • Built-in overload, overcurrent and short-circuit protection
  • Compact 115 x 65 mm board fits tight spaces
  • Low ripple under 200 mV for clean power

Compact AC-to-DC module for 12 V projects

This switching power supply board accepts AC 85-265 V at 50 or 60 Hz and delivers a regulated 12 V DC output. It is suited for hobbyists, integrators and repair technicians who need a small, self-contained unit to drive 12 V loads from mains voltage.

Open-frame board with 105.8×55.7 mm mounting pattern

The 115×65 mm PCB fits into custom enclosures or existing chassis using the stated hole centres. Built-in overcurrent, overload and short-circuit protection removes the need for external safety circuitry, freeing space and simplifying the surrounding wiring.

Continuous 100 W with 220 W peak capability

Under sustained load the unit supplies up to 8 A at 12 V with ripple below 200 mV. The higher peak rating handles brief inrush currents without shutdown, so the supply remains stable during motor starts or capacitor charging cycles.

Questions about this item

How much ripple can the 12 V output reach under full 8 A load?

The supply specifies noise ripple below 200 mV at the rated output.

Does the board need external airflow to sustain 100 W continuously?

No fan or heatsink is mentioned; the unit relies on its own enclosure for heat dissipation.

What mounting holes must the chassis provide for the 115 × 65 mm PCB?

The board uses fixing pores spaced 105.8 × 55.7 mm centre-to-centre.
