myVolts S-100-12 12V 8.5A 100W Power Supply

SKU CH-JT30-JJDJD

A 100W 12V 8.5A switching power supply with short-circuit, overload and overvoltage protection, CCC, FCC and CE compliance, and an aluminium-alloy chassis for industrial, LED, CCTV and 3D-printer use

  • TypeAT
  • High efficiency and low DC ripple for stable power delivery
  • Operates reliably from 0 to 40 °C with long service life
  • High insulation strength ensures safe electrical isolation
  • circuit, overload and overvoltage protection safeguards connected equipment
  • 100 % full-load burn-in test validates 100 W continuous output

100 W Industrial Switching Supply

This 12 V 8.5 A switching power supply delivers 100 W of continuous DC power for industrial automation, LED displays, CCTV systems, 3D printers and similar projects. It accepts a universal AC 100-240 V input and provides adjustable voltage output through the ADJ terminal. The aluminium alloy enclosure aids heat dissipation without a fan. Protection circuits guard against short circuit, overload and overvoltage conditions.

Sustained Load Behaviour

The unit is rated for continuous operation at full 100 W load within a 0 to 40 °C ambient temperature range. A 100 % burn-in test at total load is performed before shipment to verify stable output under prolonged demand. Low DC ripple and high working efficiency are maintained during extended use. The supply carries CCC, FCC and CE safety compliance for regulated environments.

Adjustable 12 V Output Voltage

The +V/ADJ terminal allows fine adjustment of the 12 V DC output to match specific device requirements. This flexibility is the key specification when matching the supply to voltage-sensitive loads such as LED strips or radio equipment. Correct adjustment ensures the connected project receives the precise voltage it needs for reliable operation.

Questions about this item

How much heat does the 100W S-100-12 produce when running all day?

The aluminium-alloy case relies on natural convection, so it stays cool enough for 0-40 °C ambient without a fan.

What mains lead and DC wiring must I already have to install this unit?

You need a standard IEC-style cable for the L/N/ground AC terminals and two wires for the V+ and GND screw terminals.

Will the +V/ADJ trimmer let me match the 12V rail of my older 3D printer controller board?

Yes, the built-in adjuster lets you fine-tune the DC output around 12 V to suit legacy boards.
