myVolts 12V 100A 1200W Switching Power Supply

SKU CH-WH70-FYPES

A 12 V DC power supply delivering up to 100 A from an 85–135 V AC input with overload, over-voltage and short-circuit protection

  • TypeAT
  • Delivers stable 12 V DC at up to 100 A for demanding loads
  • Wide 96–135 V AC input tolerates voltage fluctuations in industrial settings
  • Over-voltage, overload, over-temperature and short-circuit protection with auto-reset keeps equipment safe
  • Sealed aluminium housing with epoxy potting provides waterproof, dust-proof and shock-resistant operation
  • High-efficiency design above 80 % reduces heat and energy waste

12V 100A industrial power supply

This 1200W switching unit converts 110V AC input to a stable 12V DC output rated for up to 100A. It is built for industrial automation, LED displays, CCTV systems, 3D printers and similar fixed-installation projects that need high-current 12V power.

85-135V AC input with 80% load rule

The supply accepts a wide 85V to 135V AC range at 50-60Hz and delivers regulated DC12V with ±5% tolerance. Efficiency exceeds 80%, but the load must not exceed 80% of the 1200W rating. Protection covers over-voltage, under-voltage, overload, over-temperature and short circuit with auto-reset behaviour.

Not for motors, batteries or vehicle use

The supplier explicitly states this unit cannot drive motors or starting loads that exceed the rated current, and it is unsuitable for car power, battery charging, heating elements or laboratory electrolysis. Buyers needing those applications must select a different power source.

Questions about this item

Which power rating should I pick for a 12 V project?

This unit delivers up to 100 A at 12 V for a maximum of 1200 W, though the load should stay below 80 % of that rating.

What does the 1200 W figure mean once the supply is installed?

It is the peak output the supply can reach; continuous draw should not exceed 80 % of 1200 W to keep operation stable.

What input voltage range does the AC side accept and what limits it?

The supply accepts 85 V to 135 V AC at 50 Hz to 60 Hz, centred on a 110 V nominal input.
