myVolts LRS-350-12/24/48V 350W AT Power Supply

SKU CH-WTES-MN9AG

Compact AT switching supply delivers 350 W at 12 V or 24 V with overload, over-voltage and short-circuit protection

  • TypeAT
  • Delivers 350 W continuous output for demanding loads
  • Accepts 94-264 V AC input for worldwide use
  • Provides 12 V and 24 V rails with 14.6 A total current
  • Built-in overload, overvoltage and short-circuit protection safeguards hardware
  • Compact 215 x 115 x 30 mm form factor fits tight spaces

Thin 350W AT Power Supply

This compact AT power supply delivers 350W of continuous AC to DC conversion in a 215x115x30mm form factor. It provides selectable 12V or 24V output rails with a maximum current of 14.6A. The unit operates on a wide 94-264V input range at 50-60Hz frequency.

Replaces Bulky Linear Units

The switching topology with half-bridge transistor configuration reduces volume compared to traditional linear supplies while maintaining ±1.0% voltage accuracy. The upgrade is worth it when space is constrained and efficiency matters, as the PWM modulation achieves 100% work efficiency rating. Built-in overload, overvoltage and short circuit protections safeguard connected equipment.

Limited to 12V or 24V Fixed Outputs

The supply offers only two fixed voltage options with no 48V rail despite the model designation. Output ripple noise measures 150mVp-p which may affect sensitive analogue circuits. Voltage and load regulation rates of ±0.5% suit general electronics but fall short of precision laboratory requirements. Operating temperature spans -10°C to 60°C.

Questions about this item

What are the dimensions of the 215*115*30mm power supply for case fit?

The unit measures 215 mm long, 115 mm wide and 30 mm high, so check that your chassis has at least that much clear space.

How is the AT power supply connected, and what wiring mistake should be avoided?

Wire the AC input to a 94-264 V mains supply, then connect the 12 V or 24 V DC output; reversing the input and output terminals will damage the unit.

When should the 350 W power supply be replaced based on its operating limits?

Plan replacement if the unit regularly runs above 60 °C ambient or if output ripple exceeds 150 mVp-p under load.
