myVolts HiFi Amplifier SMPS LLC 500W AC110V Dual ±36V Power Supply

SKU CH-01T5-XM7S8

A 500 W switch-mode supply with LLC soft-switching that delivers dual ±36 V and auxiliary ±15 V rails for high-fidelity amplifiers

  • TypeAT
  • 500 W output drives demanding amplifiers
  • Dual ±36 V rails plus ±15 V auxiliary supply
  • LLC soft-switching topology for low internal resistance
  • Passive cooling handles up to 100 W without forced airflow
  • Compact 113 × 67 × 56 mm board weighs 350 g

High-Power Audio SMPS

This myVolts switch-mode supply delivers 500 W of continuous power from a 110 V AC source. It provides a dual ±36 V main rail plus a ±15 V auxiliary rail rated at 300 mA, making it suitable for high-performance amplifier builds.

Compact Encapsulated Build

The unit measures 113 mm by 67 mm by 56 mm and weighs 350 g, using epoxy encapsulation for the high-voltage circuitry. Natural convection cools the module at loads around 100 W, while forced airflow is required to reach the full rated output safely.

LLC Resonant Topology Limits

LLC soft-switching gives high conversion efficiency and low output impedance for strong dynamic response. The auxiliary rail is limited to 300 mA, so designs needing higher standby current must budget accordingly. Bare-board high-voltage areas demand careful insulation in the final chassis.

Questions about this item

Does the AC110V input limit the 500W output in any way?

The unit accepts AC110V mains and is rated for 500W continuous output at that voltage.

Will the 113mm by 67mm footprint with 56mm height fit my chassis?

The bare board measures 113mm long, 67mm wide and 56mm tall; allow clearance for the high-voltage areas.

How do I wire the dual ±36V and ±15V rails, and what mistake should I avoid?

Connect the main ±36V rails to the amplifier and the auxiliary ±15V rails to the preamp; never power the board without a load on the main outputs.
