30 Amp Switching DC Power Supply

The Sound PSV-300 Pyramid is a heavy duty switching DC power supply rated at 30 amps. It converts AC mains voltage into stable DC power for bench testing and powering car electronics away from the vehicle. The unit is designed as an installation tool for automotive workshops and hobbyists.

Replaces a vehicle battery for bench work

This supply replaces the need to run a car battery indoors when configuring amplifiers, head units or lighting systems. The 30 amp capacity covers most single component tests and typical installer workloads. Buyers who need continuous loads above 30 amps or multiple high draw devices simultaneously should look for a higher rated unit.

The unit is a benchtop design with rubber feet; no rack ears or wall brackets are included, so it sits on any flat surface without extra hardware.
