The Eurorack Switched-Mode Power Supply 1000, or “Euro SMPS 1000” is a high-quality, efficient, and affordable power supply for your Eurorack system.

Features
- Powerful: Delivers 1 Amp on the +12V rail.
- Compact: Occupies only 4HP with a depth of 50mm (add a few mm for wiring clearance).
- Lightweight: No heavy transformer. Perfect for small skiffs and travel cases.
- Cool operation: generates almost no heat.

High-Quality design
The module uses three efficient MeanWell DC-DC switched-mode converters, ensuring low noise and high power without significant heat dissipation. It supports a wide input voltage range from 16V to 20V. Any standard laptop-style power supply (16-20V, 2A) with a 5.5mm/2.1mm DC jack connector, center-positive DC jack will work.
Protection & Safety
The input is protected against reverse polarity and voltage surges. A resettable fuse safeguards against overloads; the PSU will automatically resume operation once the fault is corrected.
Noise filtering
Each output rail has a dedicated low-pass filter to eliminate residual switching noise.
Specifications
- Input: +16 to +20VDC at 2A
- Output:
- +12V @ 1A
- -12V @ 300mA
- +5V @ 1A
Connections
- Input: 5.5mm/2.1mm center-positive barrel connector.
- Outputs: provided on two screw terminal blocks for easy connection to bus boardsplus one 16-pin Eurorack connector (recommended for low-power, single-module use).
How to use
- Install the module in any 3U row.
- Power it using a generic 16-20V, 2A DC power brick (laptop style).
- Connect the output rails (+12V, +5V, 0V/GND, -12V) from the screw terminals to your bus boards.
