What voltage input does it require?
It requires a 12V DC input via a 2.1mm barrel jack. A compatible power brick is included with most units.
How many modules can I power with it?
The number depends on the power draw of your modules. With a total of 25W (e.g., +12V @ 1.5A, -12V @ 1.0A, +5V @ 1.0A), it can typically power 6-10 average modules.
Does it have protection against shorts?
Yes, it includes overcurrent, short circuit, and reverse polarity protection to safeguard your modules.
How do I install the Row Power 25?
Install it like any Eurorack module: mount it in your case with M3 screws, connect the power cable to your modules, and plug in the 12V adapter.
Can I use it with a different power adapter?
Only use the supplied adapter or a regulated 12V DC adapter with at least 3A output. Using incorrect adapters may damage the module.
What do the LED indicators mean?
The LED shows power status. It is green when power is on and all rails are within spec. If it flickers or turns off, there may be a fault.
Is it safe to connect 5V modules?
Yes, the Row Power 25 provides a dedicated +5V rail for modules that require it. However, ensure the total current does not exceed 1A on the 5V rail.
Can I daisy-chain multiple Row Power 25 units?
No, they are not designed for daisy-chaining. For larger systems, use a single higher-wattage supply or multiple independent supplies.
How to clean the module?
Unplug the module and wipe the front panel with a dry, lint-free cloth. Avoid moisture and cleaning solvents.
