The 4ms Row Power 25 White is a clean, regulated, and protected power supply module for Eurorack systems.

It requires a barrel-style power brick (15V – 20V DC) and supplies power to modules via flying bus cables, direct connection, and/or bus boards.

The 4ms Row Power 25 White provides 25W of power for any eurorack modules (typically 4-10 modules*):
+12V @ 1.4A maximum, 1.0A recommended
-12V @ 0.8A maximum, 0.5A recommended
+5V @ 1.0A maximum, 0.8A recommended

*number of modules can vary depending on each module’s power consumption.

Simply plug a universal power supply (laptop style) into either of the barrel plugs on the 4HP panel. Connect your modules via flying-bus cables or the Bus Stick.

Multiple Row Power modules can be powered from a single power brick by daisy-chaining with an inexpensive barrel cable. The 4ms Row Power 25 White can also be daisy-chained to Pods. Each Row Power and Pod will be independently regulated and protected for ultra-low cross-talk between rows.

Features:
– Two power jacks for daisy-chaining multiple Row Powers and Pods: a common laptop-style power brick could power 3-5 rows (typical)
– On/off switch cuts power without interrupting the daisy-chain
– LED light indicates module is on
– Row Power 25 typically will provide enough power for 4-10 modules (this can vary, based on each module’s power consumption)
– Runs cool: Row Power 25 is efficient so it won’t heat up your system. Electronics like to chill!
– Skiff-friendly: only 25.6mm (1.01″) with power connector installed.
– Includes set of easily soldered holes for custom distribution systems (by soldering wires or MTA156 connectors)

Electrical and Mechanical Specifications:
– Module Size: 4 HP Eurorack format module
– Power Output:
+12V @ 1.4A maximum, 1.0A recommended
-12V @ 0.8A maximum, 0.5A recommended
+5V @ 1.0A maximum, 0.8A recommended
– Powered by laptop-style DC power supply: 2.1mm barrel, positive center, 15V-20V.

Maximum power output can be expected under normal operating conditions. Recommended power output is guaranteed under extreme temperature and limited airflow conditions.

Required (not included):
– 15V – 20V DC power brick or barrel jumper cable to daisy-chain from a powered Pod or Row Power
– Flying-bus cables, Bus Stick or other distribution system (for connecting Row Power 25 to multiple modules)
