1U PWR - Micro and powerful 1U format, 45W supply by Konstant Lab

1UPWR is a powerful, low noise, high-efficiency power supply solution for use with eurorack systems and portable eurorack cases that feature 1U rails.

Front panel contains a conveniently placed USB connector so you can charge external devices such as – your smartphone, tablet, lamp, or external sequencer. Under normal mode of operation when the power switch is ON, LED indications emit green light. LEDs go out when there is either a malfunction, overload, or short present so you always know when it is safe to work with your system. Front panel is made from high-quality CNC milled anodized aluminum. Many electronic parts are of SMD origin. 1U PWR is also made from quality PCB with copper thickness of 70um, which ensures high reliability of 1UPWR and minimal power losses on dedicated PCB routes. We recommend Meanwell GSM60A18-P1J DC Power Brick for one 1UPWR PSU and GST120A20-P1M* for two 1UPWR PSU solutions.

*If you need more power, you can use two 1U PWR modules, easily connect them together via our chain power cable and feed it with only one power brick (MW GST120A20-P1M).

Designed, manufactured, and assembled by hand at Konstant Lab - Slovakia.
