The Critical XR-D has a full colour display with large, easy to read fonts and you can change its colour theme to your liking. The XR is operated via a touch interface, making it easy to cover for hygiene purposes. The display shows several different settings: volts, amps, duty cycle and settle (similar to follow-through). It can also record your session time with an hourly rate. The XR-D can store up to 6 different voltage presets, making it easy to switch between machines or between lining and shading. Unlike previous Critical Power Supplies, the XR-D’s housing is made of aluminium. The Critical XR-D can be operated with or without a foot pedal thanks to the pedal override button. There is also an option for a jump start, which can be used for rotary machines that need an extra boost to get started. The XR-D comes complete with a magnetic mount.

The Critical XR-D has two machine inputs. If you need just one input, you can use the Critical XR which features a single input instead.
