Overview:

A four channel dimming RAK, designed to be wall mounted in an electrical cupboard. The
dimmer has 4 separate dimming channels that can control a total of 2400W/2000VA of
trailing edge dimmable lighting loads. In parallel with the 4th dimmer channel is a separate
switched relay channel for LEDs or Fans or other non-dimmable loads.

The RAK4-T is used for mains dimmable LEDs, tungsten and all other trailing edge
dimmable loads.

RAK4s, combined with a Link device (RxLINK or RAK-LINK) can either be used as a single 4

RAK4s can be also be used in combined stacks with RAK8-MB units on the same “Link”
device. Up to 8 RAK4s can be used per RAK-LINK and up to 4 RAK4s per RxLI
