WHAT IS IT?
4 Channel trailing-edge dimming rack. Ideal for mains dimmable lighting loads. Quiet dimming with electronic transformers and built-in short circuit protection. Stackable with other RAK4 units. Requires
RAK-LINK for wired or
RX-LINK for wireless systems.
A four channel dimming rack, designed to be wall mounted in an electrical cupboard.
Incorporating the latest dimming technology. Hybrid IGBT design enables
Trailing Edge control of lighting loads, quietly and smoothly.
The dimmer has four 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 dimmed loads.
The RAK-4T requires a separate controller/receiver which connects using standard CAT5 RJ45 sockets.
Controlled from any Rako Rakom RF or WIRED device, for example the RCM or WCM push button wall plates.
Central Control
- RAK-4T dimmer units can be used as simple 4 channel packs or joined to form multi-way stacks. 8, 12 and 16 channels stacks can be formed using the wireless receiver RX-LINK or up to 32 channel stacks using the wired system RAK-LINK.
- The RAK-4T units are designed to be centrally located in an electrical cupboard, utility room or garage.
- The RAK-4T Trailing Edge dimmer can control up to 2400 watts of mains dimmable lighting loads.
- The unique hybrid transistor design provides virtually silent operation, ideal for residential installations. Microprocessor control combines smooth reliable dimming with dynamic safety features such as autoresetting over current, temperature shutdown and voltage surge protection.
- The RAK-4T dimmer requires a separate Rako interface for control. Either the RF receiver (RxLink) or the WIRED controller (RAKLINK), these units communicate using a single CAT5 RJ45 patch lead.
- The RAK-4 dimmer can be used seamlessly with other Rako modules, such as RMT in-line dimmers, RCM/RCP wallplates, RAH hand helds, timeclocks and forms the foundation of any Rako scene-set system.
- Each RAK-4 box needs to be fed by a 10A Type B MCB.
