Rako Dimmer Leading Edge Rack 4 Channel

Rako RAK4-L
4x5a channel dimming rack leading edge. Stackable 20a/box maximum load.

Rako RAK4-L Overview
- A four channel dimming rack, designed to be wall mounted in an electrical cupboard.
- Incorporating the latest dimming technology. Hybrid IGBT design enables leading and trailing edge control of lighting loads, quietly and smoothly.
- The dimmer has four separate dimming channels that can control a total of 4800w/4000va of leading edge dimmable lighting loads.
- For wireless systems, The RAK-4L requires a separate RF receiver (RX-LINK) which connects using standard CAT5 RJ45 sockets.
- For wired systems, the RAK-4 requires a separate connection unit, RAK-LINK.
- Controlled from any Rako RAKOM RF device, for example the RCP07W push button RF wall plate.

Central Control
- RAK-4L 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. All communication is carried out using the RAKOM RF, particularly useful for reducing installation and cabling costs.
- The RAK-4L units are designed to be centrally located in an electrical cupboard, utility room or garage.
- The RAK-4L leading edge dimmer can control up to 4800 watts of mains dimmable lighting loads.
- The hard fired Triac design provides control of a miltitude of lighting loads. Microprocessor control combines smooth reliable dimming with dynamic safety features such as auto-resetting over current, temperature shutdown and voltage surge protection.
- For wireless systems, the RAK-4L dimmer requires a seperate Rako RF receiver (RxLink), this unit connects using a single CAT5 RJ45 data bus. The RxLink receiver can be used to connect up to four RAK-4 dimmer units.
- The RAK-4L dimmer can be used seamlessley with other Rako modules, such as RDL in-line dimmers, RCP wallplates, RAH hand helds, MB1 timeclocks and forms the foundation of any Rako scene-set system.
- Each RAK-4L box needs to be fed by a 20A Type B MCB.
