DFS4000 Lighting System
Manufactured in the UK, DFS4000 forms a compact easy to wire LED node with single colour, RGB or RGBW options. The system is principally for fixed installations.
Each unit comprises an aluminium base which attaches to the mounting surface. A flat two conductor cable either runs along or is fed from behind the mounting surface. The DFS4000 LED PCB assembly presses onto the aluminium back and connects to the cable with insulation displacement pins. The system has an optional diffuser which fits over the complete assembly.
DFS4000 LED nodes are powered from VP or IP series drivers and are wired with a simple two conductor cable. Each LED node is individually controllable.
All Glasson Electronics LED products employ linear current control as opposed to PWM. This provides extremely smooth dimming even at low intensities.
DFS4000 Typical Installation
Main Features of the DFS4000 Lighting System
- Polarity insensitive – connects to the cable either way around.
- Linear current control (not PWM) for excellent flicker free colours when viewed with a video camera.
- Excellent step free smooth dimming.
- Each node has a unique address which is user programmed using the hand programmer. The address can be reprogrammed thousands of times.
- Internal fuse resistor to prevent a single Node failure compromising the whole system.
- Dimensions – 40mm diameter
- Height without diffuser – 11.5mm
- Height with diffuser – 19mm
- Weight 20g.
- Drive voltage – Hi 24-36V, SH 40-48V.
- Current 55mA.
- Wattage Hi = 1.76W Super High = 2.0W
DFS4000 Operation
A system is comprised of a VP or IP series mains driver. These accept universal mains supply and output a DC voltage with the combined power and data signal modulated on the supply. Up to a full DMX universe (200 single colour, 170 RGB or 127 RGBW) DFS4000 nodes all wire in parallel from the driver output. Nodes can be wired in strings or individually wired and connect back to the power unit outputs using terminals or splitters. Once wiring is complete, each lamp is assigned a number using the Infra Red Hand Programmer. The number makes a given lamp unique on the system. Note that multiple nodes can be assigned the same number and will then operate from the same DMX Channels. Once installation is complete each node will respond to the assigned DMX channels.
