Power Repeater
EV4 4-Channel Power Repeater
Product Details
What it’s for: running longer or higher-wattage strip than the controller alone can power. A power repeater (also called an amplifier) sits between the controller and the extra strip. The controller still sends the dimming signal — the repeater drives the strip from its own power supply, so the controller’s output limit stops mattering. The controller powers the first stretch of strip directly; each repeater powers the next, in series or parallel, without limit.
When do you need one? Our 24V CCT strip draws 14.4W per metre. A 5-metre run is 72W — 3A at 24V, comfortably within the controller. Stretch that to 20 metres and it becomes 288W — 12A — more than the controller should carry, so you split the run and let a repeater carry the rest.
The EV4 is the RGBW-run repeater: four 5A channels that pair channel-for-channel with a WT5 driving RGBW strip — up to about 400W of RGBW strip (roughly 100W per channel) once you allow the 20% safety buffer. It equally suits RGB, dual-colour or four white circuits.
Which controller & repeater for which strip?
- White (single-colour) strip — WT1 controller + EV1-X repeater
- CCT (tunable white) strip — WT1 controller + EV2 repeater
- RGBW strip — WT5 controller + EV4 repeater
Key features
- Adds up to ~400W of RGBW strip (about 100W per channel) — sized with a 20% safety buffer
- 4 channels at 5A each (20A max) — constant voltage
- Made for RGBW runs — all four colour channels amplified together
- PWM signal input — follows the controller’s dimming exactly
- 3kV optoelectronic isolation between signal input and power stage
- Expand in series or parallel without limit — add a repeater per extra run
- Screw terminals — 0.5–2.0mm² cable
- Reverse polarity, over-heat and short-circuit protection
