DALI + Push + Phase Cut + 0/1-10V LED Dimmer

The Sunricher SR-2303P (4-in-1) is a versatile, professional-grade constant-voltage dimming controller designed for LED systems requiring diverse control options in one unit.

It supports four different dimming interfaces — DALI, Push-Switch, Phase-Cut (leading/trailing edge), and 0/1-10 V — selectable via an on-board DIP switch. 

With a wide input range of 12-48 V DC, this device supports a single output channel rated up to 20 A, delivering power from ≈240 W at 12 V up to about 960 W at 48 V, depending on load. 

When configured for DALI mode, it complies with standards IEC 62386-101, -102 and -207 and integrates seamlessly into DALI lighting networks. 

This controller is ideal for installations that may need flexibility — retrofits, smart lighting systems, or spaces where different control protocols might be used.

Its single-channel design keeps wiring simpler while providing heft in power and interface versatility.
Whether you’re specifying for signage, architectural LED strips, or adaptable lighting zones, the SR-2303P (4-in-1) offers reliable performance, broad compatibility and all-in-one flexibility.
