SR-2304B(WP) DALI 4-channel waterproof LED dimmer CV 12-36 V DC 5A DT6 IP67

Sunricher SR-2304B(WP) is a professional four-channel DALI LED dimmer with constant output voltage (CV) and a high degree of coverage IP67. It is designed to regulate the intensity of LED strips and other LED lamps powered by constant voltage, including applications in wet environments and outdoor installations.

The device supports DALI-2 DT6 and enables control of monochrome, Tunable White, RGB and RGBW LED lighting. Thanks to four output channels and flexible addressing, the individual channels can be controlled together or independently according to the requirements of the lighting system.

The dimmer works with the input voltage 12–36 V DC and provides four output channels with maximum current 5 A per channel. The total maximum output power reaches 240 W at 12 V DC, 480 W at 24 V DC or 720 W at 36 V DC. An external constant voltage power supply is required for operation.

Flexible DALI addressing

SR-2304B(WP) allows setting 1 to 4 DALI addresses, thanks to which the four output channels can be controlled together or separately.

When using one DALI address, all four channels are controlled synchronously. By setting four addresses, each channel can be regulated independently. This solution is suitable for controlling several separate lighting circuits as well as different configurations of LED lighting.

DALI addresses can be set manually using the integrated digital display and buttons or automatically via a compatible DALI control unit.

Dimmer provides continuous regulation of lighting intensity in the range of 0.1–100% with a logarithmic dimming characteristic that ensures a natural perception of brightness changes.

DALI and Push DIM control

In addition to control via the DALI bus, the SR-2304B(WP) also supports the function Push DIM, which enables lighting to be switched on, off and dimmed using a classic button without the need for a DALI control unit.

A short press of the button switches the lighting on or off, a long press changes the light intensity. The device also has a memory function that allows restoring the previous state after a power interruption.

Waterproof version IP67

Thanks degree of protection IP67 the dimmer is protected against the ingress of dust and the effects of temporary immersion in water. It is suitable for lighting installations exposed to moisture, for example outdoor architectural lighting, terraces or technical spaces.

The device is equipped with external connection cables that enable the connection of power supply, DALI communication and LED outputs.

The SR-2304B(WP) can be integrated into a KNX system via a compatible KNX DALI gateway. In combination with a suitable power source, it represents a practical solution for centrally controlled LED lighting even in more demanding conditions.
