SR-2304NP DALI 4-channel LED dimmer CV 12-36 V DC 5A DT6

Sunricher SR-2304NP is a professional four-channel DALI LED dimmer with a constant output voltage (CV), designed to regulate the intensity of LED strips and other LED lamps powered by a voltage of 12 to 36 V DC.

The device supports DALI-2 DT6 and allows joint or independent control of four output channels. Thanks to flexible addressing and the possibility of control with a classic button, it is suitable for residential, commercial and intelligent electrical installations.

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-2304NP allows setting 1 to 4 DALI addresses, so individual 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. The dimmer is therefore suitable for controlling several single-color LED circuits from one device.

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

The device allows 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-2304NP also supports the function Push DIM, which enables lighting to be switched on, off and dimmed using a normal button without the need for a DALI control unit.

The dimmer is equipped Push & Plug type plug-in terminals, which facilitate the connection of wires and simplify assembly.

The SR-2304NP can be integrated into a KNX system via a compatible KNX DALI gateway. It is also suitable for separate DALI lighting systems and applications in which control of several lighting circuits is required.

If higher power is required, the dimmer can be combined with a compatible power amplifier of the LED signal.
