LED die/chip, 24V, 3W, CCT Adjustable 2700–6000K, CRI97

LED chip, 24V, 3W, CCT adjustable 2700-6000K, CRI97

Compact 24 VDC 3W LED chip with adjustable colour temperature (CCT) 2700-6000 K. The colour rendering index is of very high quality, CRI97. 200-300 lumens depending on the colour temperature of the light, less in warm, more in cold. This LED circuit is CCT adjustable, meaning that the colour temperature can be adjusted by mixing the warm and cool white light channels. The bracket is included in the price.

Control

The LED chip should be connected to a 24V CCT controller or a suitable 24V DC power supply that allows for per-channel current limitation. That is, the total power load on both channels must not exceed 3W.

The cooling recommendation is 70g, i.e. the size of the heat sink should be at least 40×15 mm (aluminium).

We offer 24V CCT controllers for RF, Zigbee and DALI systems.

Dimensions:

Chip: 13.5mm x 13.5mm

LED diode diameter: 7.5 mm

Bracket: 37mm x 29mm

Connections

Wiring instructions

2 pole CCT control:

Use the 2W+ and 2C+ terminals to connect to the corresponding terminals of the controller

3 pole CCT control (most common):

1. Connect W- to the warm negative pole (WW-) of the LED driver

2. Connect C- to the cold negative pole (CW-) of the LED controller

3. Connect C+ and W+ to the same positive pole of the LED controller (+)

4 pole CCT control (rarest):

1. Connect W- to the warm negative pole of the LED controller (WW-)

2. Connect C- to the cold negative pole (CW-) of the LED controller

3. Connect the W+ LED to the positive pole of the controller (WW+)

4. Connect C+ to the positive pole of the LED controller (CW+)

Note.

Do not connect directly to a 24 V power supply without a current limiter, because if you supply 3W to both channels at the same time, you will supply 6W to the circuit and it will break down.

Ensure good thermal conductivity; use either a heat sink or an equivalent heat sink as a heat sink. Use a thermal/acid paste.
