Products Features

1. Programmable trigger mode available, 32 steps at max; the trigger source, intensity and trigger pulse width of each step can be set

2. Autosense of rated current for LED light

3. Trigger response time ≤ 15μs

4. Max trigger frequency up to 20KHz

5. Simultaneous communication of multiple channels available

6. Manual setting for max output current

7. 256 light intensity levels

8. Trigger signal input: connect an external signal source (e.g. a camera trigger signal) to strobe the LED light, and extend life span of light

9. Support RS232 communication

10. Support 100M Ethernet communication

11. Temperature controlled fan, longer life span

12. Withstanding high voltage (AC1500V 1min, leak current<10mA)

13. High insulation resistance (DC500V >20MΩ)

14. Easy to install: screw and DIN rail mounting available.

Device Overview

No.	Item	Description
1	4-digit display	1st number indicates the channel, other 3 numbers show the value
2	Trigger mode switch	To change the trigger mode
3	Serial port, female	RS232 communication interface with the PC
4	100 Mb Ethernet port	Ethernet communication interface with the PC
5	AC power input	To turn the controller on/off
6	Power switch	To turn the controller on/off
7	Intensity/ pulse width adjustment key	To adjust intensity or trigger pulse width. Press it, the chosen channel number twinkle on digit display; press it again will chose next channel. Rotate it in clockwise, the value increased; rotate it in anti-clockwise,the value decreased
8	Light connector	In total, four lights can be controlled individually
9	Trigger connector	In total, four lights can be controlled individually
10	Trigger connector	For connection with an external trigger source

Connection Setup

Step 1: Refer to drawing above on how to connect the light with the controller.

Step 2: For external triggering, connect the external trigger source with the trigger port.

Step 3: Connect the controller with 100 - 240V AC power source and switch the controller on. The digital display is lit.

If the intensity of the light shall be controlled via PC,

you need to connect the PC with an RS232 cable or Ethernet cable before the controller is switched on.

Use the provided software or your own application to communicate with the controller.

You can adjust the settings via the PC or manually.
