- LTS-DPA
- DPA series current controller easy to operate, output high precision voltage, can provide high precision control to LED light. It can be controlled by button or RS232, realized 0-255 grade brightness adjustment. With trigger function, can control the light on/off by external signal, and it has power off saving function also. It is a stable performance, powerful light controller.
Features
1.Easy to operate, each channel can be controlled independently with high precision.
2.Digital display, button control, easy to understand.
3.Can communicate with PC by RS232.
4.With trigger, faster respond speed, high reliability.
5.Power off saving function.

Connection step:
Step 1: connected the light and controller (Reference to the picture on the right).
Step 2: if need the external trigger control, please connect the external trigger signal with the controller trigger interface.
Step 3: connect power (AC96-264V 47-63 Hz), press the red switch “-”, indicator light up, “o” uplifted, power on.
Step 4: If need to control the luminance by PC, please connect the PC with controller by RS232 data line in the power off status, then control by our demo program or the program you write yourself. Can set-up the each channel parameter manual when operated by serial port mode. That’s to say, the upper computer and controller all can set-up the parameter, no need mode swapping.

Output interface
Initial state is open mode
TS up, output state is open mode
Initial state is off mode
TS down, output state is off mode
Trigger port setup<LTS-DPA24200-1S>
This series controller is low level trigger controller. Total 1 group trigger ports, each has +/- mark. To input low level 5-24V to +/- port can achieve the trigger function.
Trigger introduction: when output initial state is open mode, input 5-24V to trigger port, light off; when output initial state is off mode, input 5-24V to trigger port, light on.
Wire connection method of the external trigger signal
Sequence chart
Normal on mode (MANU mode)：
When connect external trigger signal, trigger “+” input high level 5-24V “-” ground connection, light off.
Normal closed mode (REMO mode)：
When connect external trigger signal, trigger “+” input high level 5-24V “-” ground connection, light on.
Specification: T1 is trigger delay time, T1≦80us T3≦80us.
