LEDs of indicating output status for each channel, LED on meaning the channel has output, or else no output
8
LED1~LED4, indicating output current of a channel increased by 350mA
9
Manual buttons, switch via short operation, relative dimming via long operation (no telegram)
10
KEY1~KEY4, switch current button for a channel, setting output current
11
Input terminals, input voltage 12~48V DC
Manually set the output current is described as follows:
Switching current button for a channel
: set output current for the channel, if the button (KEY1~KEY4) is
on, the output current of the channel is increased by 350mA and its LED (LED1~LED4) is on; if the button is off,
the current is not increased and the LED is off.
Switching current button for all channels
: set output current for all channels, if the button (KEY5) is on,
the output current of all channels is increased by 350mA and its LED(LED5) is on; if the button is off, the current
are not increased and the LED is off.
The button that set the output current is a dial switch, when it is toggled down, the button is on and the
corresponding LED is also on; when it is toggled up, the button is off and the corresponding LED is also off.
The corresponding output, dial switch and LED for each channel are as follows:
