Connects to the laser tube's anode or positive end, providing high-
voltage current to power the laser.
Allows simple installation and removal.
Provides the real-time current value to the laser tube in milliamps.
Illuminates when current is being sent to the laser tube.
Holds the power supply's connection to the engraver's grounding
(FG) and to the main power supply (AC).
Tests fire the laser when troubleshooting problems. If the laser fires
successfully, the problem will usually be with the control panel or its
connections.
This terminal block ensures that the water sensor, interlocks, and so
on.
H: Connection for active-high devices
L: Connection for active-low devices
P: Line to the laser trigger, water, and other systems (such as a
door switch)
G: Ground wire for the control system, PWM level shifters,
potentiometers, etc.
IN: Input power for PWM level shifters or potentiometers
5V: 5V connection for digital signals
Illuminates the water cooling system is operating when connected.
Illuminates when the laser tube is in operation.
Allows you to connect the laser power supply to an external ammeter
while troubleshooting electrical issues. Its indicator lights show its
