An Endurance FAP 800 Coherent laser control box

Description

Endurance offers a laser box for running FAP800 Coherent laser diode module

Getting started with a laser control box

Inside the laser box

• An AC/DC 2V 30A power supply (PSU).
• A driver controlling the laser with PWM signal (3.3-12V).
• our own TEC controller system that allows keeping the temperature around 15C.
• A dynamic PWM module that allows changing laser power with a potentiometer.
• Voltmeter + ammeter that allows checking the laser power.

Wiring and schematic

On the control and indication elements on the cover from the FAP and how to call it all:
1 – General food. I guess “Power (ON / OFF)”
2 – Laser power supply and Peltier. I think something like “Laser & TEC Power (ON / OFF)”
3 – Volts/amperes on the laser. I guess “Laser Input”
4 – Volts/amperes per Peltier. I guess “TEC Input”
5 – Thermal relay
Current temperature. I guess “Current Temperature”
Set temperature. I guess “Set Temperature”
6 – Working with PWM
Mode “0” – work from PWM directly from the machine
Mode “1” – work from PWM through the regulator.

7 – Regulator block. I don’t know if it is necessary to separate it and somehow sign it separately.
8 – Regulator modes.
Mode “0” – The regulator is off. Here it is clear “OFF”.
Mode “1” – The laser is always on. The power is set by the regulator.
Mode “2” – Through the PWM wires from the machine, on which there is no PWM, a voltage of 3.5-24V is supplied, through which the laser is turned on. The power is set by the regulator.
9 – The handle of the regulator. I don’t know if I need to sign it.
10 – Power indicator.
11 – LED that turns on when voltage is supplied from the machine through the PWM wires. Works only in mode “2”
