An Endurance laser box ver 1.0

Measure voltage and temperature

Control the power consumption

Adjust the laser power

Your laser driver with ultimate abilities:

• Adjustable DC/DC. Setup any voltage and current limits for your laser module.
• TTL control (PWM): 3.5V-24V
• Voltmeter + ammeter measuring voltage and current to the laser.
• Voltmeter measuring incoming voltage.
• A thermal sensor measuring temperature on the laser diode.
• Adjustable duty ratio 0-100%.
• Adjustable laser frequency: 1Hz-1000Hz.
• Operating PWM frequency: 250-500 Hz

About step-down (buck) converter features:

• Input: 7-32VDC 
• Output 1.5-28VDC
• Current: up to 8A (adjustable)
• Efficiency: up to 90%
• Operating temperature: 0-60С
• Voltage ripple: + -5%
• Conversion frequency: 180KHz

The laser box contains:

• 

  Voltmeter and ammeter

  Voltmeter and ammeter measure a real voltage and current consumption by the laser module.
  This gives a picture of the power intensity and laser power.

• 

   Temperature sensor

  The temperature sensor is added to the laser heat-sink and measures the temperature of the outside the laser heat-sink.
  The temperature outside the laser diode on a heat-sink should not be more than 55-60C (140F max)

• 

   Arduino board

  Arduino board is used to setup laser power remotely (duty ratio/frequency).
  Connect the Arduino board and change laser power parameters.

• 

   Endurance MO1 PCB

  Endurance MO1 PCB is needed to use the Arduino board.

• 

  Input voltmeter (optional)

  The input voltmeter measures the input voltage.
  Input current gives a picture is the power supply is enough for the laser. If the voltage drops then the power supply is not good enough.
