685 SERIES FEATURES

The ComboPak laser diode controller is an Arroyo OEM power supply that offers the same, solid quality instrumentation our bench top units are known for, in a smaller, cost-effective solution for custom systems.

The ComboPak brings the great performance and protection features found on the ComboSource into a package that is 1/3 the original size. In addition to a USB port, the ComboPak replaces the standard user interface with an digital control interface not found on the comboSource, allowing operation of the controller without the need for a computer.

The ComboPak has all the features you expect in a laser driver and temperature controller, such as safety interlock, ESD protection, hardware limit circuits for current and voltage, and temperature limits.

OVERLAPPING LASER PROTECTION

Including safety interlock, ESD protection, hardware limits for current & voltage, and soft power-on.

MULTIPLE OPERATING MODES

Choose from:

  • Constant Current
  • Constant Power
  • Constant Voltage

REMOTE VOLTAGE SENSING

Supports an extra pair of sensing wires to measure the operating voltage of your laser diode or LED.

ROBUST ANALOG INTERFACE

Provides on/off control, and status monitoring signals as wellas analog modulation input.

AUTO-TUNE AND MANUAL PID SELECTION

One button auto-tunes your control loop, or choose from 8 factory gain settings, or select your own.

PRECISION TEMPERATURE CONTROLLER

Over 10 Watts of TEC control and up to ± 0.004 ºC. Supports industry-standard thermistor-type sensor input.
