Power Supply Series

This is the power supply (supporting CW and pulse) for driving the laser diode (LD). The power supply for
driving a Peltier element and cooling unit all-in-one type required for driving LD is also part of our lineup.

LD Terminal Short Function
Function to short between anode and cathode of LD when power is switched OFF is equipped. By doing it,LD can be protected from static electricity, etc.

Goggle compatible white display
Letters can be displayed in white. Superior in legibility even when using laser-protect goggle.

Instantaneous power failure detection
LD can be safely protected by shutdown operation after instantaneous power failure detection, while there is electric current running after power has been cut off.

Various Alarm Functions
Alarm with screen display equipped enables prompt identification of cause and repair.

LD operation intergrator
LD operation intergrator function equipped, which is essential for LD lifecycle management.Zero reset available for LD replacement.

Full Interface
Interface equipped for setting in a system. Freely externally operable.

Simple Operation
Electric current limit setting and integrated time check can be done from a handle.

Electric current limit settings
Maximum electric current can be set in parameter. It prevents LD damage deriving from malfunction.

Laser Diode driver

Temperature of laser diode is kept at a certain point.
(Peltier, its drive circuit, heat sink, and fan equipped.)

Customized heat sink process can be done for laser diode

High capacity heat sink and fan adopted will cool down LD under high temperature.

Customer-supplied fiber couple laser diode is to be installed in this power supply.
