Description

Features

  • Best suited for OEM applications
  • Power factor correction
  • High reliability
  • ROHS compliant
  • Cost efficient

Laser diode drivers are designed for powering single diode as well as laser diode arrays. LDD series diode drivers has been designed as OEM product with easy integration. They have all protective features for reliable and safe long term operation. Embedded fan protects device from overheating and eliminate needs for additional cooling.

Control signals

Description of control signals of LDD series drivers

Connector type: 15 pin D-SUB female

 

PinPin Name and functionDescription
1Enable +5 to +15 V,
Low=OFF=0 V
The Enable function turns the output section of the power supply ON and OFF.
When the power supply is enabled, current is delivered to load as programmed via
Iprogram(+), Pin 7. Rise times resulting from Enable are approximately 100 msec
2Current OK outputDelivers low level on attempt to set current via Current program input higher as set
limit by internal trimmer. Useful if connected diode has maximal rated current which
is lower as maximal driver output current
3InterlockThe Interlock function can be connected to external interlock switches such as door
or overtemp switches
4GNDInterface return
5Voltage monitor 0-5 VMonitor output for direct measuring of diode voltage
6Current monitor
0-10V=0-Ioutmax
The output current of the supply can be monitored by Current monitor output
7Current program
0-10V=0-Ioutmax
The power supply output current is set by applying a 0-10 V analog signal to Current program input
8NC
9GNDInterface return
