Pin #

Pin Name

Functional Voltage Level

Description

1

Enable (input)

High=RUN=+5V to +15V Low = OFF = 0V

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 25msec.

3

Interlock (input)

Open = OFF Connect to GND = RUN

The Interlock function can be connected to exter-nal interlock switches such as door or overtemp switches.

4

GND

 

Interface return.

5

*Vout Monitor: (output)

0-10V = 0-Voutmax

The output voltage of the supply can be monitored by Vout Monitor. See note below

6

Iout Monitor (output)

0-10V = 0-Ioutmax

The output current of the supply can be monitored by Iout Monitor.

7

Iprogram(+): (input)

0-10V = 0-Ioutmax

The power supply output current is set by applying a 0-10V analog signal to Iprogram(+).

8

Pulse Control (input)

(LDD-3000 only)

TTL High = On

TTL Low = OFF

Default = On (LDD-3000 only)

The output of the LDD-3000 may be pulsed by applying a TTL signal to Pulse Control, pin 8. The amplitude of the output current pulse is deter-mined by the current level programmed via Pin 7, Iprogram(+). Rise fall times of <1msec are typical. Contact Lumina Power for faster rise and fall times. If left unconnected, the default will be ON for CW operation.

9

GND

 

Interface return.

+15V @0.25A (output)

 

Auxiliary +15V power supply for user. Up to 0.25A output current available. (not available on LDD-50)

15

GND

 

Interface return.

* If maximum compliance voltage is less than 10V, Vout Monitor will read output voltage directly. If maximum compliance voltage is greater than 10V, then Vout Monitor will be scaled such that 0-10V = 0-Voutmax.

　
OEM型准连续脉冲连续二极管激光电源
　

The LDQCW series is a new family of OEM diode laser pulsars designed for the emerging high power diode laser industry.

 

Lumina Power LDQCW diode drivers can be configured for compliance voltage requirements up to 100V.

Maximum efficiency is realized with circuitry that minimizes losses across the output pulsing circuit. Compact size is possible due to the low-loss Zero Voltage Switching inverter and incorporation of planar magnetics.

 

Leakage current is less than 250uA, power factor is greater than 0.99 and conducted emissions meet stringent European regulations. No additional line filter is required to meet EN 55011 emission requirements.
