LDN Series Laser Diode Drivers
The New LDN series laser diode drivers are the second generation of precision CW/Pulsed diode drivers offered by Lumina Power. Building on more than a decade of experience in laser diode driver technology the new LDN family incorporates the features of the LDD and LDY models. New upgrades include increased energy storage for better pulsed performance, newly designed magnetics for cooler operation, lower inrush current at start-up and availability of an optional Performance Level “E” laser safety feature.
Offered in 4 power levels from 600 to 2000 watts the LDN family of laser diode drivers offer laser designers the most advanced and proven power supply technology available.

Description
1
Enable (input)
(note1)
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.
2
Crowbar Status
(Output)
High =Crowbar ON = 0
Low = Crowbar OFF =
+5V
The Crowbar Status reports the status of the shorting crowbar clamp
across the output. The crowbar will short the output when the output is not
ENABLED via Pin 1, or if the output is ENABLED via pin 1 but the control
circuitry has detected a no- load condition or a voltage requirement on the
output that exceeds the maximum voltage rating of the unit.
3
Interlock (Input)
Open = OFF
Connect to GND = RUN
The Interlock function can be connected to external interlock switches such
as door or overtemp switches.

Vout Monitor (output)
0-10V = 0-Voutmax
(note 2)
The output voltage monitor.
6
Iout Monitor (output)
0-10V = 0-Ioutmax
The output current 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) TTL High = On
TTL Low = Off
Default = On
The output may be pulsed by applying a TTL signal to Pulse Control, pin 8.
The amplitude of the output current pulse is determined by the current level
programmed via Pin 7, Iprogram(+). Rise/fall fall times of <1ms are typical.
Contact Lumina Power for faster rise and fall times.

Over Temp Warning
TTL High = High Temp
TTL Low = Temp Ok
When temperature of main heat sink exceeds 65 Deg C, Pin 11, the Over-
Temp Warning, will go to a TTL High to indicate unit is in danger of
shutting down due to over-temperature condition. When temperature
of main heat sink exceeds 75 Deg C, unit will shut down.

-15V (output)
Auxiliary 200mA

+15V (output)
Auxiliary 200mA
Note: Upon application of AC input voltage output current will be 0 regardless of Pin 1 setting. Enable (or toggle) pin 1 to output current. If maximum compliance voltage is less than 10V, Vout Monitor (pin5) 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. Applying a program voltage to pin 7 greater than 10.5 volts will latch power supply. Output current will not exceed 105% of rating
