Interface

PIN (color)	DESIGNATION	DESCRIPTION
1 (green)	Enable	Apply +5V DC on this pin to enable work of LDD. While 0V are applied to this pin or pin is unconnected module is disabled. Once Fault has occurred module is blocked till you eliminate fault cause, then disable module and enable it again.
2 (orange)	Fault *	If module is enabled and some trouble has occurred, module automatically stops operations and sets Fault status (Fault loop is “closed”). In case of normal operations Fault loop is “opened”. Maximal allowed current in Fault loop is 50mA.
3 (transparent)	Interlock	When Interlock loop is “opened” output is inhibited. You should “close” this loop to start operations (electrical resistance of “closed” loop should be below 100 Ohm level). Once Interlock has occurred module is blocked till you “close” Interlock loop, then disable module and enable it again.
4, 9, 15 (black)	Interface Return	Return of all interface circuits. This pin is connected to the GROUND stud.
5 (yellow)	V OUT monitor	The voltage at this pin is a monitor signal proportional to the measured value of voltage on load. 0V at PIN5 corresponds to 0V at load. Voltage at PIN5 corresponds either to voltage at load (V_MAX < 10V) or to one-half of this voltage (V_MAX > 10V).
6 (purple)	I OUT monitor	The voltage at this pin is a monitor signal proportional to the measured value of output current. 0V at PIN6 corresponds to 0A. 10V at PIN6 corresponds to I_MAX.
7 (blue)	I program	Voltage applied to this pin sets output current. 0-10V DC are linear with 0-I_MAX.
8 (white)	Pulse	Apply +5V DC on this pin to allow the output. While 0V are applied to this pin or pin is unconnected output is inhibited.
10-12	–	Not used
13, 14 (red)	+15V OUT	Auxiliary 15 VDC output. Maximal current – 100mA.

Fault

Module sets Fault state in the following cases:

· overheating (temperature of the module exceeds 70+/–2 °C level).

To remove Fault status module must be cooled below 65+/–1 °C temperature.

· overvoltage (voltage on the load exceeds 110% of V_MAX level).

Most popular causes of such fault are load type mismatch and load absence.

· overcurrent (output current exceeds 1.05 I_MAX level)

· incorrect I Program (input voltage exceeds 10.5V level)

Once Fault has occurred you should eliminate Fault cause, then “reboot” module (DISABLE module and ENABLE it again).

Diode Laser Driver (Laser Diode Driver, Diode Driver)

The laser diode driver LDD-AAVV-T is a high current-constant laser diode driver with a thermo-electric cooler controller. Current control, transient suppression, over-temperature protection, short circuit protection, and over current limit are provided. A temperature sensor is used to measure the temperature of the laser diode and then the constant-temperature is kept by automatically adjusting the current of the thermo-electric cooler.

LDD Series CW OEM Laser Diode Drivers

The LDD series is a new family of OEM laser diode drivers designed for the emerging high power laser diode industry. The LDD series is ideal for high power applications where economy is important and performance cannot be compromised.

Compact size is possible due to the low-loss Zero Voltage Switching inverter and incorporation of planar magnetics. The LDD is virtually wire free.

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.

The LDD family has been designed with the knowledge that a high power laser diode is an expensive device. Rise and fall times are strictly controlled to reduce high voltage transients which could damage the laser diode.

(Refer to Figure 2, LDD Interface Schematic)
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.
