The power supply includes various protections that prevent damage to the LD.

External interlock:

External interlock function provides multiply protections at the same time:
Prevents inadvertent use;
Allows to connect an external emergency switch;
Allows to connect an external auto protect device (e.g. over-temperature switches).
The laser can only be turned on with shorted Interlock.

Other protections:

Soft-start: The soft-start function protects against unwanted overshoot of the LD in the power up process.
LD max current limiting: You cannot set the operating current above LD max current.
Over-temperature protection: The STM-MBHxxxx has automatic overheating protection. If the set external NTC max temperature is exceeded, the LD power supply will be automatically turned off. After the temperature returns to normal, the LD power supply can be switched on again.
State after switching on: After turning on the STM-MBHxxxx with the Standby button the LD power supply and TEC will always be turned off.
Memorization of parameters: In case of an interruption/unplanned shutdown, the STM-MBHxxxx remembers the settings that were set at the time of the last On/Off Laser command.

STO-LDD Series OEM Laser Diode Drivers

STO-LDD is a series of laser diode drivers intended for single laser diode driving as well as for laser diode arrays driving. Maximal output power ranges from 50W to 1500W, and maximal output current ranges from 5A to100A. These drivers may be used for industrial and medical applications.

Part number: STO-LDD-xx-AA

STO-LDD: STO-LDD series OEM diode drivers
xx : Maximum output power
AA: maximum output current

The maximum output voltage is maximum output power divided by output current. Current is adjustable in range 10-100% of Imax. Imax is selected by customer. Vmax is calculated as Vmax = Power / Imax. Voltage is adjusted automatically in dependence on load, but voltage cannot exceed Vmax.

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 (VMAX < 10V) or to one-half of this voltage (VMAX > 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 IMAX.
7 (blue)	I program	Voltage applied to this pin sets output current. 0-10V DC are linear with 0-IMAX.
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.
