LDDY Series Diode Drivers with TEC Controllers

LDDY series diode laser drivers with TEC controllers are designed to drive diode lasers. They can drive maximum 2 diodes and 4 TE coolers. Of them 2 TE coolers are used to cool diode lasers and 2 TE coolers are used to cool SHG crystal and THG crystal. The drivers are made in modules and thus the customer can select the modules (outputs of the drivers) according to his needs with lower cost and smaller size.

Our diode drivers are contact and reliable. They are ideal power supplies to drive diode lasers, fiber lasers and DPSS lasers.

LDD2 Series OEM Laser Diode Drivers

diode driverLDD2 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:     LDD2-xx-AA

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.

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.

Not used

13, 14 (red)

+15V OUT

Auxiliary 15 VDC output. Maximal current – 100mA.
