1. LDD Series Laser Diode Drivers

The laser diode driver LDD-AAVV is a high current-constant laser diode driver without TEC control. Current control, transient suppression, short circuit protection, and over current limit are provided. A digital meter shows the output current and output voltage.

Features:

Specifications:

xx- remarks

Output current 0-30A adjustable
Output voltage Max. 24V automatically adjustable
Ripple <80mV
Alarm and protection Over load, over temperature, over current and no load
External current adjusting 0 -10V corresponding 0 – max. current
Input voltage 220VAC, 50Hz/60Hz, +/-15%
Dimension 482×88x260mm
Net weight 6.5kg

Remark:

To select a driver, you may finalise the output voltage first and then finalise maximum output power. The maximum output current will be the maximum power pided by the output voltage.

2. LDD Series 3in1 Lser Diode Drivers

In a diode pumped Nd:YAG laser marker, a diode driver, a Q-switch driver and a DC power supply are needed. They are inpidual with large size and then the size of the laser marker is also large. It is not convenient to move the laser marker due to large size. We have developed a “3 in 1” laser power supply and the above power supplies are integrated into one unit with compact size.

Specifications:

Model:   LDD-AAVV-RFxx-3in1

LDD-laser diode driver

AA-maximum output current (A). The output current is continuously adjustable.

VV-maximum output voltage (V). The output voltage is determined by current  & diode’s resistance.

RFxx-RF output power, xx is 50W or 75W.

If “3 in 1” laser power is used in a laser marker, the marker will be simple and it consists a laser head with a marking head and a power supply as shown as follows. The marker will be portable.

“2 in 1” laser power is also available. It includes a diode driver and a Q-switch driver (RF driver).
