�3 in 1� Laser Power Supply
(diode driver + Q-switch driver + DC power supply of
marking head)
|
|
In a diode
pumped Nd:YAG laser marker, a diode driver, a Q-switch driver and a DC
power supply are needed. They are individual 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.
Features:
-
Compact
in size and light in weight.
-
Modular
design for convenient maintenance.
-
Excellent performance.
-
Portable for easy moving.

The laser diode driver
LDD 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.

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. |

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. |
|

I program |
Voltage applied to this pin sets output current.
0-10V DC are linear with 0-IMAX. |

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 VMAX
level).
Most popular causes of such fault are load type mismatch and load
absence.
� overcurrent
(output current exceeds 1.05 IMAX
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). |

Notes:
1. Diode driver: Maximal output current (IMAX) is selected
by the customer in range 10-100A. Module�s output current can never
exceed this IMAX value.
2. Diode driver: Compliance voltage (VMAX) is selected by the
customer in range 2-150V. Module�s output voltage can never exceed VMAX
value.
3. Diode driver: Maximal output power of the module (WMAX) is
defined as a product of IMAX and VMAX and can
never exceed 1500W
4. TEC driver limitations: IMAX(TEC) < 10A, VMAX(TEC)
< 20V, WMAX(TEC) < 150W
5. TEC driver: Standardly our TEC controllers are designed to get
feedback from 10kOhm NTC thermistors.
