General Description
Rack Enclosure Size:
1U, 400mm in Depth
The LDD / TEC 19" rack enclosure LTR-1200 is a
highly configurable, ready-made carrier system
facilitating the integration of up to 4 devices
belonging to either the LDD-Family of laser diode
drivers or the TEC-Family of Peltier/TEC
controllers. The system caters for power, cooling
and communication.
The combination of built-in devices (models,
number) is freely selectable by the customer, their
application will dictate the choice (12V or 24V) and
number of internal primary DC power supplies.
Meerstetter Engineering will take care of the
integration and provide a fully configured turnkey
solution.
Up to 4 fans drag air sidewise through the rack
enclosure. Their speed is managed by intelligent
fan control on a dedicated PCB such that air-
cooling becomes effective upon prolonged use at
high ratings.
For table-top operation, the rack mounting brackets
can be removed.
The current status of the rack enclosure and of the
built-in devices are indicated on the front side
display (2x40 characters) and by dual color LEDs.
The most important settings (parameters of the
built-in devices and of the front side data interfaces)
can be adjusted over the 5-way navigation switch.
For advanced operation and configuration, all
internal devices can be addressed over one of the
electrically isolated interfaces; therefore the
originally supplied TEC and/or LDD Service
Software’s can be used.
For continuous monitoring and control by
customers' systems, the serial communication
protocol 'MeCom' can be used: on one hand, it
allows direct control of the each built-in LDD and
TEC device, on the other hand it allows polling
further information about the overall system status.
For fast signals (such as LDD pulse triggering)
three digital (electrically isolated) input lines are
available. Also, one digital output is available (
e.g.
for error indication).
The integration of third party hardware (such as
fiber-coupled diode
lasers) is possible
if
dimensional requirements are met.
