LA75 OEM
Objective
The LA75 OEM is the OEM and standalone version of the standard product LA75 version. This version
can drive and control a piezoelectric actuator in open or closed loop with controllers from CEDRAT
TECHNOLOGIES from DC input voltage. It can be used separately or can be coupled with other axis
in a cabinet to drive multi-axis piezoelectric mechanisms. The principal objective of this product is
to address the industrial applications to be integrated in standard cabinet with DC stabilized input
voltage.
Description
The performances are based on a 400W output power in a smaller package able to be integrated with
a back plane to be assembled in industrial cabinet. The driver is supplied with standard DC/DC power
supplies based on 48V versions.
The thermal management can used an additional heatsink (with fan if necessary) mounted on the
side of the product.
The LA75 OEM is composed of a main printed circuit board and an mechanical interface to mount
additional heatsink (when required). A rear connector includes the main electrical connections to
connect the input voltage, the consign, state of the driver and the controller (if option is chosen). An
additional front connector with standard Lemo connector connects the piezoelectric actuator.
In applications which require high power, an additional heatsink can be mounted on the received
panel (option Heatsink) to improve the thermal performance of the product.
