1. DESCRIPTION
The CSA96 consists in a powerful and compact current switching amplifier designed to drive magnetic
actuators. It includes a power supply and as options, the possibility to connect an external power supply,
increasing output voltage and power capability, and a control board dedicated to advanced control of
actuators (position control, velocity control, etc.).
The external dimensions of the CSA96 are the following:
CSA96
Width : 140 mm
Length : 210 mm
Height : 59 mm
In case of optional controller, the height is 71mm.
The bottom plate is also a thermal interface used to dissipate the heat of the converter. The packaging also
features side openings for air circulation in order to enhance the heat dissipation.
2. MAIN FEATURES
The CSA96 is available in two versions, the first one features a powerful internal AC/DC converter which allows
to connect directly the amplifier on mains. The second permits to use a DC input voltage source.

4. ELECTRICAL SAFETY INFORMATION
The following safety symbols are used in this manual.
Warning
For you own safety and for your system security, be sure to carefully respect that
information.
Danger
This symbol alerts you about an electrical hazard.
Failure to follow these instructions will result in death or serious injury.
In order to achieve a safe operation of the CSA96 driver, some safety information must be given. This
information is intended to protect the user and the product, and allows safe operating of the product.
