SCA-SS-70-10
The servo-amplifier SCA-SS-70-10 is a powerful PWM-module for brushed DC motors with an output range
up to 700 Watt.
Six operation modes are integrated
•
Torque-control
•
IxR-control
•
DC-Tacho control
•
Speed-control by digital-encoder feedback
•
Voltage control
•
Analog positioning
The required operation mode is to be selected from the front side of the module by setting jumpers. This
SCA-SS-70-10 servo amplifier is protected against over current overheat and short-circuit of the output
stage against each other or to the power supply. By the usage of advanced technology and power- MOS-
FETs a high efficiency up to 95 %. An integrated choke in combination with the high PWM-frequency of 49
kHz enables the usage of motors with low inductance. In most cases no external choke is required
additionally. Due to the wide range of power supply voltage between 11 to 70 V DC the SCA-SS-70-10 can
be used very flexible with different kinds of power supplies within many applications. The robust aluminium
case has been constructed for different methods of mounting it, therefore a fast and easy integration is
provided. screw terminals and a durable controller-design allow a fast and straightforward commissioning.
