Manual SCA-B4-70-10
SCA-B4-70-10(70V / 10A)
The servo-amplifier SCA-B4-70-10 is a powerful PWM-module for brushless DC motors with an output
range up to 700 Watt.
Three operation modes are integrated
•
Torque-control
•
Speed-control by digital-encoder feedback
•
Speed-control by hallsensors
The required operation mode is to be selected from the front side of the module by setting jumpers. This
SCA-B4-70-10 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 %. Due to the wide range of power supply voltage between 11 to 70 V DC
the SCA-B4-70-10 can be used very flexible with different kinds of power supplies within many applications
The robust aluminum case has been constructed for different methods of mounting it, therefor a fast
integration is. screw terminals and a durable controller-design allow a fast and straightforward
commissioning.
