SSA Servo Amplifier


The SSA is a miniature PWM servo amplifier for brush type Motors in the range of up to 850 Watts. The amplifier utilises power MOSFET and SMT components resulting in a high power/volume density. It is an OEM oriented product for automated machines and instrumentation.

The amplifier is a panel mount version and it is so designed that two amplifiers can be mounted on a standard Eurocard.
