Power Supply Selection for Servo Amplifiers

White Paper reprint: by Rene Ymzon, Advanced Motion Controls


There are several factors to consider when selecting a power supply for servo amplifiers.

1. Power requirements

2. Isolation

3. Regeneration

4. Voltage ripple

Power requirements refers to how much voltage and current will be required by the amplifier(s) in the system.  Isolation refers to whether the power supply needs an isolation transformer.  Regeneration is the energy the power supply needs to absorb during deceleration.  Voltage ripple is the voltage fluctuation inherent in unregulated supplies.

Each consideration is discussed in detail in the following pages [click on the link below…]
