Choosing a Power Supply
When choosing a power supply, there are many things to consider. If you are manufacturing equipment that will be sold
to others, you probably want a supply with all the safety agency approvals. If size and weight are an issue use a switching
supply.
You must also decide what size of power supply (in terms of voltage and current) is needed for your application.
Voltage
The SWM24 is designed to give optimum performance between 24 and 70 volts DC. Choosing the voltage depends on
the performance needed and Drive+Motor heating that is acceptable and/or does not cause a drive over-temperature.
Higher voltages will give higher speed performance but will cause the Drive+Motor to operate at higher temperatures.
Using power supplies with voltage outputs that are near the drive maximum may reduce the operational duty-cycle sig-
nificantly. See the chart below to determine thermal performance at different power supply voltages
If you choose an unregulated power supply, make sure the no load voltage of the supply does not exceed the drive’s
maximum input voltage specification.
