ref#2

We have developed a 24V output AC/DC isolated power supply reference board specifically for industrial equipment.

When designing a system for a drive system such as a motor, you probably use a large-capacity AC/DC isolated power supply to supply power to the motor system circuit and control board. The reference board developed this time is designed so that even if a trouble occurs in the motor-related circuit by supplying this control board with a separate AC/DC power supply, the control board running with a separate power supply will not be affected. Developed for system construction.

This reference board is designed using Analog Devices' isolated power supply controller IC (type: LT8315) and a general-purpose transformer (Wurth Elektronik's part number: 7508110419). Insulated power supplies often have problems with the availability of transformers, but since they are general-purpose products, they can be safely applied to systems for industrial equipment.
