A supply voltage is required by every industry control circuit. However, because the industry control circuit is only a small part of a larger electrical environment, many specification parameters must be considered when selecting the appropriate supply device.
The designer’s constant questions during the design of a DC/DC converter are:
- What is the voltage range for the input?
- What is the voltage range of the output?
- What amount of power do I require?
The overview that follows provides a brief summary of the key facts that explain the story behind key parameters.
What kind of isolated power module do we need?
Bottling plants, rolling mills, conveyor belts, and printing presses are examples of typical industrial applications such as:
- Bus Isolation/Interface – RS232, RS485, CAN, Interbus, Profibus
- Digital circuit isolation
- Obtaining an isolated amplifier and an analog-to-digital converter
- Data collection and measurement
The input supply voltage is isolated from the …
