Power Supplies
A simplified consideration of the electrical design of power supplies allows to consider them as a device with an input side and an output side. The input side and the output side are electrically isolated against each other.
Power supplies are categorized in various ways:
- Functional: Regulated, Unregulated, Adjustable and Isolated power supplies.
- Packaging: Bench, Open frame, Rack mount, Integral, External power supplies
- Power Conversion Method: Linear and Switching types.
There are two types of power supplies available, AC and DC power supply. Based on the electrical device’s electric specifications it may use AC power or DC power.
DC Types
- AC-DC Power Supply
- Switch-Mode Power Supply
- Linear Regulator
AC Type
- Single Phase
- Three Phase
Programmable Power Supplies
Uninterruptible Power Supply (UPS)
Switch Mode Power Supplies (SMPS) became particularly accepted in the field of industrial applications. Their ability to accept almost any input voltage, their high efficiency and their compact design make these power supplies a first class choice for the engineering of new or the extension of existing installations.
The safety of persons and installation equipment is a major aspect even for power supplies. The requirements to be fulfilled in order to guarantee this safety are specified by standardized regulations:
- Safety: Electrical isolation, Insulation, Grounding etc
- Approvals and Marks: UL, CE etc
- Standards: IEC/EN, CENELEC etc
