Switching-mode power supply (also known as switched-mode power supply, SMPS) is very commonly used type of power supply. SMPS is perfectly suited for various situations where even a bit more power is needed, but the power supply weight must be minimal. Switching-mode power supplies usually have without exception a wide operating voltage (typically 100...240VAC) and they accept 50Hz and 60Hz electricity.
 
When choosing a power supply you need to know a couple of things (They are usually written into device or it’s power supply):
  • Operating voltage (in Finland and Europe 230VAC)
  • Output voltage (with this you usually need to be precise, ie if it is written 12VDC in device then use 12VDC power supply, if you are not certain that your device will work with other voltages as well)
  • Does your device use alternating current (AC, VAC) or direct current (DC, VDC)
  • Power supply power or current requirement
    • How much output current capacity is required from power supply (If a certain ampere (A) rating is written in device then power supply must at least supply that amount, ie 8A power supply can be used with 2A device as well as 2A power supply)
    • How much output power capacity is required from power supply (If a certain watt (W) rating is written in device then power supply must at least supply that amount, ie 100W power supply can be used with 30W device as well as 30W power supply)
      • Power (watts) can be calculated by multiplying output current (amperes) with output voltage (volts). Output current can be calculated by dividing output power (watts) with output voltage (volts).
  • Connector type, if your application requires connector (ie measuring will tell you if it is compatible, if you do not want to change the power supply connector)
Installation method:
  • Into 35mm DIN rail
Switched-mode power supply advantages:
  • High efficiency
  • Low loss of power
  • Small size and weight
  • Small standby power consumption
Application examples:
  • LED lighting power supply
  • Power supply for industrial needs
  • Programmable logic units power supply
  • Point of sales appliances power supply
  • Power supply for your own do it yourself projects
