DSA-0421S-24 1 39 A switched-mode power supply

A switched-mode power supply (SMPS) is a very commonly used type of power supply. Hakkuri poweri is usually quite light in relation to its efficiency. The chopper is perfectly suited for all kinds of situations where a little more power is needed, but the weight of the power source must be minimal. Chippers also pretty much invariably have a wide operating voltage range (typically 100...240VAC) and 50Hz or 60Hz electricity is also suitable for them. When choosing a power source, you need to know a few simple things (usually written on the device or its power source): Operating voltage (in Finland and Europe 230VAC) Output voltage (usually you have to be precise here, i.e. if the device says 12VDC, use a 12VDC power source, unless you know for sure that your device will work with other voltages as well) Does your device use alternating current (AC, VAC) or direct current (DC, VDC) The power or current requirement of the power source How much output current capacity must the power source have (If the device reads amperes (A), then the power source must have at least that much, i.e. an 8A power source is suitable for a 2A device as well as a 2A power source) How much power must be in the power supply (If the device says the amount of power (W, watt), then the power supply must have at least that much, i.e. a 100W power supply is also suitable for a 30W device as well as a 30W power supply) You can calculate the power (watts) by multiplying the output current (amps) x the output voltage (volts). You get the output current by dividing the output power (watts) by the output voltage (volts). Type of connector, if your application requires a connector (i.e. by measuring you can find out if it is compatible, unless you want to change the connector of the power supply)
