Article Source：Kinri Energy | Author：Kinri Energy | Issuing Time：2024.05.24
The application of switching power supplies in the industrial field is very extensive and can be said to be an indispensable part. Many large equipment have high requirements for choosing industrial switching power supplies. Next, let's take a look at the high requirements for switch mode power supplies in the industrial field?


Industrial Control System Power Supply

1.Firstly, it is important to choose the appropriate input voltage standard.

2. Choose the correct and appropriate power. In order to extend the service life of the power supply, a model with a 30% increase in output rated power should be selected.

3. Consider load characteristics. The increased load is an electric motor, light bulb, or capacitor load. The current is high during startup. It is necessary to choose a suitable power source to prevent overload. If the load is an electric motor, please consider reverse voltage during shutdown.

4. For other requirements, please consider the temperature of the power supply working environment and whether there is a rated auxiliary cooling device. If the ambient temperature is too high, it is necessary to reduce the output power. Derating curve of environmental temperature on output power.

5. Select various functions according to usage needs:

Switching power supply protection functions: overvoltage protection (OVP), overheating protection (OTP), overload protection (OLP), etc.

Usage functions: signal function (normal power supply, power off), remote control function, telemetry function, parallel function, etc.

Special features: Power Factor Correction (PFC), Uninterruptible Power Supply (UPS).

6. Select the required safety regulations and electromagnetic compatibility (EMC) certification for switch mode power supplies.
