Precautions for purchasing industrial switching power supply
As a part of switching power supply, industrial switching power supply has become more and more widely used in the market with the rapid development of industry technology. Many large-scale equipment have high requirements for the selection of industrial switching power supplies. In this article, our Baoding switching power supply manufacturer will take you to understand the precautions for purchasing industrial switching power supplies.
1. First, select the appropriate input voltage specification;
2. Choose the appropriate power. In order to increase the working life of the power supply, a model with 30% more output power rating should be selected.
3. Consider the load characteristics. The added load is a motor, a light bulb or a capacitive load. When the current is high at the moment of starting up, it is necessary to select a suitable power supply to avoid overload. If the load is a motor, the voltage backflow during shutdown should be considered.
4. In addition, it is necessary to consider the temperature of the working environment of the power supply, and whether there is any additional auxiliary heat dissipation equipment. The power supply needs to derate the output when the ambient temperature is too high, and the derating curve of the ambient temperature to the output power.
5. Select various functions according to the application requirements:
Protection functions: Over Voltage Protection (OVP), Over Temperature Protection (OTP), Over Load Protection (OLP), etc.
Application functions: signal function (normal power supply, power supply failure), remote control function, telemetry function, parallel function, etc.
Special functions: power factor correction (PFC), uninterruptible power supply (UPS)
6. Select the required safety regulations and electromagnetic compatibility (EMC) certification.
