With the increasing use of new energy sources such as solar systems, large-scale equipment has higher requirements for the selection of industrial switching power supply. So how to choose the industrial switching power supply? What are the precautions in the use process? Let's take a look today.
Firstly, the appropriate input voltage specification should be selected.
Choose the right power. In order to increase the working life of the power supply, a model that exceeds 30% of the output power should be selected.
Consider the load characteristics. If the load is motor, bulb or capacitive load, the current is large at the instant of start-up. So it is necessary to select the appropriate power supply to avoid overload. If the load is motor, it should be considered that there will be voltage reversal during shutdown.
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. In the case of excessively high temperature, the power supply needs to be derated, because the ambient temperature derates the output power.
(1) Protection functions: over voltage protection (OVP), over temperature protection (OTP), overload protection (OLP), etc.
(2) Application functions: signal function (normal power supply, power failure), remote control function, telemetry function, parallel connection function, etc.
(3) Special features: power factor correction (PFC), uninterruptible power supplu(UPS)
Select the industrial switched mode power supply which conforms to the safety regulations and EMC certification.
Before using the power supply, we should first determine whether the specifications of the input and output voltages are consistent with the nominal values of the power supply used.
Before power-on, carefully check whether the input and output wires are connected correctly to prevent damage to the industrial innov switching power supply.
The industrial switching power supply should be firmly installed, carefully check whether there is contact between the mounting screws and the power board device, and measure the insulation resistance of the shell and the input and output to prevent electric shock.
Check carefully whether the grounding terminal is grounded to prevent the safety in the use process, and to reduce certain interference.
Multiplex output power is generally divided into main output and auxiliary output. The main output characteristic is better than the auxiliary output. In order to ensure the output load adjustment rate and output dynamic index, it is generally required to carry at least 10% of the load per channel. If use the auxiliary output instead of the main output, the main output must be loaded with appropriate false loads. Refer to the specifications of the relevant models for detailed parameters.
Remember not to switch on and off frequently, which will affect the life of power supply.
The working environment of the power supply and the degree of loading will also affect its life.
It's better for power suppliers to help select power products suitable for users'equipment.
If conditions permit, it is suggested that variable switching power supply manufacturers design switching power supply professionally according to the conditions of the equipment itself and the environment in which the equipment is located.
The above is our summary of the selection of industrial adjustable switching power supply and the matters needing attention in the use process. If you have any questions, please contact us and we will give you a detailed introduction.
