What Are The Correct Ways To Use The Din Rail Switching Power Supply?

1. The AC voltage specifications that can be used by rail 24v power supply are 110VAC, 220VAC and 380VAC. Therefore, before switch mode power supply is powered on, carefully check whether the connected voltage is correct and consistent with the input voltage of smps power supply.
2. Do not load before the first power-on. First check whether the output voltage of ac dc switching power supply is the same as the switching power supply 12v of the connected device to avoid damage to the connected device.
3. Before using this switching power supply 100 240v, confirm whether the ground wire is connected, and mark the specific location of the ac dc switching power supply sp2 a ground wire in the figure.
4. Before and after use, switching power supply 24v should be placed in a well-ventilated and heat-dissipating place.
5. The determination of the output current of rail 24v smps is closely related to the environment. It is determined according to the rated standard current of the equipment provided by rail 12 volt switching power supply or the average current value measured by the multimeter. And in the case of high ambient temperature, poor air flow conditions, and too many inductive loads, be sure to prepare 20-30% more current margin.
6. The input power of rail switching adapter input 100 240v output 12v is generally determined by the rated input power of rail switching power supply 100 240v 50 60hz output 24v, which determines the rated marked power of the supplied equipment. However, if the rated power of the specific equipment is not clear, it can also be modified to obtain the power based on the product of the rated current and voltage of the equipment, that is, current x voltage. It should be noted that when users select 48v switching power supply power, it should be greater than 15-30% of the actual power and peak power.
7. Determination of the number of DC circuits output by rail okin ac dc switching power supply: rail smps 12v generally has S-single group, D-double group, T-three groups, Q-four groups of circuit output.
8. Rail switching power adapter 12v has overcurrent, overheating protection and fan heat dissipation protection functions. Therefore, it is necessary to select the most suitable one according to the actual use situation, so as to enhance the reliability and stability of the system engineering.
9. There are many types of rail 24 volt switching power supply: industrial iron shell type, rail type, LED outdoor rainproof type and waterproof type, etc. Please choose according to the actual daily application needs.
