Power selection recommendation

The power supply solution of the entire DTU system mainly considers the problem of uninterrupted power supply, so it needs a power supply form of dual power supply, the mainstream power supply is generally composed of two parts, one part is a high-power 300W or 500W AC/DC charging power supply, the power supply is generally two outputs, one way to power the board after the stage. On the one hand to the rear stage of the battery or super capacitor to charge; The other part is the battery or super capacitor, which is mainly in the case of mains power failure, the normal operation of the entire system. In addition, the power grid has harsh requirements for EMC, especially for surge, which needs to meet the requirements of level 4. If both the main power supply and the battery are powered off, the power-off retention time of the system is greater than 500mS.

According to the above application description, we recommend the wiring power supply of Jin Shengyang MBP500-2A54D54, which has the battery charging function and can charge 48V lead-acid batteries; Industrial grade operating temperature: -40℃ ~ +70℃; 2500VAC isolation voltage; Large instantaneous overpower of 540W; EMC performance; Wired installation.

In addition, if the voltage value of the lead-acid battery is 24V, the wiring power supply of Jin Shengyang Company’s MBP300-2A27D27 can be used to charge the 24V lead-acid battery, and the steady-state power can reach 351W.
Power supply is an indispensable part of electronic equipment, and its performance is directly related to the technical indicators of electronic equipment and whether it can work reliably. At present, the commonly used DC power supply is divided into linear power supply and switching power supply according to the working mode of power tube. Linear regulated power supply is also known as series regulated power supply, circuit technology is relatively mature. It has the advantages of low ripple and stable voltage. However, because the power frequency transformer is used and the adjustment tube works in the linear amplification area, the volume and weight are large and the efficiency is low. Switching power supply regulator works in the frequency switching state, the power loss is small, and the use of small volume frequency transformer instead of bulky power frequency transformer to achieve voltage conversion and grid isolation.
In order to solve the above problems of traditional PWM converter, resonant, quasi-resonant, multi-resonant and PWM converter with soft switch can be used. These converters absorb and utilize parasitic parameters in PWM converter or external inductance and capacitance as resonance parameters, so that the power switch in the converter is zero
