What are the requirements for parallel expansion of regulated DC power supplies?
The regulated DC power supply adopts high-frequency modulation technology, which is more advanced and improves the speed and efficiency of data transmission. Its main function is to expand the switching voltage and current to achieve a wider voltage and current adjustment range and expand the application range of DC power supply. The current DC power supply control chip uses relatively mature imported components, and the power supply components use recently developed advanced high-performance means to adjust the design of the DC power supply to avoid the influence of the traditional DC power supply due to the asymmetry of the transformer size and operating frequency . Compared with traditional power supplies, high-frequency DC power supplies have the advantages of small size, light weight, and high efficiency, which also enables the size reduction of high-power DC power supplies (also known as high-frequency adjustable power supplies). The adjustable DC stabilized power supply has comprehensive voltage protection, the overvoltage and leakage point can be continuously adjusted and predicted, and the output voltage can be controlled by a contact switch.
Regulated DC power supply
1. After the adjustable DC power module N+M (M stands for power system redundancy) parallel expansion, the technical indicators such as the total power supply of the power system, the voltage effect of the power supply, the load effect, and transition measurement must be kept within the technical indicators required by the system within range.
2. Each DC power module has the function of automatically adjusting the output current.
3. Due to the adoption of redundant technology, if the failure of one power module does not affect the normal operation of the entire power system, the power system must have sufficient load.
4. Do not attempt to modify the internal circuit of the DC power module to ensure high reliability of the power system.
5. For ordinary media buses, the bandwidth is lower to reduce the noise of the network system.
6. Ensure the load distribution of each element of the DC power system. This means that the entire power system should operate as a whole in parallel flow, and the performance of the entire power system should be optimized with parallel arrangement technology.
