Application of DC Loads in DC Power Supplies
In circuits where DC power supply is used as the output terminal, filtering capacitors are usually connected in series to filter AC components, making the DC power supply smoother and cleaner. When switching power, a huge electric shock can cause a short circuit near it, which is the load test of DC power supply components. To test the DC performance using capacitors, a load test must be conducted.
When using a direct output source to test ordinary capacitors, two obvious problems may occur: firstly, excessive short-circuit current can damage unprotected capacitors, causing damage; Secondly, the load characteristics of capacitors are independent and cannot simulate the switching process when the load actually switches from current to stable output.
At present, the vast majority of simulated DC loads on the market are essentially close to circuit impedance changes. The high-speed intelligent simulated DC load designed and manufactured by Jishili has capacitive characteristics, which can simulate real DC coupling conditions and determine the performance of the power supply. The DC load current can reach an instantaneous current of up to 2000a, which is also possible for sudden high currents.
The intelligent analog DC power supply has all protection functions. In order to prevent the power supply and load from being affected by overvoltage, the simulated load adopts an automatic current cut-off protection method. If the load is continuously monitored and the ambient temperature is too high, causing heat accumulation when the temperature is too high, the protective device will automatically shut down.
Intelligent simulation loads can be programmed and modified according to actual needs. Through this method, fully automatic simulation and testing of DC power supply can be carried out. It doesn't require people to adjust the load, saves time and energy, and won't make mistakes. As a high-tech research and production enterprise specializing in high DC output and intelligent load replacement, our company has passed the dual software certification of the Ministry of Information Industry and ISO9001 international quality system. Since its establishment, our company has been focusing on the research and development of intelligent power supply production.
