Product Introduction
Overview of High Frequency Switching Power Supply and DC Switching Power Supply:
The high-frequency switching power supply mainly uses imported IGBT modules as power devices and a main high-frequency transformer made of nanocrystalline materials. It adopts full bridge full wave output, PWM control, closed-loop sampling, soft start, overvoltage, overcurrent, and overheating protection
High frequency switching power supplies work with high stability, reliability, and safety. The system has a fast response speed (microsecond level) and strong adaptability to changes in grid power and load. The output accuracy can be better than 1%.
1， switching power supply Voltage stabilization accuracy
Source effect: ≤ 0.5% rated value (output voltage change rate caused only by ± 10% variation in input source voltage); Time drift: ≤ 0.3% of rated value (only the output voltage change rate caused by the continuous working time of the power supply exceeding 8 hours); Temperature drift: ≤ 0.04% rated value/℃ (only due to the output voltage change rate caused by environmental temperature changes within the range of power supply usage environment temperature); Load effect: ≤ 0.2% rated value (only the rate of change in output voltage caused by the change in output current from zero to rated value).
2, switching power supply Steady current accuracy
Source effect: ≤ 0.5% rated value (output voltage change rate caused only by ± 10% variation in input source voltage); Time drift: ≤ 0.3% of rated value (only the output voltage change rate caused by the continuous working time of the power supply exceeding 8 hours); Temperature drift: ≤ 0.04% rated value/℃ (only due to the output voltage change rate caused by environmental temperature changes within the range of power supply usage environment temperature); Load effect: ≤ 0.2% rated value (only the rate of change in output current caused by the change in output voltage from zero to rated value).
