Quick Tips on Waterproof Power Supplies — How do you step down the voltage in an LED waterproof power supply? Let’s learn together! 1. Voltage Reduction Using Resistors in LED Waterproof Power Supplies: This method relies on resistors to reduce voltage. However, it is highly susceptible to fluctuations in grid voltage and is not easy to design as a stable power supply. The voltage-reducing resistor consumes a significant amount of power, which greatly increases the overall cost of the LED waterproof power supply. As a result, this type of power supply has very low power output and relatively poor system reliability. 2. Voltage Reduction Using Resistors and Capacitors in LED Waterproof Power Supplies: While this method improves the overall performance of the LED waterproof power supply, it still suffers from issues. During flashing, the charging and discharging of the capacitor cause extremely high instantaneous currents through the LED, easily damaging the chip. Additionally, this method is sensitive to fluctuations in grid voltage, resulting in low power efficiency and poor reliability. 3. Voltage Reduction Using Electronic Transformers in LED Waterproof Power Supplies: This method offers lower power output, but significantly improves the physical characteristics of the LED waterproof power supply. The voltage range is also relatively narrow, typically between 90V and 260V, and the ripple interference is considerable. Have you all learned these little tips?
Quick Tips on Waterproof Power Supplies
— How do you step down the voltage for an LED waterproof power supply? Let’s learn together now!
One, LED waterproof power supply Resistance-based voltage reduction method: This method is significantly affected by fluctuations in grid voltage and is not easily used to create a stable power supply. The voltage-reducing resistor dissipates a substantial amount of power. Proper application of LED waterproof power supplies can greatly increase the overall cost-effectiveness of the product. Therefore, this type of power supply has very low power output and relatively poor system reliability.
II. LED Waterproof Power Supply: Voltage Reduction Method Using Resistors and Capacitors—By employing capacitive voltage reduction, the overall performance of the LED waterproof power supply is significantly improved. However, during flashing, due to the charging and discharging effects, the instantaneous current passing through the LED can be extremely high, easily damaging the chip. Moreover, such power supplies are highly susceptible to fluctuations in grid voltage and suffer from low power efficiency and poor reliability.
Three, LED waterproof power supply Voltage-reducing method for electronic transformers: The power supply has lower wattage, the physical specifications of LED waterproof power supplies have improved significantly, and the voltage range is relatively narrow—typically 90–260V—with substantial ripple interference.
