LED waterproof power supply circuit layout |
An electronic transformer buck: This place is inadequate power supply layout transform low power, narrow voltage scale, usually 180 ~ 240V, ripples disturb large.
2, the capacitor buck: This method is simple LED waterproof power grid voltage shaken by the impact of low electrical power, not flashing LED waterproof power supply when using.
Because the circuit through the capacitor buck when flashing use, due to the effect of charging and discharging, after LED waterproof power supply current of great moment, simply damage the chip.
3, PWM control of switching power supply: current terms, PWM control method depicted LED waterproof power is unmatched ambition, since the output voltage or current of this LED waterproof power supply is very stable.
Guangzhou, a sharp Optimax Technology Co., Ltd. (www.crilite.com) - specialized in producing LED waterproof power supply, LED downlights LED panel lights power supply and other products.
