High Pressure Controller LED products: high-pressure type LED product design voltage is AC / DC 220V voltage, LED quantity each loop 36-48 in series generator SX440 manufacturers, each loop current of 20mA or less, limiting in two ways, one species are limiting resistor, in this way a large power resistors are recommended every four LED series with a 1 / 4W metal mold resistance, uniform distribution of heat, which is the most stable and reliable connection; the other is the resistance and capacitance limiting series SX440, which received most of the voltage drop method on capacitors, resistors power consumption, can only be used in a stable long bright state Dongguan generator SX440, if flashing capacitor discharge, but the voltage doubler, LED easily damaged . Any use of the controller LED current limiting resistor must be used the way, LED general one meter each circuit board sx440 surge production, power 5W, three-color power per meter 15W. Common NE112K gradient controller to control the DC 1200W, NE103D 4500W AC load DC load 1500W, if the lamp flashes on the use of multi-unit NE112K, if you only need to use the whole flashing NE103D. If you use a gradient mode, pay attention to the load matching, light distribution characteristics of neon and LED's are not the same, the same circuit can not mix different types of loads connected. When the electric car brushless controller phase brushless electric vehicle controller power and brake failure may refer to brush failed controller troubleshooting be thoroughly excluded in terms of brushless controller, as well as its unique Symptom such phase. Phase brushless electric vehicle controller phenomenon can be divided into the main phase and phase Hall phase two cases. 1) The main phase missing phase detection method can refer to the electric car brush controller Speed ??troubleshooting method to detect whether the MOS transistor breakdown, brushless controller MOS tube down the breakdown is generally one of a pair of phase two MOS tube Meanwhile breakdown, while ensuring at the same time to replace the replacement. Check the measuring points. 2) brushless electric vehicle controller Hall performance phase motor controller does not recognize the Hall signal.
