Brief Introduction:

MZ 12 series of PTC Thermistor is a new energy-saving and intelligent preheat starting


PTCR for electronic ballasts and energy-saving lamps without temperature-increasing or power-consuming after preheating, which can prolong the on-off time and life of lamps greatly.meanwhile, it overcomes the shortcoming of temperature rising and power consumption which happen after preheat starting of the electronic ballasts and energy saving lamps.It increases luminous flux and lighting efficiency.All of these prove that it can be called another breakthrough revolution in the field of green lumination appliance!

PTC Thermistor Working principle:

When the high frequency shaking circuit loop has been put through, because PTC is in a cold state and Rt is in a low state of resistance, its resistance value is far lower than that of C2, and the light pressure is smaller than that of starting it. Then current through C1, RT forms the loop circuit-preheating filament. Meanwhile, PTC Thermistor is heated to above the Curie temperature, Rt heating temperature exceeding the switch temperature TSW and leaping to the state of high resistance too. Its resistance value is far higher than that of C2, and the current goes through C1, C2, forming the return circuit and causing LC resonance and producing high pressure and lighting the tube. Generally speaking, to delay the preheating time, we should select the relatively lower resistance, taller Tc point and bigger PTC Thermistor.Filament material will be sputtered seriously if the filament of energy-saving lamps starting with high voltage without preheating anymore, cause lamp tubes black and scrap in advance! Use PTC thermistors MZ12 type, the filament will be preheated around 1 second in starting, and then add high voltage to lit the lamp, can prevent black of the tube ends effectively, can also prevent components of lamps and lanterns lines such as audion from impact of starting instant large current and high back voltage, can prolong lamp life 10 times more.
