MZ*2 series of PTC thermistor is a new energy-saving and
intelligent preheat starting PTC thermistor 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!
Advantages:
1.Preheating soft start components can greatly increase the
switch times and service life,and quality is reliable;
2.No temperature-increasing or power-consuming after
preheating;
3.Can prolong lamp life *0 times more;
4.PTC switching life can pass over **0,**0 times;
5.Resistance doesn't drift in normal temperature;
Â
Choose guidelines of intelligent preheat starting PTCR for
electronic ballasts and energy-saving lamps:
1.PTC thermistor Curie temperature can not be too low that
above **0℃ is advisable because high temperature of the
energy-saving lamps in the work.Otherwise time delay of start
will be too short that could not rise to preheating effect;
2.when single capacitor in the start line,PTCR is required to
withstand high voltage,usually above **0 V;
3.PTC thermistor with resistance of high rate can get a huge
increase in reliability,which should be chosen preferentially
in the meet under the premise of startup behavior;
4.Must consider in low-temperature start, at low temperatures,
the PTC thermistor heat balance resistance relatively low, may
cause tubes don't start;
5. PTC thermistor switch life over *****0 times is much better;
6.Preheat time can't less than 0.4 seconds;
7.the power consumption of PTC thermistor need conform to the
relevant provisions.
Remarks: Many specifications for choice,and samples&orders
can be custom made per customers' requirement.Â
