WMZ11B 型智能 PTC（热敏/压敏复合电阻器）
WMZ11B series PTC Thermistor /Varistor Complex
产品简介（GENERAL）：
WMZ11B 系列是由一个 PTC 热敏电阻 Rt 和一个压敏电阻 Rv 串联而成的复合元件。启动时，
电压高于 Rv 压敏电压，Rv 处于导通状态，其预热启动过程基本是由 Rt 来独立完成的。灯管启
动点亮处于正常工作状态后，Rv 端电压迅速降低到其压敏电压以下，Rv 跃居高阻态，断开 Rt，
从而使零功耗，零温升预热启动得以实现。
WMZ11B 系列 Rt 部分之选型与 WMZ11A 系列基本类似，压敏电阻 Rv 部分之选型主要考虑
Rv 压敏电压应略高于灯管电压、Rv 通流容量足以应付重复通断的启动电流的频繁冲击。
WMZ11B series is a kind of complex components , which includes a thermistor Rt and a
varistor RV in series .when the voltage of the circuit is high than Rv’s vristor voltage at stating ,Rv is at
short state . so the process of preheating is finished almost by Rt independently .after the tube lights and
work normally , the Rv’s voltage will decease quickly to the level under its varistor voltage , then Rv
will change into high-resistance state. So Rt will be at open state and the preheating which is zero
thermal / zero power dissipation will be realized.
The specification of WMZ11B series’ Rt is similar to WMZ11A series. While as to the specification
of Rv, two things must be considered: Rv’s varistor voltage must be higher than tube’s voltage ; Rv’s
max peak current must be able to endure the inrush of repetitive turn over current .
