产品详情
The DVR Series offers a 150 kV and a 300 kV AC/DC model designed with precision resistor/capacitor networks that provide low voltage outputs proportional to the applied high voltage bbbbb. Their 1000:1 and 10,000:1 ratios (respectively) extend the measurement capability of most digital voltmeters and oscilloscopes to 150,000 V or 300,000 V.
The dividers include a switchable low-end impedance to match various metering bbbbbs. Both are suited for waveshape/harmonic analysis using a standard oscilloscope and can be used to measure DC multiplier circuits or AC transbbbbers, limited only by the digital voltmeter (DVM) connected as the metering device.
They are not designed for impulse or square wave applications.
Features:
- Designed to be used with most DMMs and oscilloscopes
- Can be used as a reference for in-house high voltage calibrations
- No external power source required
- Switch 10 MΩ or 1 MΩ low end impedance
- Designed to be less susceptible to electrical field proximity and interference
- Lightweight and transit sturdy assembly
- Custom case for DVR-150 available

DVR-150 & DVR-300高压分压器
0-150 kV和0-300 kV交直流电压
DVR-150 和 DVR-300 为两款精密电阻器/电容器高压分压器，能够将输入的高压按比例输出低压。二者的分压比分别为1000:1和10000:1，从而将大部分数字电压表和示波器的测量能力扩大到了150 kV或300 kV。分压器包含一个可切换的低阻抗，以适应不同测量输入。
利用一个标准示波器，这两款分压器均适用于波形或谐波分析，并能用于测量直流倍增器电路或交流变压器，仅受作为测量装置使用的数字电压表（DVM）的限制。这两款分压器不适用于测量脉冲波或方波。
• 可作为内部高压校准的参照；
• 设计与大多数数字万用表或示波器一起使用；
• 无需外部电源；
• 10兆欧/ 1兆欧低阻抗切换开关
• 体积轻巧，结构坚实 适合运输
• 不易受 相邻电场的干扰影响
