保護用戶和儀器

2290系列電源和2290-PM-200型保護 模塊可使用戶和儀器免遭危險電壓損害。 當(dāng)高壓測試夾具檢修門打開時，利用電源 內(nèi)置的互鎖電路，可以確保輸出電壓禁用。 此外，2290系列所有電源都具有低壓模擬 輸出，允許對高電壓和輸出電流進行安全 監(jiān)控。

在高壓電路中使用低壓測量儀器時， 保護模塊可以將儀器電壓安全地鉗位在 200V值，即使待測器件(DUT)擊穿。 因此，2290系列電源2290-PM-200型保護 模塊和吉時利附件提供了構(gòu)建安全、高壓 測試環(huán)境所需的一切。

The 2290 series high voltage power supply is useful for high voltage device and material testing as well as high energy physics experiments. Type 2290-5 5kV power supply voltage output up to 5000V, type 2290-10 10kV power supply voltage output up to 10,000V. Type 2290-5 power supply has 5mA current capacity, type 2290-10 power supply has 1mA current capacity. These sources can measure the output voltage with A voltage resolution of 1V or the output current with A current resolution of 1 A. In addition to the voltage and current output display, the third screen can display one of the following four Settings: output voltage, voltage limiting, current limiting, and current tripping. These values can be set via the front panel keyboard. These Settings can also be programmed via the ieeee-4888 interface, or the output voltage can be set via an analog control voltage.

Low noise ensures high accuracy and low level measurement

Low output noise is essential for leakage current or high resistance measurements using highly sensitive measuring instruments. Maximum output wavelength of model 2290-10 power supply is lower than 1VRMS. Maximum output wavelength of model 2290-5 power supply is less than 100mVRMS. The model 2290-5 power supply can reduce the maximum output ripple to 3mVRMS by selecting two internal filters. These two power supplies provide extremely low noise levels for accurate picoampere-level current measurements by highly sensitive measuring instruments.

Protect users and equipment

The 2290 series power supply and the 2290-pm-200 protection module protect users and instruments from dangerous voltages. When the access door of the high-voltage test fixture is opened, the interlocking circuit built into the power supply can ensure that the output voltage is disabled. In addition, all 2290 series power supplies have low voltage analog outputs, allowing for safe monitoring of high voltages and output currents.

When using a low-voltage measuring instrument in a high-voltage circuit, the protection module can safely clamp the instrument voltage to the maximum value of 200V, even if the device under test (DUT) breaks down. Therefore, the 2290 series power supply 2290-pm-200 type protection module and ghisley accessories provide everything needed to build a safe, high-voltage test environment.
