HVB300

High Voltage Test Interface for Dielectric, Conductivity and Impedance Two-Electrode Spectroscopy for the Alpha-A Modular Measurement System
HVB300

The HVB 300 extension test interface for the Alpha-A modular measurement system features dielectric, conductivity, impedance 2 electrode spectroscopy at dc and / or ac voltages up to ±150 Vp. 

Like all Alpha-A test interfaces, the HVB 300 features high general purpose performance. In addition, it is optimized for for broadband high voltage measurements of low loss dielectrics.

HVB 300 is especially recommended for dielectrics, semiconductors or electronic components at high AC and/or DC voltages for For material measurements, operation with the Novocontrol High Voltage Sample Cell is recommended.
