## Overview

The 3B Scientific Franck-Hertz Power Supply Premium is a high-performance unit designed for educational and experimental use, providing essential voltages for mercury and neon filled Franck-Hertz tubes. It features a built-in DC amplifier for precise current measurement and offers both manual and saw-tooth voltage settings, making it an indispensable tool for physics labs worldwide.

## Description

The quantization of energy and the generation, recording and evaluation of spectra, along with the experimental verification thereof, is included in most of the curricula used around the world. The well known experiment first performed by James Franck and Gustav Hertz in 1913 is critically important in terms of demonstrating discrete energy states in atoms. Power supply unit for operating the mercury filled Franck-Hertz tube, the neon filled Franck-Hertz tube or the critical potential tubes. The equipment provides all the voltages needed to power the tubes and includes a sensitive built-in DC amplifier for measuring collector current. The voltages can simultaneously be read off a display. The accelerating voltage can be set-up manually on the apparatus or set to a saw-tooth wave form. Additional measuring inputs are also available for the anode current and accelerating voltage. Specifications: Filament voltage UF: 0 - 12 V, continuously adjustable, Control voltage UG: 0 - 12 V, continuously adjustable, Accelerating voltage UA: 0 - 80 V, Modes of operation: manually adjusted / saw-tooth, Countervoltage UE: 0 - +/-12 V, continuously adjustable, switchable polarity, Output UY for collector current IE: IE = UA x 38 nA/V (0 - 12 V), Output UX for accelerating voltage UA: UX = UA / 10, Outputs: 4 mm safety sockets, Input: BNC socket. Measures 160mm length by 132mm width by 210mm height.
