Applications

Decade inductance boxes are used for designing, testing and calibration of test equipments, inductive filters, oscillators, frequency analyzers, etc. It is also used as a temporary substitute for finding the optimum value of required inductance in audio and low radio frequency equipments. The main function of these instruments are to create a specific inductance value by selecting the rotary switches . inductance range from 100H to 10H with a general accuracy of 1%.

Description

A wide range of accurate inductance are available through single row of switches, which allows to read the selected value directly from the position of CONTROL KNOBS. These Decade inductance boxes are designed to get accurate inductance by selecting an individual range any where through the bottom mounted shrouded sockets.
Inductance are made of precision winding on ferrite pot core to get precise value. Specially designed bobbins holding pot core mounted on PCB to get stable values.
Use of professional grade rotary switches of wiping & self cleaning contacts of silver plated copper alloy with excellent dielectric material. These switches are designed for very low contact resistance and high insulation. Inductance are enclosed in metal cabinet or a specially designed aluminium extruded body with multi-color printed polycarbonate membrane on front panel. Specially made quality hardware components provide easy operation and elegant look . High accurate testing and measuring instrument being used to calibrate these decade boxes
