1065 High Power Resistance Decade Box

A power resistance decade box designed to meet the standard for industrial use and technical education purposes. Housed in a robust ventilated case, the 1065 can withstand arduous use whilst maintaining accuracy and reliability. 

The slimline design means it takes up minimum bench space and is easily transportable. The high dissipation of 10 W make the 1065 suitable for power electronics applications. The 500 V maximum working voltage is ideal for select-on-test use in high voltage circuits.

Resistance selection is quick and easy via the rotary knobs. Switch contact resistance has been kept to a minimum by the use of multi-wafer switches, each with four parallel, silver-plated, self-cleaning contacts.


  • 0.1 Ω to 120 kΩ
  • 1 % accuracy
  • 10 W total dissipation for any setting
  • Residual resistance < 20 mΩ
  • In-line readout
  • Mechanically/electrically robust
  • Fully screened
1065 inline readout

Simple Operation and In-line Readout

Resistance is selected by dialing the value required using the rotary switches. This enables precise setting with a clear unambiguous indication. 

Each decade is scaled from 0 to 11. This allows a convenient overlap of the set values.

1065 Safety Terminals

Safety Terminals

The 1065 connections are via safety terminals that are compatible with 4 mm shrouded plugs, standard plugs, bare wires, and spade terminals.

These terminals are specifically designed with safety features including limited opening distance and a raised flange around the metal connection surface. This ensures that the clearances are sufficient to make the exposed metal parts touch-proof.
