Description

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 watts 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 is selected by dialling the value required using the 6 large rotary switches.

This enables precise setting with a clear unambiguous indication. 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.

The 1065 features 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.
