The KVD-500 Series is a cost-effective, three-terminal, Kelvin Varley Voltage Divider that uses thumbwheel switches

Where most other Kelvin Varley Voltage Dividers only offer you a imput resistance of 1 kΩ, 10 kΩ, or 100 kΩ, IET can custom make the KVD-500 Series at any resistance or any resolution you require.


If you are looking for a reasonably priced, high quality solution the KVD-500 Series is a excellent option.
