Power-Mox Precision Power Thick Film High Voltage/High Resistance Tubular Non inductive version shown The heavy duty construction of the Power-Mox series make them durable in most high voltage industrial applications. This product is well known for its high voltage ratings, low voltage coefficients, very high ohmic values, and resistor divider options. Terminations can be selected to adapt to most mounting schemes.
