TEL-33000 High Voltage Power Supply

This multiple output power supply has four outputs that are primarily intended to supply power for electron tubes and Helmholtz coils. Its own individual analog dial monitors each of the four independently adjustable DC voltages. Each output is stabilized, regulated, floating and galvanically isolated from one another. In addition, the outputs are short circuit proof and secure from external voltages.
