5C4S (figural)

Kenotron 5C4S two-anode low-voltage, designed to rectify alternating current of industrial frequency 50 Hz. Can be used in rectifiers for voltage rectification up to 400 Hz.
Works in any position. Kenotron 5C4S is produced in glass design. Socle 4-pin with octal with a key.
The scheme of application of the kenotron 5C4S (1/2 5C3S) is similar to the scheme of application of the kenotron 5C3S.

5 – a number indicating the rounded value of the tube filament voltage in volts;

C – a letter that determines the type of tube: C – low-power kenotron;

4 – the number of the serial number of the development of this type of tube;

S – a letter characterizing the design.
