TR1-5/2 (original box)

Description

Thyratron TR1-5/2 continuous operation with indirectly heated oxide cathode, designed to operate in rectifier and relay devices with an anode current of not more than 5A at a voltage of up to 2kV.
Works in a vertical position, the output of the anode up.
Cooling is natural.
Ambient temperature from +15 to +45° С.

Deciphering the marking of the thyratron TR1-5/2:
TP – continuous thyratron with heated cathode and filling with mercury vapor;
1 – number of serial number of thyratron development;
5 – a number that determines the average value of the anode current in amperes (A);
2 is a number indicating the maximum anode voltage in kilovolts (kV).
