TESLA RA0007A Light-Emitting Diode
True RMS converter

The RA0007A is a light-emitting diode. It was used to measure the effective value in voltage stabilizers and measuring devices. Its anode current depends on the glowing voltage, and when it is glowed with alternating current, from the effective value of this voltage. Therefore, this tube works as a true RMS (Root Mean Square) converter. It was produced by Czech Tesla, but it was used in devices from different countries.

Incandescent voltage: from 1.4 to 1.7 V
Glow current: up to 3.5 A
Maximum anode voltage: 600 V
Anode current: 0.7 mA
