eBay 5c3s 5ц3с = 5U4G Soviet ussr Rectifier tube Svetlana NEW 2pcs The main distinguishing feature of this lamp is its rather large rectified current (up to 250 mA). The second distinctive feature is the presence of two separate anodes. Main characteristics Height 126 mm, diameter 52 mm. The main electrical parameters: Rated glow voltage (constant or variable) 5 V. The highest glow voltage (constant or variable) 5.5 V. The smallest voltage is the smallest (constant or variable) 4.5 V. Glow current 3.0 ± 0.3 A. Anode voltage rated (constant) 75 V. Rated anode current at anode voltage of 75 V (for each diode) At least 225 mA. The anode voltage is effective 2 × 500 V. Rated rectified current (average value) Not less than 230 mA. The amplitude of the reverse voltage limit is 1700 V. The amplitude of the anode current is 750 mA. Rectified current limit (average value) no more than 250 mA. Load resistance 2 kOhm. The capacitance of the smoothing filter capacitor is 4 μF. Recommended operating modes in two different modes for half-wave AC rectification Parameter Mode 1 Mode 2 Transformer secondary voltage (rms) 2 × 500 2 × 500 Reverse anode voltage (amplitude value), kV 1.2 1.3 Anode current (amplitude value), mA 730 750 Rectified voltage, V 500 570 Rectified current (average value), mA 250 225 Total active resistance in the anode circuit, Ohm 50 50 Ripple filter capacitor capacitance, μF 4 20 Possible replacements It is possible to replace the 5C4S kenotron with two if the rated voltage is not higher than 400 V. The second option is to replace the 5C8S kenotron, which allows a much larger rectified current (420 mA). However, this replacement is not always possible because of the higher glow current in 5c8S: 5 A against 3 A in 5c3S, because of the possible lack of a contact panel for 5c8S, or because of the relatively lower voltage at the anode: 450 V against 500 V, if 5c3S is used in the circuit at maximum permissible operating modes.
