This National Power Tube is a compact, quick heating thratron designed for motor speed control and welding control applications. It is xenon filled for quick starting and the ability to operate within very wide temperature limits. dc Amperes output (Maximum): 18 16 Instantaneous amperes output (Maximum): 100 160 Maximum time of averaging anode current (seconds): 4.5 Maximum peak inverse volts: 1250 Maximum peak forward volts: 1000 Max. commutation factor (V/usec. x A/usec.) at max. initial inverse voltage of 330 volts: 0.66 Filament heating time (seconds): 60 Typical arc drop at 50 amperes peak (volts): 12 Maximum negative grid voltage before conduction (volts): 100 Maximum negative grid voltage during conduction (volts): 10 Maximum critical grid current (microamps): 10 Ionization time (approx., microseconds): 10 Deionization time (approx. microseconds): 1000 Anode to grid capacitance (uuf) (approx.): 8 Maximum ac short circuit current (amperes): 1000 Ambient temperature limits ( °C): —55 to +75 Member: Machinery Dealers National Associationrule Hours of Operation: Monday - Thursday 9 a.m. to 5 p.m. - Friday - 9 a.m. to 4 p.m. 1311 South Ponca Street - Baltimore, Maryland 21224 Phone (***)-633-2300 or (***)-394-4399 - Fax (***)-633-7737 (We do not proofread any ads submitted by members) |
