Description

Mercury-vapour half-wave rectifier for high-voltage rectifier circuits, with rating regimes extending to 25 kV peak inverse and 5 A average current. Promoted maxima are independent published maxima; source gives coupled rating regimes: 25 kV/20 A peak/5 A average and 10-15 kV/12 A peak/3 A average.
