Part NumberPIVMaximum CurrentSurge CurrentSize InchesStyle
20 KV 3.0 A 400 A 7.5 x 1 x 1 Single
Encapsulated High Voltage Single String Rectifier with heavy duty components designed for the most demanding of services. This assembly uses 6 Ampere rated diodes. Each diode is bridged with a resistor to divide transients equally across each component. Conservatively rated at 3 Amperes and 20,000 Volts PIV. Each end is slotted for #6 screw mounting

26 KV 0.8 A 60 A 4.8 x .63 x 1.5 Double
Encapsulated High Voltage Rectifier in a voltage doubler configuration. Uses 2.5 Ampere diodes encapsulated in thermally efficient epoxy which is then cemented into an aluminum channel for mounting. Rated 10,000 Volts PIV per section, or 20,000 Volts PIV for the whole assembly. This unit is rated 0.8 Ampere average. A slot is punched in each end of the channel for a #6 mounting screw.
