   An 8-plate 160 V 450 mA Federal brand selenium rectifier. A selenium rectifier is a type of metal rectifier, invented in 1933. [1] They were used in power supplies for electronic equipment and in high-current battery-charger applications until they were superseded by silicon diode rectifiers in the late 1960s.

4. Rectifier - Wikipedia

   en.wikipedia.org/wiki/Rectifier

   Typically these rectifiers were made up of stacks of metal plates or washers, held together by a central bolt, with the number of stacks determined by voltage; each cell was rated for about 20 V. An automotive battery charger rectifier might have only one cell: the high-voltage power supply for a vacuum tube might have dozens of stacked plates ...

5. Metal rectifier - Wikipedia

   en.wikipedia.org/wiki/Metal_rectifier

   A number of rectifier discs would need to be used in series to provide an adequate reverse breakdown voltage figure – a bridge rectifier for a 12V battery charger would often use 12 metal rectifiers. Selenium rectifiers were generally more efficient than metal-oxide types, and could handle higher voltages.

6. Charge controller - Wikipedia

   Pump Express Plus supports elevated voltage levels of 7, 9 and 12 volts, whereas the specification for Quick Charge 2.0 lacks the 7-volt level. A 20-volt level was added in a revision named "class B" of the specification. [12] [13] The voltage range of the successor Pump Express Plus 2.0 is between 5 volts and 20 volts, with 0.5 volts steps.
