The Power Diodes consists of six power diodes mounted in a half-size EMS enclosure. Each individual diode is protected against overcurrent and short-circuits by a thermal-magnetic circuit breaker. All the anodes and cathodes of the diode are terminated on the front panel by color-coded, 4 mm safety banana jacks. The diodes are interconnected in three groups of two, i.e., one group for each phase of the power supply. To reduce the number of external connections on the front panel, the upper cathodes can be connected together as well as the lower anodes, through the use of a toggle switch.
