Riley Secures DC Power Order from U.S. Aerospace Company (10/25/06)
The project included four Westinghouse air-cooled, silicon diode transformer rectifiers, each with a 6000 amps/36 volts capacity. They were fitted with a new Thyristor control system, enabling them to work as one "master" and three "slave" units in parallel, delivering 0-24000 amps/0-36 volts of continuous power. In addition to the installation of new controls and general refurbishment, the rectifiers had to undergo a rigorous testing procedure at Riley Industries workshops prior to shipping to the U.S., the company reports. Other safety modifications made to the units included input isolators and contactors, current limiting chokes, voltage surge suppression and thermal overload relays.
