jack cap Posted June 21, 2010 Report Share Posted June 21, 2010 Varo R153 Rectifier? (7803 - wk 3 1978?)Hi There, I wonder if anyone could please help me identify the above component (and a possible source)? It is part of a Woods Ultracon U-100Motor scr cotroller and is the first component across line and neutral (240VAC) after the switch.The device is press fitted into a heatsink and has 3 blade terminals on an insulated post. Line and neutral are across two (with a dead short between them - hence the reason it is tripping the 16amp CB.) The third terminal goes to F2 (Motor field coil) and another point in the unit. Using a multimeter, there is a diode drop from the third terminal to line and also to neutral.A datasheet would be perfect but any information would be appreciated. best regards JAck Quote Link to comment Share on other sites More sharing options...
