Abstract
A housing for enclosing a power supply circuit board assembly of the type used in programmable logic controllers is disclosed. Through the use of an adapter plate, the housing can accommodate a wide variety of power supply circuit boards that have multiple input and output components that must be accessible to the outside of the housing. Incoming power is supplied through a terminal block on the front of the housing and output power is presented to an edge connector for supplying control voltages directly to the backplane of a programmable logic controller. A hinged side wall provides easy access to the power supply circuit board and the components on it and slots on the top and bottom of the housing provide venting for cooling the components.
