Abstract: An AC and DC input power supply includes an AC power supply circuit and an AC input for receiving a range of AC input voltages. A rectifier circuit is connected to the AC input. An isolation output transformer has first and second primary winding terminals and a low voltage winding section for connecting to a DC voltage input that is lower than the range of the DC voltage that is rectified from the range of AC input voltages. The rectifier circuit is connected to the first primary winding terminal of the isolation output transformer. A transistor is connected to the second primary winding terminal of the isolation output transformer. The DC power supply circuit includes a DC input that is selectably connectable between the first primary winding terminal when the voltage input to the DC input connector is a nominal DC voltage that is within the range of the DC bulk voltage and the low voltage winding section when the voltage input to the DC input is lower than the range of the DC bulk voltage.

Abstract: A power limiting circuit for power supply that is controlled by a power supply control module includes a shunt regulator having a reference input operatively connected to a voltage input that receives a voltage representative of the power supply control module connected thereto. The shunt regulator is biased on when the voltage at the reference input increases above a reference voltage established at the voltage input. A transistor is operatively connected to the shunt regulator and to an output operatively connected to the power supply control module and has a voltage that is representative of voltage operating the power supply control module. The transistor is biased on from the shunt regulator such that the shunt regulator and transistor form a latch when the voltage at the output reduces below an off voltage level to turn off the power supply, dropping the input voltage, and restarting the power supply in a restart cycle.
