Abstract
A circuit for delivering power to a load at a predetermined voltage and current. The circuit limits the voltage and current available at the load in the event that the load becomes either detached from the circuit or short circuited to facilitate safe operation of the load in an explosive environment such as a paint spray booth. The current is limited by a constant current source and the voltage is limited either by the maximum output voltage from the constant current source or be a zener barrier circuit.
