POWER FACTOR CORRECTION CIRCUITRY The advanced design for ac inputs (P0922YU) provides an active sinusoidal current profile for nearunity controlled power factor.The power supply operates as a constant voltage source with maximum load ratings as listed in the specifications. If load current attempts to exceed greater than 110% of maximum current at the rated 25C load, the output voltage begins to decrease toward zero, thereby limiting the current delivered to the load. Upon removal of overload, normal operation resumes.
OVERVOLTAGE SHUTDOWN
Automatic shutdown occurs if operating conditions cause excessive output voltage. After the occurrence of an overvoltage shutdown, input power must be interrupted to re-establish the output. After the cause of the shutdown has been removed, the shutdown circuit resets in less than 30 seconds after the removal of input power.The power supplies are UL and UL-C listed (to UL 1950) as having a Safety Extra Low Voltage (SELV) and can be used in Division 2 and Zone 2 applications.
POWER FOR EXTERNAL FIELD DEVICES
The actual amount of power required in a DIN rail mounted subsystem depends on the number of Fieldbus Modules (FBMs)/Fieldbus Communication Modules (FCMs)/Field Control Processors (FCPs) being powered, the types of termination assemblies used, and whether internal or external powering is used for the individual field device(s). The FPS400-24 can also be used as a field power supply to power external field devices. However, for system integrity field devices and DIN rail baseplates should not be powered from the same FPS400-24.
