FS SERIES

The FS Series power supplies are provided with internal input over-voltage

and over-temperature protection. In the event the input voltage or internal

temperature exceeds a preset level, the power supply will be temporarily

disabled. A TTL-compatible, latching alarm signal transitions from low to

high to indicate an alarm condition has occurred. Sustained presence of an

input over-voltage may damage input components. The user should respond

to the alarm by removing the potentially damaging input.

Once all alarm conditions are cleared, the power supply will resume normal

operation. The alarm output signal will remain high to indicate an alarm

event has occurred. To clear the alarm output, the +5V logic input must be

toggled low for >250ms, then returned high.

The protection circuits are powered by the +5V logic input voltage and

draw <25mA.

SMART FEATURES

NOTE: The no-load curve may be as much as 200% x the full-load curve. Varies per model.
