All specifications apply over specified input voltage, output load, and temperature range, unless otherwise noted.

PARAMETER

CONDITIONS/DESCRIPTION

Reports information and monitors alarm functions

PS Seated Signal

Contact closure to GND

PS Remote Shutdown

TTL compatible signal, open collector. Power supply enabled at Low or TTL "0" (e.g. by connecting of

pin 22 to 0V or GND), and inhibited to latching mode** at High or TTL "1", or leave it open.

Supervisory AC input voltage;

Pre-warning time >6 ms

Supervisory under- and overvoltage pre-ORing diode of V1

Indicates if unit is operating normally or in overtemperature, Pre-warning time >10 ms

Indicates if fan is operating or has failed

Current Share

Droop load characteristic for V1 and V2

Status Indication

LEDs: DC OK (green), AC OK (green)

NOTE:

** (1) Standard FNP300 models (without "H" at the end of part number) have latching inhibit function, i.e., once PSU is inhibited, it needs

input power re-cycle to allow using enable state again.

(2) FNP300 variants marked with "H" character do have non-latching inhibit function so there's no need to re-cycle input power when

enabling unit after inhibit state.

All specifications apply over specified input voltage, output load, and temperature range, unless otherwise noted.

PARAMETER

CONDITIONS/DESCRIPTION

Fan speed control

4 fan speed levels depending on inlet temperature

µC supply voltage in-/output

(Pin 10)

If unit is operating: 5 to 7V is provided at pin 10.

If unit is NOT operating, pin 10 is input from a parallel connected unit for µC supply.
