Description
Serial Data used in the I
FPS1000 Instruction Manual.
Serial Clock used in the I
FPS1000 Instruction Manual.
Return for the following control and supervisory signals: On/Off, DC_OK, Over_temperature
Alarm, AC_Fail, Auxiliary 12V supply. The Signal return is isolated from the output terminals.
On/Off control. To use this input, pin#12 and pin#13 must be shorted together.
Short between On/Off_2 to pin#3: Off. Open On/Off_2: On.
The maximum source current is 1.2mA
Open collector signal, referenced to pin 3 (Signal Return). On when the output voltage of
FPS1000 unit is higher than Vout ≥ 80% +/-5%. The maximum sink current: 10mA and the
maximum external voltage is 15V.
Connection for output voltage trimming of FPS1000 unit. The voltage can be trimmed within
its range specifications.
Negative sensing. The -Sense signal should be connected to the negative terminal of the load.
The -Sense and +Sense leads should be twisted pair to minimize noise pick-up effect. The
maximum load wires drop compensation is 1V/wire.
Positive sensing. The +Sense signal should be connected to the positive terminal of the load.
The +Sense and -Sense leads should be twisted pair to minimize noise pick-up effect. The
maximum load wires drop compensation is 1V/wire.
Auxiliary voltage output, 11.2~12.5V, referenced to pin 3 (Signal Return). The maximum load
current is 0.25A. This output is not controlled by the On/Off control.
Current sharing signal. When FPS1000 units are connected in parallel, the CS pins of the units
should be connected to allow current balance between units.
Open collector signal, referenced to pin 3 (Signal Return). On when the input voltage of
FPS1000 unit is ≥85Vrms. The maximum sink current is 10mA, and the maximum external
voltage is 15Vdc.
Turns the output of FPS1000 unit to On and Off by electrical signal or dry contact between
pin 12 and pin 3 (Signal Return). 0~0.6V or Short: On, 2~15V or Open: Off.
The maximum sink current is 2.6 mA (when using pin#12, it should be disconected from pin#13).
Input used to select the On/Off control logic.
Short this input to pin#12 when using On/Off_2 as On/Off control.
Leave this input open when using On/Off_1 as On/Off control.
Open collector signal, referenced to pin 3 (Signal Return). On when the internal temperature of
FPS1000 unit is within safe limit, Off approx. 10°C below Thermal shut down. The maximum
sink current is 10mA and the maximum external voltage is 15V.
When working in local sense mode, connect -Local Sense to -Sense (pin#7).
When working in Remote sense mode, this input should be open.
When working in local sense mode, connect +Local Sense to +Sense (pin#8).
When working in Remote sense mode, this input should be open.
