Function

Description

14

TEMP_ALARM

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.

5

DC_OK

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.

6

V_TRIM

Connection for output voltage trimming of FPS1000 unit. The voltage can be trimmed within
its range specifications.

9

+12V_AUX

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.

10

CS

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.

3

SIGNAL_RETURN 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.

8

+SENSE

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.

11

AC_FAIL

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.

Serial Data used in the I

2

C interface option. Refer to the I

2

C interface description in the

FPS1000 Instruction Manual.

7

-SENSE

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.

12

ON/OFF_1 (*1)

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).

- LOCAL SENSE

+ LOCAL SENSE

ON/OFF_2 (*1)

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

ON/OFF LOGIC

SELECT

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.

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.

Note:
*1: On/Off_1 and On/Off_2 are reversed logic inputs.
