FPS-S1U Instruction Manual

10.7.3 Making the load connections

!WARNING

Hazardous voltages may exist at the outputs and the load connections when using a power supply with a rated output greater than 40V. To protect personnel against accidental contact with hazardous voltages, ensure that the load and it's connections has no accessible live parts. Ensure that the load wiring insulation rating is greater than or equal to the maximum output voltage of the power supply.

The load wires should be properly terminated with terminals securely attached. DO NOT use unterminated wires for load connection at the FPS-S1U.

1.Mounting brackets. Use M6x12 screws to fix the FPS-S1U to the rack.

2: DB25 connector for control and monitoring signals.

3: Output voltage terminals. Use M6x16 screws and M6 lug to connect the load wire. The recommended tightening torque is 42~56Kgf.cm.

4.DIP switch for I2C option address setting. Refer to Chapter 14 for details.

5.IEC320 AC inlets, shown for FPS-S1U rack. For FPS-S1U/P, there are no IEC320 inlets on the rack.

Function

Description

1

V_TRIM_B

Connection for output voltage trimming of FPS1000 unit "B". The voltage can be

 

 

trimmed within its range specifications.

 

 

 

2

TEMP_ALARM_B

Open collector signal, referenced to pin 11 (Signal Return). On when the internal temperature

 

 

of FPS1000 unit "B" 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.

 

 

 

3

DC_OK_B

Open collector signal, referenced to pin 11 (Signal Return). On when the output voltage

 

 

of FPS1000 unit "B" is higher than ≥ 80%+/-5%. The maximum sink current: 10mA

 

 

and the maximum external voltage is 15V.

 

 

 

4

TEMP_ALARM_A

Open collector signal, referenced to pin 11 (Signal Return). On when the internal temperature

 

 

of FPS1000 unit "A" 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

ON/OFF_A

Turns the output of FPS1000 unit "A" to On and Off by electrical signal or dry contact

 

 

between pin 5 and pin 11 (Signal Return). 0~0.6V or Short: On, 2~15V or Open:

 

 

Off. The maximum source current is 2.6mA.

 

 

 

6

DC_OK_A

Open collector signal, referenced to pin 11 (Signal Return). On when the output

 

 

voltage of FPS1000 unit "A" is higher than Vout ≥ 80%+/-5%. The maximum sink

 

 

current: 10mA and the maximum external voltage is 15V.

 

 

 

7

V_TRIM_A

Connection for output voltage trimming of FPS1000 unit "A". The voltage can be

 

 

trimmed within its range specifications.

 

 

 

8

+12V_AUX

Auxiliary voltage output, 11.2~12.5V, referenced to pin 11 (Signal Return). The

 

 

maximum load current is 0.25A. This output has built in Oring diode and is not controlled

 

 

by the On/Off control.
