T o mate FPS1000 series to the load circuitry , use female connector PCIB24W9F400A1-S1031, Positronic connector . Refer to T able 3-4 and to the Outline drawing in chapter 2 for the connector pinout description.
11 CHAPTER 4 FUNCTIONS AND FEA TURES 4.1 Input V oltage Range Input voltage is single phase 85~265V ac (47~63Hz). The power supply can be operated also with a DC input voltage, 120~330VDC but the safety approvals apply to the AC voltage only . Input voltage which is out of the specifications might cause damage to the unit.
12 4.8 DC_OK signal An open collector output provides a low output voltage detection signal. The open collector output is on when the output voltage is higher than 80%+/-5% of the rated output voltage of the power supply .
13 Fig 4-6 4.1 1 Remote Sensing The Remote sensing compensates voltage drop on the load wiring. The maximum voltage drop on each wire is 1V , however , it is recommended to minimize the voltage drop on the load wires to improve the response to load current changes.
14 Fig 5-1: single load connection, local sensing Fig 5-2: Remote sensing, single load. CHAPTER 5 BASIC CONNECTIONS FOR OPERA TION 5.1 Connecting single load, Local sensing Local sensing is suitable for applications where load regulation is not critical.
15 Fig 5-4: Multiple loads connection with distribution terminal 5.4 Multiple loads connection with distribution terminals If remotely located output distribution terminals are used, the power supply output terminals should be connected to the distribution terminals by a pair of twisted or shielded wires.
16 CHAPTER 6 P ARALLEL AND SERIES OPERA TION 6.1 Parallel operation Up to 8 FPS1000 units of the same output voltage rating can be connected in parallel. By connecting the CS signal between the paralleled units, automatic current balance is achieved, with +/-10% accuracy .
17 Fig 6-3: Signal Return connection at parallel operation Fig 6-4: Remote On/Off control at parallel operation 6.1.3 Signal Return bus at parallel operation The Signal Return of each paralleled unit can be connected together to form a common Signal Return bus.
18 Fig 6-6: Series connection for Bipolar output voltage 6.2 Series operation T wo units can be seriesly connected to increase the output voltage or to create a bipolar voltage source. It is recommended to connect diodes in parallel with each output to prevent reverse voltage in case of failure in one of the power supplies.
