FPS1000 Instruction Manual CHAPTER 3 FPS1000 POWER SUPPLY INSTALLATION 3.1 GENERAL This chapter contains instructions for initial inspection, preparation for use and repackaging forshipment. NOTE FPS1000 power supplies series generate magnetic field which might affect the operation of other instruments. If your equipment is susceptible to magnetic fields, do not position it adjacent to the FPS1000 unit. 3.2 PREPARATION FOR USE In order to be operational the power supply must be connected

3.7 CONNECTING THE LOAD WARNING Turn off the AC input power before making or changing any rear panel connection. Ensure that all connections are securely tightened before applying power. There is a potential shock hazard when using a power supply with a rated output greater than 40V. 3.7.1 Load Wiring. The following considerations should be made to select wiring for connecting the load to the power supply: * Current carrying capacity of the wire (refer to 3.7.2). *Insulation rating of the wire

FPS1000 Instruction Manual 3.7.3 Noise and Impedance Effects To minimize the noise pickup or radiation, the load wires and remote sense wires should be twisted-pairs of the shortest possible length. Shielding of the sense leads may be necessary in high noise environments. Even if noise is not a concern, the load and remote sense wires should be twisted-pairs to reduce coupling between them, which might impact the stability of power supply. The sense leads should be separated from the power lea

3.7.7 Input/Output connector information The FPS1000 series uses male connector PCIB24W9M400A1, Positronic connector. To mate FPS1000 series to the load circuitry, use female connector PCIB24W9F400A1-S1031, Positronic connector. Refer to Table 3-4 and to the Outline drawing in chapter 2 for the connector pinout description. Pin No Function Description 1,2,4 +V Positive output voltage. Maximum current capacity: 24A/contact. 3,5,6 -V Negative output voltage. Maximum current capacity: 24A/contac

FPS1000 Instruction Manual CHAPTER 4 FUNCTIONS AND FEATURES 4.1 Input Voltage Range Input voltage is single phase 85~265Vac (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. 4.2 Output voltage trimming The output voltage can be adjusted within the specifications via the V_Trim pin at the In/Out connector. Refer to Fig 4-1 typ

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. The open collector output is referenced to the Signals_Return potential and is isolated from the power supply +V and -V terminals The maximum sink current is 10mA and the maximum external voltage is 15V. Refer to Fig 4-3 for typical application. 16 12V aux FPS1000 10KΩ 9 DC_OK 1

FPS1000 Instruction Manual 4.11 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. In case that the sensing wires are long, use separate twisted pair wires for the sensing and for the load wires to minimize noise pick-up. It is recommended to connect electrolytic capacitors in the following locations: 1

FPS1000 Instruction Manual 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. Each load should be separately connected to the remote distribution terminals (see Fig 5-4). If remote sensing is required, the sensing wires should be connected to the distribution terminals or at the most critical load. +V 1,2,4

CHAPTER 6 PARALLEL AND SERIES OPERATION 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. Derate the total output current by 10% when using parallel operation to prevent overload condition. The built-in Oring diodes on the main output and the 12V Auxiliary output allow N+1 operation. For input voltages less than 100V

FPS1000 Instruction Manual 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. By this way, the control and monitoring signals of the paralleled units can be connected to the same control and monitoring circuitry. The Signal Return bus can be connected to the -V or -S or +V or -S or float. Fig 6-3 shows typical connection of the Signal Return at parallel operation. FPS1000 #1 9, 11, 12 AC_FAIL DC_
