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.
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).
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 leads.
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 1,2,4 3,5,6 7 Function +V -V On/Off control Description Positive output voltage. Maximum current capacity: 24A/contact. Negative output voltage.
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.
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.
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.
CHAPTER 5 BASIC CONNECTIONS FOR OPERATION 5.1 Connecting single load, Local sensing Local sensing is suitable for applications where load regulation is not critical. Fig 5-1 shows recommended load and sensing connections for applications with a single load.
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.
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.
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.
6.2 Series operation Two 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. Each diode should be rated to at least the power supply rated output voltage and output current. Refer to Fig 6-5 and 6-6 for typical lseries connection of power supplies. Series connection for increased output voltage.
FPS1000 Instruction Manual CHAPTER 7 I2C BUS INTERFACE OPTION 7.1 Introduction The I2C interface option includes facilities to monitor operating parameters of the power supply. The parameters are then transferred to the host PC if demanded, over a standard I2C bus. The following data can be monitored for the individual units connected to the I2C bus: 1. Status of the unit. 2. Actual output voltage, output current and internal temperature of the unit. 3.
7.3 Block diagram of the I2C option Refer to Fig 7-1 for description of the I2C block diagram and for typical application.

Digital status Digital status functions are provided by a PCF8574, 8-bit Register.
FPS1000 Instruction Manual 7.4.3 Analog functions Analog functions are provided by a single PCF8591, 4-channel 8-bit A/D converter. When this device is read by the serial buscontroller it provides an 8-bit word with the following information: Channel 1: Output voltage, channel 2: Output current, channel 3: Internal temperature.
7.5.3 Internal temperature measurement The internal ambient temperature is measured to provide information of the safe operation of the power supply. The internal ambient temperature is usually higher than the power supply air intake temperature due to internal power dissipation. As the power dissipation varies with the load, the internal ambient temperature increases with the load. Refer to Fig 7-2 for typical internal temperature rise above the air intake temperature versus the load. Internal temp.
