CHAPTER 7
I 2 C BUS INTERFACE OPTION
7.1 Introduction
The I 2 C 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 I 2 C bus.
The following data can be monitored for the individual units connected to the I 2 C bus:
1. Status of the unit.
2. Actual output voltage, output current and internal temperature of the unit.
3. Manufacturing related data (model, serial number, manufacturing date etc…).
7.1.1 Addressing (A0, A1, A2).
Three address lines allow up to eight FPS1000 units to be addressed on a single I 2 C bus. The address lines are
internally pulled-up to +5V by resistors. Addressing of a unit is achieved by hard-wiring an address line to the
-Sense to set it to "0" or leaving the address line open to set it to "1".
7.1.2 Serial clock
This line is clocked by the processor which controls the I 2 C bus. It should be connected to +5V (referenced to -Sense)
via a pull-up resistor of 2K Ω . The I 2 C interface is designed to run with a serial clock speed of 100KHz.
7.1.3 Serial dataThis line is a bidirectional data line. It should be connected to +5V
(referenced to -Sense) via a pull-up resistor of 2K Ω .

The I 2 C bus address lines, serial clock and data are
referenced to the -Sense potential. When using series
connection of FPS1000 units, do not connect the I 2 C lines
of the units together.
