7 200 kw 4Q POWE AMPLIFIE POWE ANALYZE FACILITES The POWE ANALYZE included allows acquiring voltage and current signals simultaneously at a maximum sampling rate of 100 kech/s, performing calculations and returning the results of the calculations or samples to a host system. Each channel has its own memory and its own 16-bit converter, allowing sampling on both channels simultaneously. It offers synchronous analytics with the process and enables a significant reduction in the cycle time while improving the accuracy of the measurements. Three modes of acquisition are available : Permanent mode, Synchronous mode, Acquisition-compression mode. ANALOG INPUTS Analog inputs Number of channels 2 Input type Direct Acquisitions Input voltage ±10,0 V peak Common mode max. voltage 15 V esolution 16 bits Accuracy 0,05% of range + 0,05% of measurement Sampling Frequency from 20 Ech/s to 100 kech/s per channel Memory per channel 256 kwords of 16 bits (512 kbyte) Analysis Wattmeter See note (1) Chronometer esolution 10 or 100 µs Accuracy 10 or 100 µs % (1) Each channel can be attached to an electrical signal, currently voltage and current. All of the following operations can be performed on each channel: Mean value MS value during a time of 5 ms to 2 s Variable frequency filter Minimum / maximum imum MS value Measurement time: time during which the signal is greater (in absolute value) to a specified value More details are described in technical sheet FT-Carte ACQ-EN-V1. 7 / 7

8 200 kw 4Q POWE AMPLIFIE THE THEE MODES OF ACQUISITION Permanent mode: signals are continuously analyzed and measurement records are updated periodically. They are accessible by the host system and provide information on the current value of the channel. The time base for the calculation (FFT) is fixed or issued out of the analyzed signal. In the latter case, a high-speed PLL (over one period) calculates the sampling frequency to acquire 1024 points per period. After acquisition, the board makes a FFT without windowing (or rectangular) guaranteeing a high accuracy of measurement with only one period. Synchronous mode: measurements are engaged / disengaged on order of the host system with an accuracy of 100 µs. ecords are updated only during this time period, so that the measured parameters are correlated with stimulus driven also by the host system. As for the previous mode, the time base is fixed or dynamic. Acquisition-compression mode: this mode is possible only on the 2-way cards. Sampling is at the maximum frequency, but only the points that differ more from x % (x being programmable) of the previous point are preserved and dated. It is thus possible to have a maximum of details during a sudden change and a minimum of memory used if the signal is "flat". This mode is particularly suitable for the measurement on a DC bus (batteries for example). CONTOL SOFTWAE Puissance+ OPS3 software allows configuring for each card measurements to be carried out (for example card installed in an AC load system). By activating the continuous repatriation of measurements, this "Power meter" screen is refreshed periodically. It displays the instantaneous values of measures. The rank of the harmonic can be also selected. This Acquisition screen configures the duration of a sample and the duration of the acquisition. It allows also saving the acquisition and launching software visualization OPS1. 8 / 8

Y-coordinates express the current. Continuous operation is allowed inside diagrams. In generation or absorption limitations are due to the heating of the power transistors. Operation 'on the outside' diagrams will result in: an immediate switch-off by over-current protection if current is above the max peak current of the range, a break after a delay by thermal protection in case of overheating of the power parts. ange 300V / 740A (on channel 3) Quadrant Q1: source mode Current is 760 A between 240 and 300 VDC Quadrant Q4: sink mode Current is -480 A between 240 and 300 VDC (60% of source current) In sink mode, limitation is made by resistor in series with power transistors ange 350V / 640A (on channel 3) Quadrant Q1: source mode Current is 640 A between 280 and 350 VDC Quadrant Q4: sink mode Current is -400 A between 260 and 350 VDC (60% of source current) In sink mode, limitation is made by resistor in series with power transistors 12 / 12
