The linear technology used for these amplifiers allows: o A high dynamic, a very low distortion on a wide frequency range and a large bandwidth o To provide power peaks up to 4 times its nominal power o An easy integration for Real-Time or Power Hardware In the Loop applications with simulators o A power factor between +1 (source mode) and -1 (sink mode). Entirely self-sufficient with its local control on touch screen, they can be controlled remotely from a supervisor system via an Ethernet or RS232 link for easy integration in a complex test system.

Connection IN PARALLEL of amplifiers outputs is not allowed. Three-phase system: For size and weight reasons, a three-phase amplifier PA-3x3000 is made of three single-phase amplifiers PA-3000 connected in Y. These three amplifiers are associated: one of the three is master, the two others are "slaves". The master amplifier provides to the slaves amplifiers a timing signal in order to control the phase shift, editable, between them. The master amplifier receives measures and status of the slaves amplifiers and ensures the communication with an external supervisor (PC or PLC). Document ref.

PERMANENT OPERATING AREAS IN AC These diagrams express the relationship between the current and the voltage for different values of power factor. X-coordinates express the voltage as a percentage of the range. Y-coordinates express the current percentage of the rated current of the range. Continuous operation is allowed below curves. Limitations are due to the heating of the power transistors. Operation above diagrams will result in: An immediate switch-off by over-current protection if current is above the limits, A break after a delay by thermal protection in case of overheating of the power parts. These features are for each phase. Blue trace: dephasing between voltage and current is null. The power factor PF is equal to 1 (generation on resistive load). Green trace: dephasing between voltage and current is 90 (π / 2). The power factor PF is equal to 0 (generation on inductive load). Red trace: dephasing between voltage and current is 180 (π). The power factor PF is equal to -1 (full absorption). PROTECTIONS Against overload: current limitation Amplifiers in linear technology can generate up to four times their rated power during short time. They are using voltage regulation with current limitation: if current is higher than programmed value, a timer starts. At the end of a programmable time between 0.1 and 5 seconds, output voltage decreases to limit current to the programmed value. Against short-circuit on output: automatic output switch-off Output is switched off on all phases et must be reactivated using touchscreen or an external command. Against overtemperature: automatic output switch-off A temperature sensor is installed on each power part. It switches off outputs of the three phases in case of overheating. After cooling, output must be reactivated using touchscreen or an external command. Against overvoltage and undervoltage amplifier is protected against overvoltage or undervoltage. If this event is very short, hardware protection will limit effects. If this event is too long (> 100 ms), output is switched off to protect power parts. The time-stamping of the events starts as soon as the source is powered. Date and time can be modified locally or remote. Document ref. Amplifiers 4Q AC DC Single-Three phases 3000VA V4 - Page 4 / 11
