Capacitance

The ESDR0502B is designed to protect voltage sensitivecomponents from damage due to ESD in applications that require ultralow capacitance to preserve signal integrity. Excellent clampingcapability, low leakage and fast response time are combined with anultra low diode capacitance of 0.5 pF to provide best in classprotection from IC damage due to ESD. The small SC−75 package isideal for designs where board space is at a premium. The ESDR0502Bcan be used to protect two uni−directional lines or one bi−directionalline. When used to protect one bi−directional line, the effectivecapacitance is 0.25 pF.

REGATRON Performance. Precision. Quality. 14.04.2023

Page 1/5 TC.ACS.50.528.4WR.HC.LC Programmable Bidirectional AC Power Source Features Scope of Application The increasing number of alternative power sources like solar, wind driven or biological energy systems call for consistent and well demanding regulations for energy feed into the utility grid. Manufacturers of such systems have to test and to prove the compliance of their equipment. REGATRON TC.ACS represents the newest generation of fully programmable, full 4-quadrant grid simulation systems. Modular architecture and additional operation modes make them an ideal choice for test and R+D laboratories. TC.ACS - Programmable Parameters Each phase individually programmable Variation of fundamental frequencies up to 1000 Hz Variation of phase angles Variation of amplitudes Step changes of fundamental frequency Voltage drops either three phase or each single phase Asymmetric three phase voltages Micro-ruptures and flicker Periodic and single shot under- and over-voltages Superimposed harmonic and inter-harmonic voltages up to 5 kHz Specialized software for EMC characterization The Grid Simulation System as a Building Block of a Complete Test Environment Owing to the full 4-quadrant capability of the TC.ACS system, almost all AC power equipment can be tested with the appropriate test procedures. An integrated test environment for solar inverters is composed of a Solar Array Simulation block (SAS), the device under test (DUT) and the grid simulator system (ACS). While the REGATRON SAS components allow for precise simulation of a user-defined solar array of any order under arbitrary conditions, the ACS simultaneously defines the different test conditions with respect to the grid connection. Depending on the requirements, the ACS functionality may be tailored with various software options. In addition to the Basic Waveform Generator Mode and the Amplifier Mode, which are within the standard scope of delivery, the options Full Waveform Generator Mode with Fourier Synthesis Tool, Current controlled Amplifier Mode and Load Simulation Mode are available. Software An intuitive application based software with various options allows for manual operation, programming and for automated test runs. With the optional Full Waveform Generator Mode (GridSim) a set of predefined voltage shapes – sine, cut sine, square, triangle, sawtooth, user defined - facilitates a quick and easy definition of specific grid situations. This software option also offers freely programmable modulations on each phase for amplitude, frequency and phase angle. Hardware REGATRON grid simulator systems use a state of the art multilevel double inverter technology. The main advantages over existing linear power supplies are a substantial reduction of power losses, full 4-quadrant operation, very compact power units and the modular, cost-effective architecture. This allows the user to choose a system size well-fitting his requirements, including the possibility for future power expansions and/or splitting-up of the system into several stand-alone subsystems. The basic triphase power units of 30 kVA or 50 kVA may be expanded by simply paralleling further blocks even to big systems reaching 2000+ kVA. Even higher power levels may be achieved by means of multi-system operation. With the availability of the active neutral string, any single phase or asymmetric condition can be simulated. Additionally, the neutral can be connected to Protective Earth (PE), if required. The system will allow for all relevant testing according to the grid-feed-in regulations (CENELEC, DIN, IEC). Note the operation as a grid simulator, as fast triphase full 4-quadrant voltage amplifier and as a programmable electronic load are possible. Application Example
