The APS-7000 power supply series consists of linear alternating voltage sources with a frequency that can be varied from 45 Hz to 500 Hz. Each device in this series contains 9 different measurement and test functions (V rms, I rms, F, Ipk, W, VA, PF, Ipk hold, CF) and offers a similar user interface to the AC power meters. These AC sources require 2 height units in a rack.
With this series, designed as a switching power supply, a very large number of different current levels can be generated, from very small currents with very small resolutions. It is optimized for LED production and for standby mode for corresponding consumers, for example. B. the voltage fluctuations of supply networks, as are often found in public networks, the device not only delivers a stable AC output voltage but also masters 5 methods for abnormal conditions for voltage, frequency and phase, 10 different simulation settings for output power, voltage increase and voltage dip, 10 different sequence modes in which parameters can be selected such as a step-like adaptation to a sine wave, 10 program modes in which the AC output voltage shape as well as the upper limit and the exact point of measurement can be programmed for different DUTs. The rise and fall times can be set in ramp mode for different edge steepness of the output voltages. Voltage surges and dips are also programmable and are added to the set AC voltage at predefined times.
The series is particularly suitable for applications that require highly complex output voltage waveforms and transients in order to be able to test their products under abnormal, adverse conditions.
The APS-7100-UNI model has a universal socket and delivers a maximum output voltage of 310 Vrms at 8.4 Arms and an output power of 1000 VA. The output voltage can optionally be increased to 600 Vrms and the frequency to up to 999.9 Hz.
