AC electronic load with optimal power factor and crest factor for three-phase output product applications.
The 63800 series is suitable for testing power devices such as uninterruptible power supplies (UPS), off-grid inverters, AC power sources, switches, and breakers. Even when the voltage waveform is distorted, the 63800 series can simulate load conditions with high peak factors and varying power factors while performing real-time corrections. This capability allows for real-world simulations, yielding reliable and unbiased test results. Additionally, using DSP technology, it can simulate nonlinear rectifier loads through a unique RLC operating mode. In this mode, it detects the DUT's impedance and dynamically adjusts the control bandwidth of the load to ensure system stability. The comprehensive measurement capabilities of the 63800 series allow for monitoring the output characteristics of the DUT. Furthermore, voltage and current signals can be verified on an oscilloscope via analog output. Standard interfaces such as GPIB and RS-232 are used for remote control and measurement data transfer for system integration. Additionally, the built-in digital output can be used to control external relays for short-circuit (crowbar) testing.
