The Instek APS-7100E Linear AC Power Source, 1000VA is 2U height, with the output frequency range of the series is 45~500Hz; its maximum rated output is 1000VA, 310Vrms, 8.4Arms. The APS-7100E comprises six measurement and test functions (Vrms, Irms, F, Ipk, W, PF), and has a user interface similar to that of an AC Power Meter. Via switching many sets of current levels to increase small current measurement resolution, this instrument is ideal for the LED industry and standby mode power consumption tests. To meet the test criteria of line voltage fluctuation often seen in consumer electronics, the APS-7100E not only supplies a stable AC source, but also features test mode to handle special purpose or abnormal voltage and frequency. Test mode features ten sets of memory to simulate power outage, voltage increase, and voltage drop. The APS-7100E is ideal for producing grid power transient waveforms to verify electronic product operation, under adverse conditions.
