The AEL-5000 series includes 20 models of AC / DC electronic loads classified by power range. The power range of a single unit is from 1875 W to 22500 W, and up to 8 units can be connected in parallel. The maximum power of the single-phase parallel connection can reach 180kW and the total power of the three-phase can reach 540kW, features especially suitable for UPS testing applications, inverters / switches , AC and DC power supplies , batteries , fuses but also for other various uses.
The AEL-5000 series has built-in precision measurement circuitry such as 16-bit A/D and DSP to provide accurate measurement items, which include voltage (Vrms) , current (Arms), power (Watts), volt-ampere (VA), crest factor (CF), power factor (PF), total harmonic distortion (THD), voltage total harmonic distortion (VTHD), current total harmonic distortion (ITHD), peak current ( Ipeak), maximum current (Amax), minimum current (Amin), maximum voltage (Vmax), minimum voltage (Vmin), time measurement. In addition, built-in test modes provide UPS efficiency, PV inverter efficiency, UPS backup time, battery discharge time, UPS transfer time, fuse/switch trip/no trip, short circuit simulation, OCP, OPP and other test modes .
The AEL-5000 series offers Turbo mode (ON or OFF selectable), which allows the current and power of the electronic load to be increased 2 times in one second. For test applications that require high transient power and large current such as transient overload testing of protective components or short circuit of fuses/switches and AC supply, OCP and OPP testing, etc. , Turbo mode is the most economical solution.
The entire AEL-5000 series provides overvoltage warnings, overcurrent protection, overvoltage and overtemperature protection. The analog input terminal can control constant current, constant power and other operating modes via external voltage. The Vmonitor / Imonitor terminal is used to connect an external voltage/current monitoring device. In addition, a variety of optional control interfaces such as GPIB, RS-232, USB and LAN are provided to meet all system integration needs.
