Release time:2017-02-23 14:25:52 | viewed:

The 4600 series AC electronic load is designed for UPS, inverter and other AC output of power supply products testing. Adjustable crest factor and power factor to make the load can be configured to linear load or nonlinear load to meet the customer's products in different conditions of the test requirements, and is more flexible and reliable than various of resistive load.


         


Ø High precision measurement:

Through the internal circuit, the 4600 series electronic load can realize the high precision measurement of frequency, voltage, peak voltage, current, current peak, peak coefficient, power factor, apparent power, active power, reactive power, peak power, resistance, this kind of measurement capability can avoid the needed external measuring instrument or equipment, reduce cost and improve test speed.


Ø The extensive application fields:

In order to meet the needs of majority of UPS, inverter and other AC output products test, the 4600 series ac load is divided into two sub-series: 3KW series (4600-3) and 6KW series (4600-6), you can parallel many sets of load to meet the needs of more power. Besides, the load can be operated in the CC, CV, CR, CP, SC, UPF, CNL modes.


Ø PC software——empower:

Through the PC software emPower, the 4600 series electronic load can be monitored and controlled, besides, you still can complete real-time waveform display function via this software.
