The EL Series DC Electronic DC Loads This series of programmable electronic DC loads with high power density offers three voltage ranges 200V / 600V / 1200V. Supports the 4 basic operating modes CV, CC, CR and CP as well as the 3 complex operating modes CV + CC, CV + CR, CR + CC. Full protection including OCP, OPP, OTP, over-voltage and reverse alarm. Supports external control and monitoring mode, the 0 to 10V input or output signal represents 0 to the full voltage or current range. Provides OCP test, OPP test and short circuit simulation to effectively solve application requirements for performance and automated tests. Built-in RS232, RS485 and USB communication interfaces, LAN & GPIB communication card is optional. Up to 20 loads can be connected in master-slave parallel mode to provide more power (up to 528KW) or current capacity.
