The EL series of electronic DC loads

This series of programmable high power density electronic DC loads offers three voltage ranges 200V/600V/1200V. Supports 4 basic operating modes CV, CC, CR and CP as well as 3 complex operating modes CV+CC, CV+CR, CR+CC. Full protection including OCP, OPP, OTP, overvoltage 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 power and automated testing. Built-in RS232, RS485 and USB communication interfaces, LAN&GPIB communication card is optional. Two or more loads can be connected in master-slave parallel mode to provide more power or current capacity. This series DC load can be used for battery discharge, DC charging station and power electronics and other electronic products.
