Overview

The OWON OEL85 Series DC Electronic Load provides four static operating modes: constant current (CC), constant voltage (CV), constant resistance (CR), and constant power (CP). It supports dynamic loading with T1/T2 timing from 0.1ms to 50s and adjustable rise/fall slopes up to 2000A/ms. The series supports short-circuit simulation and can be expanded through RS485 by connecting multiple units in parallel, except in CV mode. Up to 10 units can be combined for a total system power of up to 4kW. Optional functions include battery discharge testing, over-current protection testing, and over-power protection testing.
