The AT8612 DC electronic load is controlled by a high-performance ARM microprocessor with Chinese/English menu display, and provides four operating modes — constant current (CC), constant voltage (CV), constant power (CP) and constant resistance (CR) — plus a variety of functions including normal testing, dynamic testing, sequence list, automatic list, battery testing, OCP, OPP and short-circuit testing.
The instrument has a maximum rated input of 300 V/30 A, supports four-wire (4W) remote testing, is equipped with an RS-232 interface with optional RS-485, and comes with ATS861X data acquisition software as standard for convenient editing of sequence and automatic list files. It is suitable for testing linear power supplies, switching power supplies, battery chargers and batteries.
