General Introduction
1.1 General Introduction
SSL ELECTRONIC LOAD 32 EL series electronic load is a single input programmable DC
electronic load. It provides a convenient way to test DC power supplies and batteries. It offers
constant current mode, constant resistance mode and constant power mode. Program operation and
control by PC is also available. The backlight LCD, numerical keypad and rotary knob make it
much easier to use. It is an essential instrument for designing, testing and manufacturing of many
suitable products.
