The PEL-023 with RS232 module is a single-channel programmable electronic load manufactured by GW INSTEK. It has a power rating of 30V/20A, a RS232 port for remote control and data logging, and a volumetric bias generator. The RS232 module provides an easy way to communicate with the electronic load via serial port. It features current, voltage, power, and resistance modes. It also has built-in protection features, such as over-current protection, over-voltage protection, short-circuit protection, open-circuit protection, and over-temperature protection. It is suitable for applications such as power loading, burn-in test, dynamic curve, power cycling, aging analysis, and electronic product development.
