The Sorensen MML-80-60-301 is a 300 W electronic load module engineered for integration into MML Series mainframes. This plug-in module delivers programmable dynamic loading up to 20 kHz, supporting constant current (CC), constant resistance (CR), and constant voltage (CV) operating modes. It handles loads from 80 V maximum and 60 A maximum, with operation down to 1 V for maximum current delivery. The module includes full protection against overpower, overcurrent, overvoltage, overtemperature, and reverse polarity faults, plus photocoupler isolation for true floating load operation.
