MML-4 Elgar Mainframe

The Ametek / Elgar / Sorensen MML Series Modular Medium Programmable DC Electronic Loads are ideal for test environments requiring a variety of medium power loads. This series has single input loads from 100W to 600W. Two mainframe sizes, both 4U (7”) high, accommodate either benchtop (10.8”) wide or full rackmount environments.

This DC load series is ideal for engineering or manufacturing test applications. The loads have been designed to test AC to DC converters, DC to DC converters, power storage devices and electronic components. The system is easily configured by using front panel plug-in modules. The system can be operated by front panel keypad control, standard RS 232 or optional IEEE-488.2 control interface.

The MML Series, 80V modules are available in three power levels, 100 watts x 2 (dual input), 300 watts and 600 watts, all at 80 volts maximum. The 500V modules are available in two power levels, 300W and 600W at 500V maximum. This series can be operated in constant current, constant voltage and constant resistance modes. Each load is isolated and floating, programmable in two current ranges and capable of being synchronized with other load modules in the same mainframe. Each load can simulate a wide dynamic range of loading conditions, including short circuit simulations. Load test sequences can be programmed with different slew rates, load levels, durations and modes. In addition, 10 programs can be stored with up to 10 sequences per program and can be recalled for automated sequencing. Real time measurement of voltage and current with 15-bit resolution is built into each module. Protection includes overpower, overcurrent, overvoltage, overtemperature and reverse polarity to ensure safety and reliability.
