1800W modular electronic loads for power tests

November 06, 2014 // By Graham Prophet
Interpro Systems’ ML1800 Series of 1800W modular electronic loads features an 8-in. TFT LCD colour display with multiple language selection that is visible at a distance. The 6-slot chassis is rated at 1800W and can be specified with up to six 300W or three 600W modules.

Modules are available with current ratings of 60 or 120A with voltages up to 80V; or 10 or 20A with voltages up to 500V. The load offers CC, CV, CR, CP, short circuit, battery and LED operating modes, 20 kHz transient test speeds with programmable rise, dwell and fall times, inductive load and capacitive load simulation, for testing of power supplies, batteries, LEDs, adaptors and converters.

16-bit programming and measurement resolution lets the ML1800 be operated as standalone instrument as well as having the capability to be integrated into a larger test system. It offers 10 user-programmable stored test sequences of up to 10 steps each. Programs can be run once, continuously looped or run once and then chained to other programs to provide very complex loading profiles.

Test modes can be changed without turning off the load input. This allows the ML1800 series to more accurately simulate load testing applications. Turn-on capacitance and inductance simulation is easily performed using the CC Rise and CV Rise modes. The load's LED mode and Battery simulation functions allow for quick setup and execution for these power products. The CC to CV and CR to CV functions also provide the user with special loading simulation features.
