B&K Precision, a supplier of test and measurement equipment, has released a modular programmable DC electronic load system for testing a variety of DC power sources, including multi-output AC/DC power supplies, batteries, fuel cells, and photovoltaic arrays. The MDL series is “comprised of six modules ranging in power from 200 W to 600 W” that can be installed in varying combinations in the MDL series 4-slot mainframe for “multi-channel operation”; a mainframe extension is also available.
According to the company, “all DC load modules in the MDL Series can operate in constant current (CC), constant voltage (CV), constant resistance (CR), constant power (CW), and constant impedance (CZ) mode, which uses DSP technology to simulate realistic non-linear loading behavior. Depending on the module, users can select from operating voltage and current ranges up to 500 V and 120 A. A 250 W dual-channel module supporting flexible power allocation up to 300 W is also offered. Load modules in the MDL Series mainframe can be synchronized and connected in parallel for increased current and power.”
The MDL series also provides “all necessary protection functions for various testing conditions,” including overvoltage, overcurrent, overpower, overtemperature and local and remote reverse voltage protection testing.
