H&H PMLA series Multi-channel DC loads
The new H&H PMLA electronic load is a configurable multi-channel load up to twelve channels. The load has up to three cooling units, each with four mounting slots for load modules.

The modules are available in four power classes and four voltage ranges. The voltage ranges are 40 V, 60 V, 120 V and 240 V. The load currents range from 1 A up to 120 A. Depending on power, a module occupies one (150 W), two (300 W), three (450 W) or four slots (600 W).

Configurable
Various loads can be configured, for example 1 x 600 V + 1 x 450 W + 2 x 300 W + 5 x 150 W. The total power is max. 1800 W. The loads can be configured easily to test your multiple output applications.

Applications
The H&H PMLA multi-channel load can be used for calibration of driver outputs, consumer test of electrical systems and testing of batteries and accumulators. It can also be used for testing of cables, absorbers, DC/DC converters, electronic assemblies, electronic fuses and cut-off, fuse boxes, ECUs, power distributors and sensors.

The load inputs are galvanically isolated from each other. For requirements with multi-channel Burn-In equipment it is simple to configure a tailored system based on the PMLA.

Operation modes and functions
Various operation modes are possible: constant current, constant voltage, constant power and constant resistance mode. Adjustable current or voltage protection as well as voltage and current measurement functions are available. A dynamic mode is also possible, allowing up to 100 setpoints. The data acquisition function records up to 100 measurement points (time, voltage, current) at each channel and saves it internally. LabVIEW drivers are available.

Interfacing and remote operation
Extensive data interfaces are available. Ethernet, USB and RS-232 are standard. Analog I/O, CAN and GPIB are optional. Programming is done in SCPI syntax which also offers measurement functions. All channels can be individually addressed.

WHAT OUR CUSTOMERS SAY

ABB

"The ABB Power Grids Jumet organisation is an innovative development and production facility of ABB that manufactures active filters and battery energy storage systems to support a stable grid. To test these systems we have acquired two Cinergia GE/EL +120kVA eplus units capable of doing grid emulation (AC + DC), operating as an electronic load (AC +DC) and being a battery emulator. We have experienced very good support from TTMS in obtaining these two Cinergia units. This included organising an on-site demonstration and supplying loan systems prior to the delivery of our final systems. This way we could start testing as early as possible. TTMS also organised training for the operators from the original manufacturer. This support allowed us to introduce the first battery energy storage systems even prior to the full delivery of the Cinergia systems."

University of Luxembourg

“At the Energy and Environment department of the Faculty of Science, Technology and Medicine (FSTM) of the University of Luxembourg we do have different research projects related to green energy contributing to the development of eco-cities. As a long-standing partner of our research unit, TT&MS has proven that they are able to answer even the most complex questions in a professional manner. They have shown that they are always up to date with the latest technology and do not spare any effort to look at the application and even the situation on site. The exchange of ideas was always very pleasant and took place quickly. We look forward to further years of fruitful cooperation.”
