At electronica 2018, H&H presented the new ACL three-phase loads, which operate in both DC and AC mode. The ACL load is designed for 3-phase networks. On the one hand, this eliminates the need for extensive cabling of 3 individual devices, and on the other hand, considerable cost savings are achieved compared to 3 single-phase devices.

The device of the new generation impresses with its large, brilliant touch display, which can be configured user-specifically.
The new ACL series is expected to be available in Q3/2019.

Quick info with model overview

Many thanks to all customers, interested parties and sales partners for visiting the H&H exhibition stand! We were able to meet new contacts and familiar faces, receive constructive feedback and experience new challenges.

With production series B, the PLI series has received both a facelift and many functional improvements.

The front panel color has changed to a modern light grey. The menu navigation of the graphical user interface has been revised. Functional improvements can be mentioned, for example:

– improved MPP tracking (option PLI21) with global maximum detection and storage of swept V/I curves
– dynamic discharge during energy storage test

A major hardware feature is the increase of the isolation voltage between negative load input and PE of the galvanically isolated I/O port (PLI06) to 800 V.

A comparison of the PLI Series A with Series B can be found in this table:



The “small” PLA loads now also have Maximum Power Point Tracking capability, even as standard.

An extensive Maximum Power Point Tracking (MPPT) function for testing photovoltaic panels can be activated. In variable sweep periods, the V/I characteristic of the panel is measured and stored. The sweep direction is selectable. The absolute maximum power found is controlled until the function is stopped or a certain minimum voltage is underrun. If the panel voltage is above the minimum voltage again, the load continues the sweep and control process.

To perform this function, firmware revision 2.1 is required for the concerning electronic load. Please contact the H&H support if you want to update your PLA load’s firmware.

H&H visitor delegation with WARR project manager Martin Riedel (2nd from right) and Pod III

As sponsor of the research project Hyperloop of the TU Munich, H&H was invited to the ceremonial unveiling of the new transportation pod (Pod III).

Already in 2013 SpaceX CEO Elon Musk presented his idea “Hyperloop” for high-speed transport by magnetic levitation train in a vacuum tube. The goal of the vision is to shorten travel times by velocities over 1200 km/h. In 2015, the “Hyperloop Pod Competition” began at the company site in California to advance the development of high-speed transport pods and the research of the new technologies. In 2015, the “Hyperloop Pod Competition” began at the company site in California to advance the development of high-speed transport capsules (pods) and the research of associated technologies. At this event, student teams from all over the world compete with their prototypes on a test track of 1 km to crown the best solution. The team of WARR Hyperloop of the TU Munich has already won here twice in succession, most recently in 2017 at a speed of 324 km/h.

According to Musk, a speed of 500 km/h is to be achieved in the tube in July 2018. During the presentation of Pod III, the project participants even spoke of 600 km/h, which they were aiming at.

For this purpose, H&H provides an electronic load PLI6406, with which the battery cells of the pod are tested under constant and dynamic load. We wish the extraordinarily motivated and ambitious team of WARR much success and the necessary bit of luck on their 3rd trip to L.A. to defend their title!


Our Tobias Schnitzbauer passed his apprenticeship as an electronics technician for devices and systems with flying colors and was honored for this with other best examiners from the IHK committee district Straubing and Straubing-Bogen at a ceremony.

In the presence of several guests of honor, Jürgen Wallstabe, Vice President of the Chamber of Industry and Commerce of Lower Bavaria, presented certificates and gifts to the best examiners. With their final results, they were among the absolute top of the more than 1800 graduates of this year’s winter test, and with the grade “very good” they had prepared themselves a crowning conclusion to their training, according to Wallstabe.

We are particularly pleased that Tobias is continuing his career at H&H and will now enrich our team as an excellent skilled worker.

To perform a measurement on a battery module, we had a visit from a technical delegation from hofer powertrain. In the test, the DUT was first warmed up to a defined temperature by means of the heating device brought along and then cooled down by means of the liquid cooling system available at H&H.

Using an electronic load PLI6406, a constant discharge power was applied to the test object until a defined discharge voltage was reached. A thermographic camera recorded the temperature curve.

The picture shows an employee of hofer powertrain adjusting the temperature of the heating device.

H&H supports the Kaiserslautern Racing Team (KaRaT) in the development of its own drive components for electrically powered racing cars.

An electronic load of the PLI6412 type was used to test the technical data of various components, such as the available capacity of individual cells, internal resistance and thermal behaviour under cyclic load.

H&H calibrates your new device free of charge upon delivery and a second time within 2 years!

With the calibration interval of 2 years recommended by H&H, the customer receives a device calibrated for a period of 4 years – which means considerable cost savings.

H&H supports the TU Darmstadt Racing Team (DART Racing) in the development of their own LiPo and LiFePO4 batteries. Since 2006 DART Racing has participated in the international construction competition “Formula Student” and gained numerous awards.

DART Racing has participated in the international construction competition “Formula Student” since 2006 and converted to the construction of electrically powered racing cars in 2011. The electronic load of H&H is used to test the dynamic properties of the battery. A detailed report can be found in the Customer Application 13.
