New regenerative electronic load from H&H

Höcherl & Hackl GmbH, supplier of high-quality electronic loads, has expanded its product line with the TRL series, a 1,000W regenerative electronic load. The TRL series is characterised by three quiet, relatively small, DC loads. Partly because of this, they are excellent for use in a development/laboratory environment. They don’t require fixed installation, but can be simply plugged into the (...)

The Itech IT-M3900C bidirectional DC power system

The Itech IT-M3900C is a regenerative and compact DC power supply and yet another innovation in terms of versatility and precision. This line nicely complements Itech’s already existing bidirectional DC range and covers the range from 2kW to 12kW. This in very compact enclosures of only 1U height at 6kW and 2U height at 12kW. A wide range of voltage (...)

The Elettrotest TPS/M/D series

The Elettrotest TPS series of single-phase AC power supplies has recently been extended with four new models in the power range from 1500VA to 9000VA. The TPS-D units have a completely redesigned user interface compared to the older models. The unit has a nice 7″ colour touchscreen display combined with a rotary knob to easily make all settings and read (...)

High current AC power sources, Zenone’s GI series

Zenone power generators of the GI series are AC power sources. The series consists of models ranging from 500VA to 50kA/1000kVA for continuous or pulsed operation. Zenone AC power sources are available in single phase and three phase versions. GI series power generators deliver a very stable alternating current at a variable frequency of 40 to 200 Hz. Up to three (...)

Protection Units

Protection Unit (IT-E165A & IT-E118) Before starting a battery test cycle (e.g. charge – discharge) it is important to ensure that the DUT is connected correctly and that the voltage of the source and the DUT match. This is to prevent high currents to the output capacitors in the bi-directional DC power supplies. Itech, supplier of an impressive range of (...)

The new QL bipolar four-quadrant power supplies from H&H

TT&MS BV has expanded its power division with the latest QL series from H&H. This QL series is a completely new line of bipolar power supplies with new functionality, which can function in 2 or 4 quadrants depending on the model. The bipolar power supplies of the QL series have a “SOURCE” and “SINK” mode, which means that the device (...)

The Electronic Single Cell Load

H&H, manufacturer of an impressive line of electronic loads and four quadrant power supplies, has developed the new SCL series especially for testing high-current DUTs such as fuel cells and battery cells. This electronic Single Cell load can load a connected voltage source up to 1,200 A at a minimum input voltage of only 600 mV (standard models) or even (...)

How battery tests ensure safety

The increasing popularity of electric vehicles has led to an increase in the need for batteries. Often, these battery cells and/or batteries are imported from Asia and it is mainly about price and not about safety. This has to change, because it can lead to dangerous situations, says T&M Consultant André Handgraaf of TT&MS. More attention from the industry would be (...)

How to anticipate network distortion?

Netvervuiling is een begrip dat steeds vaker voorkomt, maar waar niet altijd voldoende aandacht voor is. Er is zeker sprake van meer bewustwording, maar toch staat dit onderwerp niet erg hoog op de agenda van veel bedrijven. Dat is op zich begrijpelijk, want netvervuiling is een lastig te definiëren begrip, stelt consultant René Bos van TT&MS. Het is namelijk niet direct (...)
