Damage and malfunctions in companies due to poor quality of the power

The NOS (Dutch News Network) reports this week about damage and malfunctions in companies due to poor quality of the power. Inverters, LED lights and variable speed drives are causing more and more interference and this modern technology is itself more sensitive to pollution of the mains. Think of harmonics or distortion of the voltage and current forms, a bad (...)

Starter interface makes testing of intelligent battery and battery chargers easier

The successful PLI series, programmable electronic loads, from H&H is now also suitable for testing intelligent chargers. This by adding the optional Starter Interface (PLI16). Most intelligent battery chargers do not start the charging process until a suitable battery voltage or output voltage is detected. With the optional starter interface, the PLI series can be used to start a discharge cycle by (...)

Programmable DC power supplies for TU/e research water heater of 100 kW: Use of Magna-Power MT and TS series

Researchers at Eindhoven University of Technology use a nine-metre long ‘cooking tube’ to study the behaviour of the combination of steam and hot water flowing together through a pipe. The system is designed for water-steam flows with a pressure up to 40 bar and a temperature up to 250 degrees Celsius. By varying the pressure and water temperature, it is (...)

An 800kVA Grid Emulator/Battery Emulator

Impressive. That was the first thing that occurred to TTMS consultant André Handgraaf. An acceptance test of an 800kVA Grid Emulator / Battery emulator. Emulation of an 800kVA AC grid with freely programmable harmonic (up to the 50th) but also voltage dips, imbalance in the three phases and other grid pollution. The same installation can also be switched to a (...)

TTMS and Isotech give a temperature calibration training

In the month of October 2019, TT&MS BV, in cooperation with its supplier ISOTECH, has provided a successful temperature calibration training for a number of maintenance and calibration engineers of one of its clients. Measuring temperature is one of the most frequently measured quantities. Especially in aviation, measuring and monitoring a correct temperature contributes to reliability and safety. The Engine (...)

192 channel datalogger

192 CHANNEL DATALOGGER TTMS delivered a 192 channel datalogger system to one of its customers. The system is intended to measure the voltage and current distribution in a large production machine for the semiconductor industry. The system consists of 12 PCI cards with 16 input channels each, built in an industrial PC. In the PC we placed a 30TB HD system and (...)

The Cinergia GE/EL+ version AC/DC/VPA

You know from us the Cinergia regenerative Grid emulators, the AC loads, the DC power supply, the DC load, the battery emulator and the Power Amplifier. All versatile instruments that allow us to test extensively to certain standards and save quite a bit on energy costs due to the regenerative power of these units. What is new is that you (...)

The ACL series AC Loads from H&H

Höcherl & Hackl introduces the new electronic three-phase AC load: the ACL series. With the ACL series, H&H makes it possible to load three phases of an AC three-phase system with only one device. This allows compact test systems to be implemented without complex wiring of the control electronics. The three load phases can also be connected in parallel to (...)

New models in the MagnaPower TS series

The Magna-Power TS series DC power supplies consist of 250 different models with power ratings from 5.0 kW to 100.0 kW. Available with an output voltage of 0-5 VDC to 0-6000 VDC and an output current of 0-2,700 Ampere. This series is now extended by another 98 models. The new models have power ratings of 5kW, 10kW, 20kW, 25kW, 30kW, (...)
