Unipolar and Bipolar power supplies from Höcherl & Hackl

With the new NL series from Höcherl & Hackl TTMS did expand their range of four quadrant power supplies with an additional 50 units. The NL models are designed for practical use within laboratories as well as in the fields of production and quality assurance. Each linearly regulated Source-Sink is a voltage/current source as well as a current sink in a single device. The various types cover a voltage range of up to ±50V (bipolar) and up to 100V (unipolar), at currents of up to 320A. Power ratings ranging from 100W to 3.520W are available. If possible, we produce units with higher power ratings upon request.

The unipolar version of the Source-Sink features a restricted four-quadrant operating mode and allows a negative output voltage of up to -1V. This technical facility makes it possible to compensate voltage drops across the device's supply lines. The required voltage/current values as well as the limit values can be entered and set via the digital user interface, the digital communication interfaces or the analog interface. The devices feature RS232, USB as well as a practical analog interface as standard.

Battery test software and software for making a dynamic sequence are available free of charge. The devices in the NL range stand out with their excellent dynamic characteristics and rapid quadrant switching. The units can be used as a four quadrant amplifier as well. With their robust mechanical housings, the devices are designed for industrial 19" rack installation or for use as bench-top units.  
Applications include testing of batteries and accumulators, testing electrical drive systems and testing solar cells and panels.
