NL Series – 4 Quadrant DC Source – Hoecherl & hackl

Power Products

The Source-Sinks of the NL series are fourquadrant power supply units designed for practical use within laboratories as well as in the fields of production and quality assurance. Each linearly regulated Source-Sink is therefore 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. The devices in the NL range stand out with their excellent dynamic characteristics and rapid quadrant switching. The Source-Sinks can also be adapted to suit your requirements at a later date. With their robust mechanical housings, the devices are designed for industrial 19” rack installation or for use as bench-top units.

Operating Modes

The NL source-sinks can operate in constant voltage or constant current mode. In voltage mode there are two current limiters (source current and sink current) which can be adjusted independently of one another. In current mode, an upper and a lower limit voltage can be set.

Source-sink Mode

Depending on the preset output value and the characteristics of the connected test unit, the device automatically decides whether to operate as a source or a sink. Switching from source to sink mode is very rapid.

2-Quadrant /4-Quadrant Mode

Devices for two-quadrant mode can supply or receive current with a positive output voltage. To guarantee the required function in the case of settings close to 0 V and long connection leads, the 2-quadrant devices start to operate from an output voltage of -1 V. The 2-quadrant devices therefore also act as 4-quadrant devices but with limited negative voltage. 4-quadrant devices can set equal absolute values in the positive and negative range.
