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. Remote Control Most source-sink functions can be controlled remotely via the standard Analog I/O Interface. Operating mode selection, output on - off and setting of control speed can be set with logic levels. A version (NL06) which is electrically isolated from the output is optionally available. Analog Control Inputs Depending on the selected operating mode the output voltage or output current can be preset by control voltage 0 ... ±5 V or 0 ... ±10 V DC. There are two further analog inputs available to limit the voltage or current. Analog Measurement Outputs For voltage and current there are 0...10 V analog measurement signals available. The signals follow the curve shape.
