Switch-off and discharge unit
When testing power electronics with high DC values it is necessary to make sure that the test circuit and the DUT are de-energized at the end of the test. For this purpose, Löhnert Elektronik developed a switch-off and discharge unit which ensures the safe switching off and monitoring of DC circuits with 15 V DC up to max. 750 V DC and max. 60 A DC.
- Safe switch-off and discharge of DC circuits
Voltage range from 15 V DC up to max. 750 V DC
Current range from 1 A to 60 A
Application: Switch-off and short-circuiting unit for DC link test

Automation Controller
The Automation Controller „AuCo“ is a central control unit with several pre-installed digital interfaces and communication devices for minor automation applications.
The interfaces are:
- Digital interface for safety control
RWM driver for DC motors
Digital and analog interfaces to multiple devices
Digital inputs and outputs for automation devices
Ethernet interface for connecting a computer via REST-API
CAN interface for basic CAN communications
Serial interface for diagnostic purposes
A typical application can be the control of a marking laser with parts’ handling.
Advantages
The compact design offers connecting with the individual actors via direct cable connections so that constructing an electrical cabinet is not necessary. Being individually programmable, the AuCo provides multiple and fast control and communication functions.
Software interfaces
The AuCo is programmed in C as embedded system. The basic functions of all interfaces and automation functions as well as communication functions are pre-installed. Therefore the software design must only be realized in a periodic form, similar to PLC programming.
However, the AuCo can also be used in combination with a PC application like LisRT V3 where the requested functions are programmed in Python. Then the Automation-Controller serves as peripheral component for inputs and outputs. For more information please visit www.LisRT.de

Automotive Run-In Controller
The Run-In controller from Löhnert Elektronik is designed to test electronic control units (ECUs) under simulated environmental conditions and has been developed specifically for the automotive sector. The Run-In test identifies ECUs that are faulty due to being subject to high temperatures and load fluctuations over a prolonged period of time.
- Interface connection and monitoring of electronic modules
UUT (unit under test) communication via CAN
up to 3 UUT's simultaneously
Main application: Stress endurance run of automotive control units (ECUs)
