Be Prepared for Low-Level Signal Testing
The LLX1 is the ideal solution for testing protection and measurement devices with inputs for low-power instrument transformers (LPITs). A wide range of cables is available that easily connect the LLX1 to devices with specific connectors and pinouts. In addition to simulating phase voltages and currents, the LLX1 can simulate residual voltages and currents for dedicated inputs.
The LLX2 provides a standard low-level interface for controlling external amplifiers, such as the CMS 356 and other low-level accessories, via a 16-pin LEMO-type connector.
The LLX3 expands your test set with low-level outputs that use standard 4 mm sockets, making it a flexible solution for an even broader range of applications, including experimental setups.
