Measuring instrument category CAT III 300: allows the use of the measuring instrument from tests with safety extra-low voltage (SELV) via 3-phase systems with or without neutral conductor to tests in power electronics, e.g. link voltage of 700 V DC
Digital and media connection

The Machine Test CASSY is fully controllable in real time via the following interfaces:
- RJ45 Ethernet (IP4 / IP6 networks)
- WiFi IEEE 802.11 a/b/g/n supports WPA, WPA2, WPA3 and Radius Server
- USB-C for direct PC connection or for external data carriers, also for simplified configuration.
These interfaces can be used by the following software, among others.
- CASSY Lab 2 for drives and energy systems,
- MATLAB^® and LabVIEW ™ with freely available examples,
- Lab Docs Editor Advanced / Pro for generating individual experiment instructions in HTML and with JavaScript even without programming experience.
The following integrated servers are available in the Power Analyser CASSY for the local media connection of up to 3 end devices simultaneously.
- TCP server for the CASSY app
- DHCP server for use with PC direct connection or as WiFi hotspot
- HTTP server for the CASSY Web App
- WebSocket server for WebSocket clients, such as Leybold Lab Doc
- VNC server for 1:1 transmission of screen contents to remote devices, including a return channel for control purposes.
PLUS:

Isolation amplifiers:
- 4-channel isolation amplifier
- The Power Analyser CASSY Plus outputs the measurement of the instantaneous values of U, I or P of the measuring channels A-D to the ±10 V outputs U-X. The amplification depends on the measuring ranges. Mathematical functions between the channels (A+B, AxB, etc.)
Function generator:
- 1 output channel Y as function generator
- DC / sine / rectangle / triangle and free function
