Description
The Tonghui TH1779 DC Bias Current Source is a flexible constant current source that provides currents from 0-50 A and supports up to 400 A in master/slave mode via eight units connected in parallel. With a wide frequency range from 1 Hz to 2 MHz, precise current stepping and an intuitive graphical user interface in German and English, the TH1779 is ideal for demanding applications in research, development and quality assurance. The robust unit in a 19″ housing offers SCPI remote control capability, multiple control and monitoring modes and seamless integration into existing test systems.Features
- Single constant current output 0-50 A, master or slave mode
- Parallel connection of up to 8 units for a maximum of 400 A
- Master/slave control for modular expandability
- Fine-step current stepping with 0.1 A resolution
- Frequency response 1 Hz-2 MHz
- Two output modes: continuous current and step-by-step scanning
- Graphical user interface in German/English
- Two SCPI command modes and five control modes
- Direct control via TH2836/38/39/40/48 series possible
Applications
- DC characteristic analysis of inductors and reactors
- Saturation behaviour of ferrite and iron cores
- DC characterisation of other magnetic materials
