TH1778A: Host Machine (Test Frequency 0Hz-2MHz, Range: 1A/5A/20A)
TH1778AS: Slave Machine (Test Frequency 0Hz-2MHz, Range: 20A)
Friendly interface, easy operation and excellent performance
The instrument adopts a new generation AC/DC superposition
test theory to adapt test requirements for high precision and high
frequency.The built-in embedded MCU with high-performance
can quickly respond to host and slave machine condition or
malfunction and make real time indication, which helps improve
the work efficiency. The new designed friendly graphical
operation interface, included 5 foot control modes and full touch
operation provides convenience and efficiency for users. New file
management system with easy, prompt and accurate operation
can save a group of real-time setting file and 99 groups of userdefined
setting files. It can provide pushed information indication
and cache 2 real-time information. Being provided with two
modes of SCPI instruction systems, it is convenient to set up
production lines or single machine test. Also, it can connects with
any device with serial port and which refer to the SCPI instruction
system design of this machine.
New Trend of AC/DC Superposition Test By virtue of profound
technology and extensive market survey in bias current field,
Tonghui introduced the large power DC bias current source—
TH1778A. CortexM3 ARM CPU with high-performance, graphical
interfaces and full-touch operation make TH1778A series DC Bias
Current Source convenient and efficient for you.
TH1778A series is appropriate for AC/DC superposition test
of magnetic inductors and test occasion for large current. Also,
it can provide magnetizing current for the analysis of magnetic
materials. The adopted new software framework is adapt to realtime
parameter adjustment and operation.
