TH1778A DC bias current source adopts high-performance microprocessor, which can provide a single 0~20A constant current output, and can be connected to the slave to enhance the maximum output current to 0~120A, with excellent scalability and expandability, and is equipped with a test interface that can be directly connected to the company's various types of L-meters and LCR bridges, which is suitable for AC and DC superimposed testing of magnetic inductors and providing a convenient and practical magnetization current source for the characterization of magnetic materials. The instrument is suitable for AC/DC superposition testing of magnetic inductors and provides a convenient and practical magnetizing current source for magnetic material characterization. The instrument is capable of accepting and responding to real-time current modifications during operation. Adopts the new generation of AC/DC superposition test principle to meet the demand of high precision and high frequency testing. The instrument has a newly designed user-friendly graphical operation interface and provides various control methods: manual key control, footswitch control and remote command control.
