Overview

The OE4201 is a floating ground-isolated voltage-controlled current source device, which can provide a current source for other instrumentation.The OE4201 outputs AC current with a gain of 2mA/V and 200mA/V in two steps, and a frequency of 1Hz-100kHz. As a current source instrument, the OE4201 has high accuracy, good stability, the output is basically independent of the load and external voltage changes, strong anti-interference ability, and fast response time. It is suitable for use with sensitive AC instruments such as lock-in amplifiers, providing a simple method of generating precision current from AC voltage. Moreover, the OE4201 adopts a standard chassis with a compact, beautiful and reliable internal structure and flexible switching action, which makes the instrument easy to use, adjust and maintain.
