*The drawing is for reference only. There may be some differences according to different technical specifications

1. Summary

The TM2000 / 2030 is a series of precision excitation current sources with high precision, high resolution regulation, high stability and other characteristics. It can be used as excitation power supply of field generator such as Helmholtz coil and solenoid to generate standard magnetic field. It’s applied for the influence test of materials, devices and instruments or the calibration of magnetic sensors and other applications.

2. Features

• Single or three channel output are optional.

• Current output can produce a magnetic field (±).

• Optimal short-term stability is 20ppm/min.

• Open loop or closed loop two test modes.

• Open loop can set current or magnetic field value output.

• Closed loop can realize feedback measurement with magnetic sensor.

• Support a variety of value setting and adjustment.

• Support cascaded expansion of current or power output.

• Open circuit, overload, and overheating protection.
