DC current source DX series

programmable

The Programmable Current Source (DX series) is a wide-spectrum, high-precision DC steady-current power supply offering fast response, high precision constant current and long-term stable operation for resistive, inductive and capacitive loads. Since the output current of a current source is fixed, it behaves in series with external circuit elements like an ideal current source; it can be converted equivalently with a voltage source in standard circuit transformations.

Key features

• Wide spectrum programmable DC current output with fast response and high stability.
• High precision current setting and low ripple/noise for sensitive measurement and control applications.
• Suitable for resistive, inductive and capacitive loads (electromagnets, coils, LEDs, precision measurement systems).
• Multiple cooling and configuration options across the DX product family (forced-air, water-cooling, true bipolar designs).

Applications

• Magnetism: Helmholtz coils; Maxwell coils; medium electromagnets; high-power solenoids.
• Electrical: True ohm measurement systems; low-resistance precision measurement; multimeter current-range calibration (0.1 level).
• Test systems: Hall test systems; vibrating sample magnetometer (VSM); thin-film magnetic measurement systems; 3D coil magnetic-field systems; rotating magnetic fields.
• Production line detection: Low-resistance online precision measurement; transformer operating temperature detection; precision motor control and detection.
• Semiconductor lighting: High-power LED aging tests; high-voltage LED lamp aging tests.
• Control systems: Precision temperature control; precision electrochemical control.
