Dynatronix High Current Power Supply

Dynatronix High Current Power Supply

This high current power supply can provide a maximum DC of 100 A with maximum voltage of 12 V. Both ampere and voltage can be changed either manually or automatically system driven.

The resolutions of voltmeter and amp meter are 0.01 V and 0.1 A. It allows ampere time cycle control so that both DC on- and off-times are adjustable for high frequency.

Other features include:

  • real time cycle control
  • ampere time totalizer
  • digital input for inhibit/operator control
  • process storage/data logging
  • USB port for serial control

THDM-III High Current Pulse Supply

This high current pulse supply can provide electrical pulses with a maximum current amplitude of 4000 A, and a maximum power output of 12 kVA. The current amplitude and the pulse frequency can be adjusted. The frequency of the current pulse can be selected from 100 Hz to 800 Hz with a resolution of 1 Hz. The resolutions of the voltmeter and the amp meter are 0.1 V and 0.1 A. The width of the pulses is fixed at 68 μs. It allows a continuous and stable output of high electrical current pulses during the operation. An embedded detection and analysis system allows real-time characterization of the dynamic high current pulse output.
