AC / DC Sources, Electronic Loads, Invertors, Power Supplies, Bidirectional DC Sources.

  • AC Sources: Electronic AC sources are used to simulate frequency, voltage, wave form, phase angles and current of different single- and three-phase networks. Our single- and three-phase AC sources feature excellent control data and cover a performance range from 250 VA to 150 kVA.

  • DC Power Supplies: Programmable and manually operated DC laboratory power supplies. In addition to analog interfaces, our devices can also be controlled by IEEE, RS-232/485, USB or LAN. We offer you switch-mode as well as linear supplies certainly addressing all requirements with their 120-watt power spectrum.

  • DC Loads: A broad range of voltage, current and power. For operation via computer an IEEE 488.2, RS-232/485, USB or LAN interface can be built in enabling remote control and systems integration. The devices allow constant current and constant resistance operation. The test parameters can be preset and the Dynamic option additionally enables constant voltage and constant power operation.

  • DC-Source / Load with Power recycling: This 2 quadrant DC System is ideal for the evaluation of electrical motors used in modern vehicles. The use of modern control techniques with a PWM rectifier (IGBT) ensures high dynamics over the entire power range.
