With the NSG 603 plug-in unit interruptions and vol-
tage fluctuations on AC and DC mains can be simu-
lated in accordance with generally known standards.
Thanks to the use of state of the art semiconductor
technology, power-MOS-FETs and microprocessor
control, supply dropouts can be inserted at any
desired phase angle. The respective times for repeti-
tion, drop out time and phase displacement can be
programmed by the decimal keyboard and LCD dis-
play on the main frame or via remote control equip-
ment.
For voltage variations a second voltage source (e. ~.
motorized Variac, electronic AC-source, DC supp y
equipment) is connected on the rear side. A control
output 0 + 10 VDC controls the additional source
adjusting the outputs to the desired value, pro-
grammed on the main frame-unit.
Provision has been made on this equipment for the
connection of a future 3-phase extension and an
external switch with high breaking capacity.
The system has automatic overload protection to pre-
vent damage to the NSG 600 from failure in the equip-
ment under test.
