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.
