Brief Description

Setting and display

Three displays are provided for indication of the nominal and actual values. A separate display is provided for status information and menu-guided operation.

Variable by percentage

For module testing, NGPT35 provides the possibility of varying the output voltage of all three channels simultaneously in percent. After selection of the channels to be included in this operating mode, the desired variation can either be set via the numeric keypad or in steps of 0.1, 1 or 10% using the increment/decrement keys.
