Teseq +DS Option

Three switch solution for positive, negative, auxiliary and short-circuit (LV 124) operation

Besides dropouts like in standards like ISO 16750-2, it is often required by many manufacturers’ standards to perform very fast dropout testing using a switch. This dropout switch in the NSG 5500 +ARB +DS has been totally reengineered from the ground up for clean, symmetrical switching on all three switches: BAT+, BAT- and a new short-circuit (S2) switch for European requirements like LV 124.

Teseq ARB 5500 Arbitrary Generator

Fits in a NSG 5500 for nearly all requirements in one 19” rack

The arbitrary generator ARB 5500 fits in the controller of the NSG 5500 and, together with AutoStar™ 7, provides the necessary control for battery and all battery simulation events, as well as advanced functions like power magnetics and continuous wave (ripple) simulations. This means that with the addition of some transient modules and a dropout switch, nearly all every-day requirements can fi t in one 19” generator.
