The VAR 3005 dual-voltage supply source from Teseq offers two power sources in one unit. Controlled by the company's NSG 3000 test generators, the supply source regulates test voltage and generates the reduced variable voltage for dips and drops of equipment under test (EUT). The VAR 3005 features internal microprocessor-based electronics, self-regulation, and self-test features including power volt and phase rotation check. The unit generates dips, drops, and variation tests for equipment with a current rating below 16 A. EUT supply input voltage range is from 10 to 240 V ac. Based on plug-and-play technology, the VAR 3005 auto-configures tests to prevent errors, can inform users if conditions are not correct, and can turn off the EUT during a power overload. A single source model also is available.
