Teseq variac range VAR 3005 and VAR 3004 comes in a new look and includes great features.
In combination with a PQT module, the VAR series provides the means to feed a preselected, stabilized step-function or variable voltage to a EUT.
The VAR 3005 series will replace the VAR 6501 and VAR 6502 and meets the Teseq
look. We only have one front panel for both versions. The different types are labelled either with VAR 3005-S16 or VAR 3005-D16.
For manual controlled variation voltage we re-boxed the know VAR 6503 and will be
named VAR 3004. The new manual variac has the same box as the previous one, except the colour will match the Teseq look. The NSG 3004 will also be slightly higher in current rate (up to 9.5 A).
Automated single and double variac
The use of variable transformers means that their inherent advantage of a high shortterm overload capability is also conferred on the unit.
- Add-on unit for mains drop-out generators
- One or two motor-driven transformers
- 50 to 60 Hz operation
- 16 A continuous rating for each transformer
- Standard conform shortterm loading up to 80 A
The VAR 3005-S16-type stands for single variac (previously VAR 6501). This variac is
an automated single variac rated for 16 A, 280 V. Once detected, the settings of the
variation voltage Uvar will be possible in Volts or % of mains voltage.
The VAR 3005-D16 D stands for double variac (previously VAR 6502). Both variacs
are automated, each rated for 16 A. Two independent variacs allow to set Uvar as well as the Uin parameter, e.g. to test 110 V EUTs from 230 V mains.
The main advantage and key features of the VAR 3005-D16
Every EUT which needs to be tested for power quality has usually a mains power supply socket with variable input like e.g. from 85 V up to 265 V. So the equipment input needs to vary in this range to fulfil IEC safety and CE recommendation. There is no easy and economical way to test such variable Uin input in combination with the variable drop given from the standard, than with our one box NSG 3005-D16 solution.
The VAR 3005 series is a standard accessory to the NSG 3040 and 3060 family and is required for power quality testing (PQT) dips and drops and is compliant with the latest revision of IEC 61000-4-11 (2004) including the variation test.
The VAR 3005 units are fully automatic controlled, driven from NSG, using the touch
panel interface SUI or the WIN software application. Once detected by the NSG all functions offered by VAR 3005 are available as well as the possibility to switch EUT power on/off.
