Associated Research 7550DT HypotULTRA®II Electrical Safety Compliance Analyzer
The Associated Research 7550DT is designed to meet safety agency standards such as UL, CSA, IEC, VDE, TV and the European Norms including the Low Voltage Directive 73/23/EEC.
The first complete multi-function systems HypotULTRA®II combines the three most common dielectric safety tests (AC Hipot, DC Hipot & IR test) required by agencies such as UL, CSA, IEC, VDE, TV, BABT and others into a single 19 rack mount cabinet which takes up less rack space and allows for testing through a single DUT (Device Under Test) connection. All the functions of the instruments can be programmed over a GPIB, RS-232 or printer interface which makes them adaptable to any automated production environment. The Associated Research 7550DT offers the option of a built-in 8 port scanner and an interface to control up to 2 external 8 port scanners. These optional scanner configurations are ideal for multipoint testing of a single item or multiple product testing. The high voltage outputs of either the internal or external scanner can be set as high, low or off. A front panel display shows the status of each scanner output port.
