Description


MICROTEST 7640 1-Channel 5kV AC / 6kV DC / 100GΩ Hi-Pot Tester

The MICROTEST 7640 is a single-channel, three-in-one electrical safety tester that combines AC withstand voltage, DC withstand voltage, and insulation resistance testing in one production-ready instrument. It delivers up to 5kV AC at 30 mA, 6kV DC at 10 mA, and insulation-resistance measurements from 200 kω to 100 GΩ.

Designed for component, cable, motor, appliance and power-electronics testing, the 7640 combines programmable test sequences with adjustable arc detection, True RMS measurement and a safety interlock. Its colour TFT display, internal file storage, USB host/device connectivity, RS-232, remote control and EXT I/O make it suitable for both engineering benches and integrated production systems.

Key Features
  • Three-in-one AC withstand, DC withstand and insulation-resistance testing
  • AC hipot output from 10V to 5000V, with up to 30mA rated current
  • DC hipot output from 10V to 6000V, with up to 10mA rated current
  • Insulation-resistance testing from 200kΩ to 100GΩ
  • Choice of single-channel 7640 or eight-channel 7641
  • 7641 expandable to as many as 72 channels with compatible 7508A or 7516A scanner boxes
  • Programmable ramp, dwell and fall times from 0.1 to 99.9 seconds
  • Adjustable arc detection with OFF and sensitivity levels 1 to 9
  • True RMS measurement and fixture-leakage compensation
  • Safety interlock protection
  • 4.3-inch, 480 × 272 colour TFT display
  • RS-232, Remote, USB Host, USB Device and EXT I/O interfaces
  • Internal test-program storage and removable USB storage
  • PC connectivity for remote programming, control and test-data logging
Applications
  • Transformers, inductors, capacitors and filters
  • Motors, stators, rotors and coil insulation
  • Wires, cables, insulation materials and high-voltage connectors
  • High-voltage harnesses and multi-terminal assemblies
  • Household appliances and power supplies
  • Automotive power boards and battery flexible PCBs
  • New-energy vehicle electrical assemblies
  • Engineering validation and safety-compliance testing
  • Quality control and automated production-line testing
  • Multi-point and parallel testing with the 7641

Perform AC hi-pot, DC hi-pot and insulation-resistance testing from one platform.

Three safety tests in one

The 7640 provides one test channel, while the 7641 provides eight configurable channels.

Choose the right channel count

Compatible 7508A and 7516A scanner boxes can extend a 7641 system to as many as 72 channels.

Expand when required

Programmable ramp, dwell and fall timing helps protect the DUT from sudden voltage changes.

Controlled voltage profiles

Adjustable arc sensitivity helps identify transient discharge through weak or damaged insulation.
