MODEL M120DC

DC Hipot Test Instrument

Safe, Fast, Efficient

• Digital Display (optional)
• Fully programmable test parameters
• Performs DC dielectric withstand test up to 5.5 KVDC at 10 milliamperes (5mA standard)
• Performs concurrent ground continuity test
• ARC and OVERCURRENT detection circuits
• Fast HV shutdown within 2 milliseconds
• Fast discharge of Device Under Test (DUT) upon shutdown
• Full compliance with UL, VDE, BSI, IEC, CSA, and other test standards

Production/Quality Assurance Testing

• Fully automatic test cycle
• Detects and indicates the following
  • Test Ready (security ground chassis sensed)
  • Test in Progress
  • Test Passed
  • Test Failed
• Test parameters easily preset via front panel controls including:
  • Voltage ramp
  • Test time
  • Test voltage
  • Overcurrent trip point
  • Switch-selectable ramp and rest time combinations
  • Arc detection circuit
  • Overcurrent detection circuit
  • Solid state HV generation and control system for reliability
  • Switchable “burn” featured permits destructive testing by maintaining output voltage, following failure, to the DUT throughout duration of preset test time
  • Can be interconnected with M25 Ground Continuity Test Instrument or any ROD-L AC Hipot Test Instrument to simplify multiple testing requirements

Continuos Ground Continuity Monitoring

• Monitors Ground Continuity of DUT before and during each Hipot Test
• Senses for 0.5 ohm (standard), at approximately 1.5 VAC
• Loss of safety ground connection during test causes high voltage to shut down with both audible and visual failure indication
• Inhibits application of high voltage if the security chassis ground is not secure

Superior Safety Features

• Shutdown within 2 milliseconds after dielectric breakdown, overcurrent, or ground continuity fault
• Electronically controlled output voltage ramp rate circuit guarantees consistently smooth ramp
• Visual (audible optional) indication of high voltage applied to DUT
• Discharge circuit provides for rapid discharge of DUT following shutdown
• Visual and audible indication of the following:
  • Arc detection
  • Excessive overcurrent flow
  • Ground continuity test failure
