  IEC60601-1 is mainly intended for product development where safety considerations must be taken into account early in the design phase of a product, however much of it applies to production line testing to ensure manufacturer are shipping safe products. Vital areas of medical device electrical safety testing include hipot test or dielectric breakdown, leakage current, insulation resistance and ground bond testing.
- Power Conversion

  - Search All Applications Notes
  Power conversion test equipment for design verification and functional testing demands high precision, reliability, and programmability for the user. When selecting test equipment, UUT protection, long term support, overall cost, and space required must also be important factors.
- Safety / Compliance
  - AC DC Hipot Test
  - Insulation Resistance Test
  - Leakage Current Test
  - Ground Continuity, Polarization, and Ground Bond Tests
  Product safety standards contain three primary sets of safety compliance test requirements: (1) constructional specifications related to parts and the methods of assembling, securing, and enclosing the device and its associated components, (2) performance specifications or “type tests” – the actual electrical and mechanical tests to which the test device sample is subjected, and (3) production line tests which are required on all products.
- Solar / PV Inverter

  - Search All Applications Notes
  A photovoltaic or PV inverter, converts the direct current (DC) output of a solar cell or array into an alternating current (AC) that can be fed directly into the electrical grid (Grid Tie), used by a local electrical grid (Off-Grid), or both (Hybrid Inverters). The PV Inverter is a key component in a photovoltaic system, allowing the use of household and commercial AC powered devices.
