The MegaPulse Implantable Test 1 outputs the damped sinus pulse used to defib-proof test implantable medical devices.  Resistor networks described in the Standard Tests are included internally.  The MegaPulse Implantable Test 1 can recharge and trigger the next pulse in 20 seconds, in accordance with the Standards.  Positive and negative polarity are selected with a front panel switch, or via optional computer control.  The computer control can conduct the test sequence shown in the Standard.

The tests are described in the following Standards:

  1. EN 45502-1:2015, clause 20.1, Test 1, Figures 1, 2 and 3; 140V peak.
  2. ISO 14117:2012, clause 6.2.2, Test 1; Figures 45 and 46; 380V peak.
  3. ISO14708-1:2014, Part 1; 140V peak.
  4. EN 45502-2-2:2008, clause 20.2; 380V peak.
  5. EN 45502-2-1:2003, 140V peak.
  6. EN 45502-2-2-3:2010, 140V peak.
