Compliance West 1.2x50-12kVP-39 - Waveform up to 12kV, 39Ω MegaPulse Surge Tester

MegaPulse 1.2x50-39P 39 ohm was designed to perform all tests noted in EN 60335, Paragraph 14. The virtual impedance is 39 ohm, in accordance with the Standard, and the tester will charge within 3 seconds in accordance with the fastest repetition rate allowed by the Standard. For automated pulse train testing, use the MegaPulse TestMinder option, which allows automated pulsetrain testing controlled from a PC.

MegaPulse 1.2x50-12P 39 ohm, 400-12.3kV, 3 sec charge time, 39 ohm virtual impedance.  In accordance with the requirements in IEC 1180-1 Section 6.2; and other Standards by reference.  It is acceptable for use with unpowered samples rerquiring a 39 ohm impedance, with no current waveform defined.  It is designed to test IEC 60335, Table 7 in its entirety. This tester is in accordance with the measurement requirements of CTL DSH 251B.

The switch is our IER model.

The meter shows the peak of the output waveform into an open circuit. Impedance of the device being tested will attenuate this peak value.  Pulse delivery one per minute for pulses above 6kV; two per minute for pulses below 6kV.

Please see Manuals Section below to view waveforms.

This tester can be provided with Option 950-12, which allows testing to IEC 60950 Annex N/IEC 62368-1 Annex D; Line 2.

1.2x50 waveform with 12 Ω or 39 Ω output, 400–12kV  

A Compliance West surge Tester. That means it outputs a guaranteed waveform but won't break the bank. The tester outputs the waveform it is supposed to, time after time.

Waveform Measurement Setup

Testing

1. Connect the tester to a proper source of supply using the included 18 AWG power supply cord.Make   sure   that   the   front   panel   VOLTAGE   adjust   knob   is   turned   fully counterclockwise.  
2. Plug the Output and Return test leads into the jacks on the front panel.
3. Connect the ends of the test leads to the equipment under test.
4. Turn the Tester on.  Toggle the POLARITY switch as needed so that the NOR or REV indicator is lit.
5. Note that the Voltage meter may indicate that some residual voltage is present on the main storage capacitor, even when the tester is first turned ON. This is due to inherent charging of the internal capacitors.  Pressing the TRIGGER switch will discharge the capacitors (be sure not to touch the output and return leads when pressing the trigger switch).
6. Push the yellow CHARGE button.  Verify the red TRIGGER indicator is now lit.   
7. Adjust the VOLTAGE knob so that the front panel LED display is reading a voltage that is suitable for the measuring instrument that is being used.  Push the red TRIGGER button, when the desired voltage is displayed on the front panel meter.
8. Note  that  the  peak  amplitude  of  the  measured  output  waveform  is  proportional  to  the voltage that is read of the front panel of the MegaPulse, but it will always be somewhat lower.  This is because the meter on the MegaPulse is measuring the voltage on the main impulse storage capacitor.  This voltage will intentionally dissipate to some extent before reaching the output leads.
