The MegaPulse 1.2×50/8×20-7-1 2/12 ohm is our 7kV, 3.5kA combination tester, with a 30 second cycle time. It can produce a combination test waveform at 2 ohms from 500V to 7kV, in tolerance with EN 60060; allowing testing to UL 1449, among others.

The MegaPulse 1.2×50/8×20-7-1 2/12 ohm Surge Tester is specifically designed to perform the Impulse Test on transient overvoltage limiting devices in accordance with UL 1449, Section 34; and EN 61010, Para. 14.9, Table 17 and Table 18; and others requiring a Combination Surge Test in accordance with IEC 61000-4-5, with peak voltages no higher than 7kV. This tester can perform the tests shown in Table 17 (up to 7kV) at either 2 or 12 ohms as shown in Table 18. The output is in accordance with the published waveform from 500-12000V peak (open and short circuit). The tester features ungrounded (floating) outputs, and is therefore suitable for use with a CDN for powered testing.  The tests can be done with a 30 second or longer wait between pulses, well within the Standard requirement of 1 minute or less. A 12 ohm tap is provided for testing Category II devices in accordance with Table 18, in accordance with the Standard. The 12 ohm tap will be in accordance with the tolerances of the voltage waveform only, as allowed by the Standard.

The MegaPulse 1.2×50/8×20-7 2/12 ohm is equipped with a relay allowing switch selected polarity output. Users may opt for computer control via our option TestMinder MegaPulse, or PLC guided operation with our Relay Isolated Control board. 

Automated Impedance Switching between 2 and 12 Ω is available.  TestMinder MegaPulse must be ordered as well.

The tester charges in less than 30 seconds. Sold with a one year warranty and calibrated to NIST Standards. A2LA Cal available at extra charge. 

Datasheet, Waveforms and Manual are shown for our 12kV Combination Tester, which is identical to the MegaPulse 1.2×50/8×20-7-1 2/12 ohm, except for physical size and maximum voltage.  Waveforms may be viewed in the Manuals section, below.
