The MegaPulse 1.2×50/8×20-2.5PF 12Ω is our 2.5kV, 12Ω combination tester, with a 30 second cycle time. It can produce a combination test waveform at 12Ω 2.5kV, in tolerance with EN 60060.

Features grounded outputs, and is acceptable for unpowered testing.  Not for powered testing with a CDN.

The MegaPulse 1.2×50/8×20-2.5PF 12 ohm is equipped with a relay allowing switch selected polarity output. With the switch selected polarity output, users may opt for computer control via our TestMinder option or PLC guided operation with our Relay Isolated Interface option.

The tester charges in less than 30 seconds. Sold with a one year warranty and calibrated to NIST Standards. ISO17025 Calibration available at extra charge.
