Option AH makes the output of the production line hipot testers HT-2000, HT-2800 and HT-3000 25% higher for just a little bit of extra voltage.

Output voltage can be raised to 2500Vac on the HT-2000 and 3500Vdc on the HT-2800 for special applications. HT-3000 testers with this option can choose between up to 2500Vac or 3500Vdc output.

Current outputs stay as rated for the standard testers and they function exactly as the stock testers, but the voltage output goes to 11.
