The PM15-2 is built with the most advanced high voltage technology available. The combination DC Hipot/high voltage Megohmmeter makes the PM15-2 extremely versatile and thus valuable for field or in-house applications. It incorporates a variable overcorrect trip circuit which will instantly de-energize the high voltage power supply if such a condition is encountered. The trip setting can be as low as 10% or as high as approximately 110% of full scale reading. Overcurrent trip is indicated by an audible alarm. The unit will go into current limiting state at approximately 110% of full current output rating. Designed with the technician in mind, the PM15-2 utilizes the latest in switching power supply technology which produces less ripple (.4% pk-pk at full output) and brings the total weight of the unit down to an incredible 15lbs (6.8 kgs).
