MEWOI-ZC73 Series Programmable Voltage/Insulation Resistance Tester


Brief introduction

The ZC73 series AC and DC withstand voltage/insulation resistance tester is a newly designed 500VA high-power with a maximum output of 5kV/100mA, which meets the requirements of high-power withstand voltage testing and meets the equipment safety standards of EN50191. Based on the basic AC, DC, and insulation resistance tests, the ZC73 series adds a breakdown voltage test function, which can analyze the breakdown point voltage of the product; it also has an open and short circuit detection function, which solves the user’s reliability when testing safety products. For issues of performance and accuracy, contact inspections are performed synchronously during output to avoid missed inspections and improve test reliability and efficiency. At the same time, the floating output design, electric shock protection function, etc., will not be injured by electric shock even when the high voltage test terminal is accidentally touched, which protects the safety of the operator and has no worries during operation.
