HO 25-P/SP33

HO 25-P/SP33 is a HO-P/SP33 series current transducer for the electronic measurement of current: DC, AC, pulsed, with galvanic separation between the primary and the secondary circuit. Standards include EN 50178: 1997, IEC 61010-1: 2010, IEC 61326-1: 2012, and UL 508: 2018. Applications include AC variable speed drives, static converters for DC motor drives, battery-supplied applications, uninterruptible power supplies (UPS), switched mode power supplies (SMPS), power supplies for welding applications, the solar inverter on the DC side of the inverter (MPPT), combiner box.

• Hall effect measuring principle, low power consumption
