Product Details

The PQ55070HZB52 PowerQor Zeta converter is an isolated, fixed switching frequency DC/DC converter that uses synchronous rectification and a patented topology to achieve extremely high efficiency and power density. This 7.3Vout module provides 2250Vdc isolation and can tolerate output current transients up to 85A. The Zeta series converters offer industry leading useable output power for any standard “halfbrick” module. RoHS Compliant (see last page).
