55A
Current
The PQ50120HZx50 PowerQor Zeta half-brick converter
is a next-generation, board-mountable, isolated, fixed
switching frequency DC/DC converter. The Zeta series
offers industry leading power density for standard
isolated DC/DC converters with a tightly regulated
output. This 12V module provides 2,250Vdc isolation
and more available power and higher efficiency than
most competitive bus converters. RoHS Compliant
(see last page).

PQ50120HZB55
Protection Features
• Input under-voltage lockout disables converter at low input
voltage conditions
• Output current limit and short circuit protection protects converter and
load from permanent damage and consequent hazardous conditions
• Active back bias limit provides smooth startup with external load
induced pre-bias
• Latching output over-voltage protection protects load from
damaging voltages
• Thermal shutdown protects converter from abnormal
environmental conditions
Control Features
• On/Off control referenced to input side
(positive and negative logic options are available)
