Isolation
The PQ60050HZx60 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 both a wide input
range and a tightly regulated output. This module
supplies an isolated step down voltage from 35-75V
to 5V and provides more available power and higher
efficiency than most competitive bus converters. This
converter is available in openframe and baseplated
versions. RoHS Compliant (see last page).
Protection Features
• Input under-voltage lockout disables converter at low Vin 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
• Auto-recovery output over-voltage protection protects load from
damaging voltages
• Thermal shutdown protects converter from abnormal conditions

Note 1: Line and load regulation is limited by duty cycle quantization and does not indicate a shift in the internal voltage reference.
Note 2: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail: support@synqor.com)
Note 3: If the output voltage falls below the Output DC Current Limit Shutdown Voltage for more than 50ms, then the unit will enter into hiccup mode,
with a 500ms off-time.
Note 4: Higher values of isolation capacitance can be added external to the module.
Note 5: Additional 25ms between enable and start of Turn-On time for N logic full-featured units to set up communication.
