Isolation
The PQ60240HZx25 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 24V and is available in openframe and
encased 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
environmental 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.
