Product Details

The PQ60280HZx22 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 28V and is available in openframe and encased versions. RoHS Compliant (see last page).

Operational Features

• High efficiency, 94% at full rated load current
• Delivers up to 21.5A of output current (602W) with optional base-plate configuration
• Input voltage range: 35-75V
• Fixed frequency switching provides predictable EMI performance
• No minimum load requirement means no preload resistors required
• Wide output voltage trim range (-50%, +10%), see trim section

Mechanical Features

• Industry standard half-brick pin-out configuration
• Size: 2.30" x 2.40" x 0.428", 58.4 x 61.0 x 10.9 mm
• Total weight: 2.6 oz. (75 g)

Control Features

• On/Off control referenced to input side (positive and negative logic options are available)
• Remote sense for the output voltage

Safety Features

• UL 60950-1/R2011-12
• EN60950-1/A2:2013
• CAN/CSA-C22.2 No. 60950-1/A1:2011

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
