DC-DC Converter

Product Details

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).

Operational Features

• High efficiency, 94% at full rated load current
• Delivers up to 55A of output current (660W)
• Input voltage range: 44-52V
• 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
• Industry standard size: 2.390" x 2.490" x 0.512" (60.6 x 63.1 x 13.0mm)
• Height only 0.50” (12.7mm)
• Weight: 4.3oz (123g)

Control Features

• On/Off control referenced to input side (positive and negative logic options are available)

Safety Features

• 2250V, 30MΩ input-to-output isolation
• UL 60950-1:2003 Basic Insulation
• CAN/CSA-C22.2 No. 60950-1:2003
• EN60950-1:2001
• RoHS compliant (see last page)

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
