DC/DC Converter
The PQ60120HZA50 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. Targeted for use in intermediate
bus architectures, this module supplies an isolated
step down voltage from 35-75V to 12V and provides
more available power and higher efficiency than most
competitive bus converters. This converter is available
in open-frame and baseplated versions. RoHS Compliant
(see page 13).
Operational Features
• Ultra-high efficiency, 95% at full rated load current, 96.5% at half
rated load current
• Delivers up to 50A of output current (600W) with optional base-plate
configuration
• Wide input voltage range: 35V – 75V, with 100V 100ms input voltage
transient capability
• Fixed frequency switching provides predictable EMI performance
• No minimum load requirement means no preload resistors required
• Wide output voltage trim range (-50% to +5%), see trim section
Mechanical Features
• Industry standard half-brick pin-out configuration
• Industry standard size: 2.3” x 2.4” (58.4 x 61.0mm)
• Total height only 0.50” (12.7mm) for baseplated unit, open-frame
only 0.420” (10.67mm)
• Total weight: 4.3 oz (123 g) for baseplated unit, the open-frame
units are 2.6 oz (75 g)
• Open frame units have flanged pins designed to permit surface
mount soldering (avoid wave solder) using FPiP technique
Safety Features
• 2250 V input-to-output isolation
• UL 60950-1:2003, basic insulation
• CAN/CSA-C22.2 No. 60950-1:2003
• EN60950-1:2001
• RoHS compliant (see page 13)
PQ60120HZA50
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 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)
