Half-brick
Input
Output Current Isolation 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 tight-
ly 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 con-
verters. This converter is available in open-frame and base-
plated versions. RoHS Compliant (see page 12).
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 grams) for baseplated unit,
open-frame 2.6oz. (75 grams)
• Flanged pins designed to permit surface mount solder-
ing (avoiding wave solder) using FPiP technique
Control Features
• On/Off control referenced to input side (positive and
negative logic options are available)
PQ60120HZA50 Module
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 haz-
ardous 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
Safety Features
• 2250V, 30 MW input-to-output isolation provides
input/output ground separation
• UL/cUL 60950-1 recognized (US & Canada), basic
insulation rating
• TUV certified to EN60950-1
• Meets 72/23/EEC and 93/68/EEC directives which
facilitates CE Marking in user’s end product
• Board and plastic components meet UL94V-0 flammabil-
ity requirements
