The PPQ60120HZA50 PPowerQor Zeta hhalf-brick cconverter
is aa next-generation, bboard-mountable, iisolated, ffixed
switching ffrequency DDC/DC cconverter. TThe ZZeta sseries
offers industry leading power density for standard isolated
DC/DC cconverters wwith bboth aa wwide iinput rrange aand aa ttight-
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. TThis cconverter iis aavailable iin oopen-frame aand bbase-
plated vversions. RRoHS CCompliant ((see ppage 112).
Operational Features
• Ultra-high efficiency, 95% at full rated load current,
96.5% at half rated load current
PQ60120HZA50 Module
• Delivers up to 50A of output current (600W) with
optional base-plate configuration
Protection Features
• Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient capability
• 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
• Fixed frequency switching provides predictable EMI
performance
• No minimum load requirement means no preload
resistors required
• Active back bias limit provides smooth startup with
• Wide output voltage trim range (-50% to +5%), see
external load induced pre-bias
trim section
• Latching output over-voltage protection protects load
from damaging voltages
Mechanical Features
• Thermal shutdown protects converter from abnormal
environmental conditions
• Industry standard half-brick pin-out configuration
• Industry standard size: 2.3” x 2.4” (58.4 x 61.0mm)
Safety Features
• Total height only 0.50” (12.7mm) for baseplated unit,
open-frame only 0.420” (10.67mm)
• 2250V, 30 MΩ input-to-output isolation provides
• Total weight: 4.3 oz. (123 grams) for baseplated unit,
open-frame 2.6oz. (75 grams)
input/output ground separation
• UL/cUL 60950-1 recognized (US & Canada), basic
• Flanged pins designed to permit surface mount solder-
insulation rating
ing (avoiding wave solder) using FPiP technique
• 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
Control Features
• On/Off control referenced to input side (positive and
negative logic options are available)
