PQ60260HTB10NNS

Technical Specification PQ60260HTB10 48Vin Input 26Vout Output 250W Power 2000Vdc Isolation Half-brick DC/DC Converter The PQ60260HTB10 PowerQor® Tera converter is a nextgeneration, board-mountable, isolated, fixed switching frequency dc/dc converter that uses synchronous rectification to achieve extremely high conversion efficiency. The power dissipated by the converter is so low that a heatsink is not required. However, this unit provides a baseplate for clamshell applications and optional heatsinking in severe thermal environments. The Tera series converters offer the maximum usable current output for any standard “half-brick” module. The Tera units also feature active current sharing for N+1 and parallel applications. RoHS Compliant see last page. Operational Features • Ultra-high efficiency, 92% at full rated load current • Delivers up to 250 Watts of output power with minimal derating - heatsink optional • Wide input voltage range: 35V – 75V, with 100V 100ms input voltage transient capability • Fixed frequency switching provides predictable EMI performance PQ60260HTB10 Module Control Features • On/Off control referenced to input side (positive and negative logic options are available) • Remote sense for the output voltage compensates for output distribution drops • Output voltage trim permits custom voltages and voltage margining Protection Features Mechanical Features • Industry standard half-brick pin-out configuration • Industry standard size: 2.3” x 2.4” (58.4 x 61.0mm) • Total height 0.50” (12.7mm) • Baseplate allows heatsink attachment or “clamshell” configuration • Total weight: 4.3 oz (122 g) • Input under-voltage lockout disables converter at low input voltage conditions • Output current limit and short circuit protection • Active back bias limit prevents damage to converter from external load induced pre-bias • Output over-voltage protection • Thermal shutdown Safety Features • 2000V, 30 MW input-to-output isolation • UL/cUL 60950-1 recognized (US & Canada), basic insulation rating • TUV certified to EN60950-1 • Meets 72/23/EEC and 93/68/EEC directives • Meets UL94V-0 flammability requirements Product # PQ60260HTB10 Phone 1-888-567-9596 Optional Features (full-feature) • Active current share for N+1 and parallel applications • External Clock Synchronization pin for better EMI characteristics • Startup Synchronization pin for more consistent start-up sequence • ORing FET drive supply for efficient ORing protection www.synqor.com Doc.# 005-2HTB26F Rev.
