QLS30ZY-NT

FE The QLS30 Series of single output DC-DC converters features single board, multi-layer construction and an SMT design that is highly reliable due to the low component count and minimal manufacturing touch time. The QLS30 Series uses fewer components than any other equivalently rated single board converter. LI The converters can deliver a maximum of 30 amps with a typical efficiency of 85%. The QLS provides superior thermal performance, with minimal derating, and can deliver 22.8 amperes at 1.8 volt output in ambient conditions of 65°C and 200 LFM. EN D O F This full-featured, low-profile converter offers input undervoltage lockout, plus overload, overvoltage, and overtemperature protection. Interface features include remote on/off, remote sense, and output voltage trim.  RoHS lead solder exemption compliant  Cost-effective single board design  Low profile – 11 mm height  Input/output isolation: 1500 VDC, Basic insulation  High efficiency  Output back-drive protection  Start-up into high capacitive load  Low conducted and radiated EMI  Output overcurrent protection  Output overvoltage protection  Overtemperature protection  Remote sense  Set point accuracy ±1%  Remote on/off (primary referenced), positive or negative logic  Output voltage trim adjust, positive or negative  Approved to the latest edition of the following standards: UL/CSA60950-1, IEC60950-1 and EN60950-1.
