The QLS30 series uses fewer components than any other equivalently rated single board converter.
The converters can deliver a maximum of 30 Amps with a typical efficiency of 85%.
The QLS provides superior thermal performance, with minimal derating.
The QLS30ZB model converter can deliver 22.
8 amperes at 1.
8 volt output in ambient conditions of 65°C and 200 LFM.
This full featured, low profile converter offers input undervoltage lockout, overload, overvoltage and overtemperature protection.
Interface features include remote on/off, remote sense and output voltage trim.
