OPTIONS
Positive or Negative On/Off logic
The Delphi series Q48SC12042, quarter brick, 36~75V input,
Droop current sharing
single output 12V, are full digital control DC/DC converter, and
Digital pins
are the latest offering from a world leader in power system and technology and manufacturing ― Delta Electronics, Inc. This product provides up to 500 watts of power at 36~75V input in an industry standard, DOSA compliant footprint and pin out. The Q48SC12042 offers more than 95.0% high efficiency at 48V input, 12V output and 42A load. There is a built-in digital PWM controller in the Q48SC12042 series, which is used to complete the Vo feedback, PWM signal generation, droop or active
