Description

It's intended use are tight control cabinets, requiring an aditional lower output voltage. The functional input voltage ranges from 2V above the desired output voltage to 48V. When the output voltage is present, a green led lights up. The device is resiliant to typical operating failures: Input reverse polarity, output short circuit, open circuit, moderate input transients and moderate output transients. The device offers solid output voltage stability over the complete output current range. The device may be operated at ambient temperatures between -40°C und 50°C.

Functional description

Overview

The DCC48xx is a 48V input 5V / 12V / 24V DIN Rail Buck converter providing 1A of output current. It's intended use are tight control cabinets, requiring an aditional ower output voltage. The functional input voltage ranges from 2V above the desired output voltage to 48V. When the output voltage is present, a green led lights up.

The device is resiliant to typical operating failures: Input reverse polarity, output short circuit, open circuit, moderate input transients and moderate output transients.

The device offers solid output current stability over the complete input voltage range. The device may be operated at ambient temperatures between -40°C und 50°C.

Protections

The following output protections are in place:

  • Input Reverse polarity: The input may be connected in reverse polarity with an input of Uin,max = -48 V.
  • Short circuit proof: The output of the converter can be shortcircuited without problems for infinite time.
  • Open circuit proof The output may be operated in open circuit for infinite time.
  • Input TVS diode The converter features an input TVS diode for protection.
  • Output TVS diode The converter features an output TVS diode for protection.
