DPS LED48-500 Buck DriverDIN Rail

Functional description

Overview

The LED48-XXX device is a 48V input 350mA / 500mA DIN Rail buck converter providing low ripple constant current output. It's intended use are tight control cabinets, equiring an aditional current driver. The functional input voltage ranges from 5V to 48V. When the output voltage and current is achieved, a green led lights up.

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

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 U_in,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.

Specification
