Wi-Tek - WI-DP75W-48V - 48V DIN-rail Power Adapter
Product Overview
WI-DP75W-48V is a DIN-rail power adapter designed to provide stable DC power for industrial equipment and switches. It delivers an adjustable 48-55 V DC output at up to 1.6 A, with a maximum rated power of 76.8 W, and supports universal AC input from 90-264 V.
Key Configuration
Model: WI-DP75W-48V | Output: 48 V DC, 0-1.6 A, 76.8 W max | Input: 90-264 V AC, 47-63 Hz, or 127-370 V DC | Adjustment: 48-55 V DC | Installation: DIN-rail mounting | Protection: Short circuit, overload, over-voltage, and over-temperature protection
Key Features
- · Provides 48 V DC output with adjustable voltage from 48 V to 55 V
- · Delivers up to 1.6 A rated output current and 76.8 W maximum power
- · Supports universal 90-264 V AC input for use with global mains voltages
- · Supports 127-370 V DC input
- · Provides typical efficiency of 88.00%
- · Includes short circuit and overload protection with automatic recovery after fault removal
- · Includes over-voltage and over-temperature protection with shutdown and restart recovery
- · Supports operation from -20°C to 70°C with 20%-95% non-condensing humidity
Technical Context
The adjustable DC output allows the power adapter to be matched to the voltage requirements of industrial switches and other DC equipment. Short circuit, overload, over-voltage, and over-temperature protection help limit damage during abnormal operating conditions, while the 150 mVp-p maximum ripple and noise specification supports stable power delivery.
Installation Notes
The adapter is intended for DIN-rail installation and weighs 0.51 kg. Provide installation clearances of at least 40 mm above, 20 mm below, and 5 mm on each side; increase side clearance to 10-15 mm when adjacent equipment is a heat source. Derating may be required at low input voltage or at elevations above 2000 m.
