Wi-Tek - WI-DP30W-12V - 12V DIN-rail Power Adapter
Product Overview
WI-DP30W-12V is a compact DIN-rail power adapter designed to provide stable DC power for industrial switches and other equipment. It delivers an adjustable 10.8-13.8 V DC output at up to 2.5 A, with a maximum rated power of 30 W, and supports wide-range AC or DC input.
Key Configuration
Model: WI-DP30W-12V | Output: 12 V DC, 0-2.5 A, 30 W max | Input: 90-264 V AC, 47-63 Hz, or 127-370 V DC | Adjustment: 10.8-13.8 V DC | Installation: DIN-rail mounting | Protection: Short circuit, overload, and over-voltage protection
Key Features
- · Provides 12 V DC output with adjustable voltage from 10.8 V to 13.8 V
- · Delivers up to 2.5 A rated output current and 30 W maximum power
- · Supports universal 90-264 V AC input for global mains compatibility
- · Supports 127-370 V DC input
- · Provides typical efficiency of 88%
- · Maintains maximum ripple and noise of 120 mVp-p
- · Includes overload protection from 105%-160% of rated output power with automatic recovery
- · Includes over-voltage protection with output 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 adapter to match the voltage requirements of compact industrial switches and other DC equipment. Overload protection combines hiccup-mode operation and constant-current limiting, while over-voltage protection shuts down the output and requires repowering after the fault condition is removed.
Installation Notes
The adapter is intended for DIN-rail installation and measures 35 x 90 x 58 mm, with a product weight of 120 g. Provide 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 under low input voltage or at elevations above 2000 m.
