The Hi-Link URB2412YMD-20WR3 is a high-performance, fully encapsulated 20W isolated DC-DC power converter engineered for demanding industrial, automotive, and telecommunication applications. Featuring a 2:1 wide input voltage range of 18V to 36V DC (24V nominal), it efficiently converts variable bus voltages down to a regulated 12V DC output delivering up to 1666mA (1.66A) of continuous output current.

Boasting an exceptional peak efficiency of up to 91%, the URB2412YMD-20WR3 minimizes power loss and heat dissipation, enabling fanless operation in tightly sealed industrial enclosures. Its high input-to-output isolation rating ($1500\text{V DC}$) eliminates ground loops, reduces line-noise interference, and shields sensitive control processing logic from high-voltage transients on the primary power bus.

Key Features and Benefits

• Ultra-High Efficiency (Up to 91%): High energy conversion reduces heat generation and improves overall system reliability.

• 2:1 Wide DC Input Range: Accepts $18\text{V DC}-36\text{V DC}$ ($24\text{V DC}$ nominal input), tolerating voltage fluctuations in industrial batteries and automotive electrical networks.

• 1500V DC Electrical Isolation: Protects load devices and processing electronics from primary-side voltage spikes and ground loop noise.

• Regulated 12V 1.66A (20W) Output: Provides stable voltage output under varying load conditions with low output ripple and noise.

• Full Hardware Protections: Features continuous short-circuit protection (with auto-recovery), input under-voltage lockout (UVLO), output over-voltage, and over-current protections.

• Remote Control Capability: Includes a dedicated Ctrl (Remote ON/OFF) pin to switch the power output on or off via low-voltage logic signals without disconnecting primary power lines.

• Potted Encapsulated Design: Flame-retardant plastic casing shields internal components against dust, moisture, vibration, and thermal stress.

Technical Specifications

Pinout & Wiring Guide

The URB2412YMD-20WR3 module features 6 DIP-packaged through-hole PCB pins:

Input Side:

• GND / -Vin (Pin 1): Primary DC Input Negative / Ground ($18\text{V}-36\text{V}$ return rail).

• +Vin (Pin 2): Primary DC Input Positive ($+18\text{V}$ to $+36\text{V DC}$).

• Ctrl (Pin 3): Remote ON/OFF Control (Leave open for normal operation; pull low to disable output).

Output Side:

• Trim (Pin 4): Output Voltage Adjustment (Optional resistor pin to fine-tune $12\text{V}$ output).

• 0V / -Vout (Pin 5): Isolated Secondary Output Ground ($0\text{V DC}$).

• +Vout (Pin 6): Regulated $+12\text{V DC}$ Output Rail.

Wiring Tip: For optimal EMC compliance in noisy industrial environments, place an external electrolytic capacitor across $+Vin$ and $-Vin$, as well as an inductor/LC filter across the output terminals.

Applications

• Industrial Automation & PLC Systems: Powers $12\text{V}$ control modules, relays, and human-machine interfaces from a standard $24\text{V}$ industrial power supply bus.

• Automotive & Commercial Vehicles: Steps down nominal $24\text{V}$ heavy-vehicle battery systems to supply $12\text{V}$ telematics, GPS trackers, and dash equipment.

• Distributed Power Architectures: Provides isolated $12\text{V}$ sub-rails in complex Multi-PCB setups to eliminate cross-talk and ground loop interference.

• Telecommunications & Networking: Converts intermediate bus voltages down to stable power rails for routers, switches, and remote transceiver hardware.
