Product Description

The 19V 2.1A (H) LG Adaptor is a premium switching power supply (SMPS) specifically designed for LG’s range of LED and LCD monitors. This "H" variant is optimized for high-efficiency power conversion, reducing energy waste and heat generation during long hours of display use. Delivering a stabilized 19V DC output, it protects sensitive internal logic boards and backlight drivers from AC mains noise and voltage spikes. The adapter features a specialized DC barrel jack with a central sensing pin, ensuring a firm electrical contact and preventing accidental disconnects that can cause data loss or screen flickering.

Key Features

Stabilized 19V Output: Engineered to provide a clean, ripple-free DC voltage, essential for maintaining the color accuracy and brightness of high-definition LG panels.
Intelligent Protection Suite: Features active circuitry for Over-Voltage Protection (OVP), Short-Circuit Protection (SCP), and Over-Temperature Protection (OTP).
Universal AC Range: Operates seamlessly on input voltages from 100V to 240V, making it ideal for use in regions with unstable power grids.
Low Standby Power: Meets Level VI efficiency standards, drawing minimal power when the monitor is turned off or in sleep mode.
Reinforced Cable Design: The DC output cable is equipped with industrial-grade strain relief to prevent internal wiring fatigue from repeated bending.

Technical Details

Connector Type: 6.5mm Outer Diameter / 4.4mm Inner Diameter with Center Pin.
Polarity: Center Positive (+), Outer Sleeve Negative (-).
Enclosure Material: Heat-resistant, high-impact ABS plastic.

Prototyping and Engineering Tips from Robogears

The "H" Advantage: The (H) designation often signifies a higher efficiency rating or a "High-Profile" build quality. This means the internal components (like the primary capacitor and switching MOSFET) are rated for higher durability than standard generic clones.
Verify the Pinout: CRITICAL: While this adapter fits most LG monitors, some specialized medical or industrial LG screens use different voltages. Always verify that your monitor's input label explicitly asks for 19V. Applying 19V to a 12V or 14V monitor will result in immediate hardware failure.
Current Headroom: This 2.1A adapter is a safe replacement for any LG monitor requiring 0.8A, 1.3A, 1.7A, or 2.1A. The monitor will only "pull" the current it needs. Never use a 1.3A adapter to replace this 2.1A unit, as the undersized adapter will blow its internal fuse or overheat.
Reducing Screen Noise: If you notice thin horizontal lines or "snow" on your screen, ensure the adapter is plugged into a properly grounded socket. The internal EMI filter in this adapter works best when the AC source is stable.
DIY Bench Power: Because of its stable 19V output, this adapter is an excellent source for DIY projects requiring a 19V rail, such as portable soldering stations (TS100/TS80P) or small Class-D audio amplifiers. Just ensure you use a matching 6.5mm x 4.4mm Female DC Jack.

Package Includes

1 x 19V 2.1A (H) LG Adaptor

Disclaimer: Indoor use only. Do not use in high-humidity areas or near water. Ensure the DC pin matches your monitor's port exactly to avoid mechanical damage. Always disconnect the adapter from the wall if it shows signs of excessive heat or emits a burning smell. Not suitable for devices requiring more than 2.1A of current.
