12V 3A Power Adapter

LTRONIX 12V 3A Power Adapter – Safe, Universal, and Reliable

The LTRONIX 12V 3A Power Adapter is a Switch Mode Power Supply (SMPS) that converts AC mains power (100–240V, 50/60Hz) to a stable DC output of 12 volts at 3 amperes (36 watts). It uses a 2.5mm × 5.5mm center-positive DC barrel connector and is designed for continuous operation with devices such as Wi-Fi routers, CCTV cameras, DVR/NVR systems, 12V LED strip lights, modems, set-top boxes, and 12V DIY electronics. Built-in protections include overload, overvoltage, short-circuit, and thermal cutoff circuits.

Frequently asked questions

Can I use a 12V 3A adapter on a device that needs only 12V 1.5A or 12V 2A?

Yes. The 3A rating is the maximum current the adapter can supply,
not what it forces into the device. Your device draws only what it needs.
Using a higher-amperage adapter is safe and often preferable — it runs
cooler and with less electrical stress.

What connector size does this adapter use?

The LTRONIX 12V 3A adapter uses a standard DC barrel connector with a
5.5mm outer diameter and 2.5mm inner diameter (center
positive). This is the most common connector size for routers, CCTV systems,
and LED controllers in India. It is also compatible with 5.5mm × 2.1mm
sockets.

What is the difference between a 12V 3A and a 12V 5A power adapter?

Both output 12V DC, but differ in maximum wattage. A 12V 3A adapter
delivers up to 36W — sufficient for a single router, modem,
or CCTV camera. A 12V 5A adapter delivers up to 60W, suited
for multi-camera CCTV setups or longer LED strip installations. Always match
the adapter wattage to at least the total load of connected devices.

What is an SMPS adapter and why is it better?

SMPS (Switch Mode Power Supply) adapters are more efficient (85–92%) than
traditional transformer adapters (60–75%). They are lighter, run cooler,
produce cleaner DC output with low ripple, and support a wide input range
(100–240V). This makes them ideal for continuous use in routers and
security systems.

Does this adapter work with Indian power sockets?

Yes. It accepts 100–240V AC input at 50/60Hz, making it
fully compatible with Indian 230V, 50Hz power sockets. It includes a
standard Indian 3-pin plug.

Is it safe to leave plugged in 24/7?

Yes. The built-in overload, overvoltage, short-circuit, and thermal
protection circuits allow safe continuous operation. It is designed for
always-on applications like CCTV cameras, routers, and modems.

Which router brands is this adapter compatible with?

This adapter is compatible with any router requiring 12V DC power with a
2.5mm × 5.5mm connector, including models from TP-Link, D-Link, Tenda,
Netgear, Asus, Jiofiber ONT boxes, Airtel routers, and most BSNL modems.
Always verify your router’s required voltage and current before use.

What warranty does the LTRONIX 12V 3A adapter come with?

Every LTRONIX 12V 3A Power Adapter comes with a 1-year manufacturer
warranty. If your adapter has a defect or performance issue within
the warranty period, contact Ltronix India support for a replacement.
