24V to 12V Buck Converter

This buck converter steps a 24V nominal supply down to a regulated 12V output at up to 10A. The non-isolated module accepts an input range of 20V to 30V and delivers 120W continuous power. It is suited for golf cart accessories, LED lighting and other 12V loads in mobile or outdoor environments.

Suits mobile 12V loads.

The IP68-rated aluminium housing with epoxy potting resists water, dust and shock from -40°C to 80°C. Synchronous rectification reaches 95% efficiency with 50mV ripple. Built-in protection covers over-current, overload, short-circuit and over-temperature events. Buyers requiring galvanic isolation or an input above 30V must choose a different topology.

120W at 12V 10A output

The single figure that decides fit is the 120W output rating at 12V 10A. If the connected equipment draws more current or requires a different voltage, this module will not support it..verify the load stays within 10A and the source stays within 20V to 30V before installation.

Questions about this item

What are the exact dimensions of the THJ2412B120Z converter so I can check if it fits my mounting space?

The unit measures 2.5 in x 2.1 in x 0.7 in and weighs 110 grams. Its compact aluminium shell with epoxy potting is designed for tight installations.

How do I wire the THJ2412B120Z correctly and what is the common mistake to avoid?

Connect a 20V to 30V DC source to the input terminals observing polarity; the module outputs 12V ±2% at up to 10A after a 2S start delay. The frequent error is reversing input polarity or exceeding the 30V maximum.

Does the THJ2412B120Z require any periodic maintenance or component replacement?

No user-serviceable parts exist inside the fully potted IP68 module. The synchronous rectification design and over-heat protection run maintenance-free across the -40°C to 80°C operating range.
