DROK 12V Boost-Buck Converter 9–36V 10A 120W

The DROK Boost Buck Converter is a compact, IP67-rated DC-DC module that delivers a stable 12V output from 9–36V inputs up to 10A (120W).

Designed for vehicle electronics, solar arrays and portable displays, this aluminium-shell regulator maintains a steady 12V rail whether the source voltage is above or below 12V. Encapsulated for weather resistance and built with high-efficiency circuitry, it reduces heat and keeps sensitive equipment powered in demanding environments.

How does this module keep devices running from varying battery voltages?

The unit combines boost and buck regulation so it can step voltage up or down to a fixed 12V output automatically. High integration and synchronous rectification produce conversion efficiency above 90%, helping preserve battery energy and reduce thermal loss.

• Input range: DC 9V–36V suitable for 9V, 12V, 24V and 36V systems.
• Stable output: fixed DC 12V at up to 10A (120W).
• High efficiency (>90%) minimizes wasted power and heat.
• Quiescent draw under 10mA keeps standby drain low.

What protections and durability features are included?

The DROK converter is potted and enclosed in an aluminium shell with IP67 sealing to resist water, dust and vibrations. Built-in protective circuits guard against over-current and overheating for safer operation in harsh or mobile installations.

• IP67 waterproof and dustproof design for outdoor or automotive use.
• Over-current protection and thermal shutdown to protect loads and the module.
• Rugged potting reduces moisture ingress and mechanical stress.
• Operating range -25°C to 65°C with storage -40°C to 80°C.

How should I wire and install the converter for reliable performance?

Follow the wiring diagram exactly and use short, heavy-gauge wires on both input and output to limit voltage drop and preserve output voltage under load. Do not parallel multiple outputs, and leave a safety margin on the upstream power supply so it can handle continuous operation.

• Recommended: thick, short input/output cabling to minimize losses.
• Do not combine multiple output terminals into one load.
• Mount using the supplied ear (0.16" diameter) and allow airflow around the unit.
• Non-isolated design: grounds may be tied together when required.

What real-world applications is this regulator best suited for?

This converter is engineered for electronics that demand a stable 12V supply from variable sources: vehicles, solar setups, signage and embedded displays. Its small footprint and weatherproofing make it practical for cramped, exposed or mobile installations.

• Car audio, radios, in-vehicle displays and taxi advertising screens.
• LCD/LED displays, CCTV monitors and intercom systems.
• Solar PV systems and auxiliary 12V loads on recreational vehicles.
• Industrial or outdoor electronics that require IP67 protection.

Who is this for: installers, hobbyists and fleet technicians who need a compact, reliable means to produce regulated 12V from a wide DC input range will value the DROK 120W stabilizer. It’s especially useful where space is limited and equipment must remain operational in wet, dusty or vibration-prone conditions. Note that this is a non-isolated module — follow grounding and wiring guidance for safe integration into your system.
