Aerpro APC20A 20 AMP 24V TO 12V DC POWER CONVERTER

Install any 12V accessory in your 24V truck with professional-grade power conversion

Product Overview

The Aerpro APC20A is the essential power solution that bridges the gap between heavy-duty 24V truck electrical systems and the 12V accessories you want to install. This professional-grade DC-DC converter delivers clean, stable 12V power with enough capacity to run aftermarket stereos, GPS units, lighting, and other accessories without compromising your truck's electrical system.

Built with advanced switch-mode technology and housed in die-cast aluminium with IP68 waterproof protection, this converter is engineered for the harsh conditions of commercial trucking, mining, and heavy equipment applications. The dual constant and accessory wire outputs mean proper integration with accessories that need both continuous and switched power feeds.

Features & Benefits

• Massive 20A power capacity: 276W output handles multiple accessories simultaneously including power-hungry stereo systems
• Professional switch-mode design: Over 95% efficiency minimises heat generation and power loss for reliable operation
• Dual power outputs: Separate constant and accessory wires properly integrate with aftermarket electronics requiring both power types
• IP68 waterproof protection: Completely sealed against dust and water ingress for harsh industrial environments
• Multiple safety protections: Over-voltage, under-voltage, over-current, short-circuit, and over-heat protection prevent damage
• Wide input voltage range: 18 to 40V DC input handles voltage fluctuations in truck electrical systems
• Compact die-cast housing: Rugged 74x74x34mm aluminium case dissipates heat effectively while saving space

FAQ

What is the Aerpro APC20A?

A 24V to 12V DC converter with up to 20 amps, 276W, for running 12V stereos and accessories in 24V trucks and machinery.

Why does it have constant and accessory wires?

Constant goes to the head unit memory feed and accessory to the ignition switched feed, so the stereo keeps its settings and turns on and off with the key.

Is it protected?

Yes. Over current, over voltage, over heat and short circuit protection, an IP68 die cast aluminium case and an inline fuse.
