Key features
- Wide input range: 16–58V DC, covering 24V, 36V and 48V systems.
- Fixed 12V output: up to 10A and 120W maximum.
- High efficiency: up to 95% conversion efficiency for less wasted energy and less heat.
- IP68 waterproof housing: aluminum shell with silicone potting, so it can work in the rain and is shockproof, moisture-proof and dust-proof.
- Good heat dissipation: the aluminum case spreads heat for a longer service life.
- Wide temperature range: case operating temperature from -40 to 85°C.
- Lightweight: only 280 g.
Intelligent protection
The converter protects both itself and your accessories with overcurrent, overload, low-load, short-circuit, undervoltage and intelligent overheating protection. When the equipment returns to normal operation, the converter resumes working automatically, with no manual reset required.
Typical applications
- 12V accessories on 24V, 36V and 48V battery systems, such as lights, USB chargers, small audio equipment and horns, within the 10A limit
- Golf carts, light electric vehicles and other automotive uses
- Surveillance and camera systems
- LED products and LED strips
- Instruments, meters and low-power test systems
- Cable TV and similar low-power equipment

Installation notes
Check that your battery's highest voltage stays within the 58V input limit, remembering that a fully charged 48V (16-cell) lithium pack, or a pack under regenerative braking, can reach close to or above that figure. Make sure the total current drawn by all 12V accessories stays within 10A (120W), and use correctly sized wire and an inline fuse on the input side. Observe polarity when connecting, and secure the converter so it cannot move or pull on the wires. Although the housing is IP68-rated, route the cables so that water cannot run along them into the connectors, and keep the terminals themselves protected.
