✅ Wide Input Range – 17v to 60v
Works with 24V, 36V, 48V nominal systems (e.g., 18V, 20V, 24V, 36V, 48V batteries). Ideal for electric golf carts, forklifts, solar arrays, and heavy‑duty trucks.
✅ Powerful Output – 12v 20a (240w)
Plenty of juice to run LED light bars, stereo systems, surveillance cameras, fans, pumps, or a bank of LED strips.
✅ Synchronous Rectification – 95% Efficiency
Less energy lost as heat means your battery lasts longer. Runs cool even at full load.
✅ Waterproof & Rugged – Ip67‑Style Sealing
Fully potted in an aluminum case with silicone seal. Resists water splashes, dust, vibration, and temperature extremes (-40°C to 80°C). Mount it under the hood or on a golf cart frame without worry.
✅ Multiple Protections
Input undervoltage
Overload & overcurrent
Overheat
Output short‑circuit
These safeguards protect both the converter and your connected equipment.
✅ Low Noise – 50mv Ripple
Clean 12V power, safe for sensitive electronics like radios, screens, and GPS units.
✅ Fast Start – ≤2 Seconds
No annoying delay – power comes on almost instantly.
