Alfatronix PV24S PowerVerter
24V-to-12V Non-Isolated DC Converter | 24A Continuous | 288W
The genuine Alfatronix PV24S PowerVerter supplies 12V equipment from a nominal 24V DC electrical system. Its sealed, fanless construction, protected electronics and Click ’n’ Fit mounting clip suit commercial vehicles and properly protected marine installations where a common-negative, non-isolated converter is appropriate.
Key Features
- ✔ 24A continuous output: Powers multiple compatible 12V loads up to 288W combined.
- ✔ Non-isolated design: Common-earth topology for installations that do not require galvanic separation.
- ✔ Protected electronics: Current limiting, thermal limiting, transient filtering and internal input/output fuses.
- ✔ Fanless IP53 enclosure: Anodised aluminium and glass-filled polycarbonate construction.
- ✔ Fast installation: Click ’n’ Fit three-hole mounting clip and green output-status LED.

Compatibility / Fitment Guide
| Check | Required specification | Fitment decision |
|---|---|---|
| Supply system | Nominal 24V DC; operating range 17–32V DC | Suitable for 24V commercial-vehicle and vessel electrical systems within this range. |
| Connected equipment | 12V equipment rated to accept 13.6V DC; combined continuous draw ≤24A / 288W | Add the maximum current of every simultaneous load, including start-up demand. |
| Intermittent demand | Maximum 30A for 2 minutes, followed by 8 minutes rest | Do not treat the 30A figure as a continuous rating. |
| Electrical isolation | Common negative / no galvanic isolation required | If isolation between input and output is required, select the isolated PV24i instead. |
| Mounting environment | Protected location; 167 × 87 × 50mm plus wiring clearance | IP53 resists limited dust and water spray; it is not an immersion or exposed-deck rating. |
Not suitable for: 12V-to-24V conversion, charging batteries, 230V AC equipment, loads above 24A continuous, installations requiring galvanic isolation, or locations exposed to immersion. Cable size and external circuit protection must be selected for the installation and load.

Frequently Asked Questions
Will this run any 12V appliance from a 24V battery bank?
Only if the appliance accepts a nominal 13.6V supply and the total simultaneous load, including starting current, stays within the converter rating.
Is the output electrically isolated from the input?
No. PV24S is the non-isolated, common-earth version. Use PV24i where galvanic isolation is required.
Can it provide 30A continuously?
No. Alfatronix rates it at 24A continuous. The 30A intermittent rating is limited to two minutes followed by eight minutes rest.
Can it be mounted outdoors?
IP53 does not make it waterproof or submersible. Install it in a protected, ventilated location and allow adequate cable clearance.
Installation note: Confirm load current, conductor size, fuse protection, polarity and earthing arrangement before energising the converter.
