- Medium to large cabinets (like industrial control cabinets or power distribution panels) often need 230V, 400V, or even 480V AC. These higher voltages support bigger cooling capacities and keep your system running smoothly.
Tip: If your cabinet sits outdoors or in a hot factory, always size up your cooling. More heat means you need more voltage and a stronger air conditioner.
Power Supply Match
Next, check what kind of power you have available at your site. Matching your aircon voltage to your existing supply makes installation easier and safer.
- Single-phase power is common in homes, small offices, and light-duty setups. You’ll usually see 115V or 230V AC units here.
- Three-phase power is standard in factories, plants, and large facilities. These setups can handle 380V, 400V, or 480V AC, perfect for heavy-duty cooling.
- DC power (12V, 24V, 48V) is popular for telecom, battery storage, and solar-powered enclosures. DC air conditioners are lighter and work well in remote or mobile applications.
If you’re not sure which to pick, look at your main breaker panel or ask your electrician. Choosing the right voltage keeps your system safe and avoids costly rewiring.
Note: Linkwell offers cabinet air conditioners in a wide range of voltages—AC and DC—so you can always find a model that fits your power setup. Their flexible mounting options (side, top, or door) make installation a breeze, even in tight spaces.
