Product Overview
MFA Series split DC air conditioner separates the evaporator indoor unit from the condenser outdoor unit, delivering 2600-5000 W cooling capacity on 48VDC input for telecom base station equipment rooms and larger outdoor cabinets. The split design places the cooling side inside the equipment space and rejects heat outside, which suits enclosures that are too large or too hot for a compact monoblock cabinet cooler — and because it runs on 48VDC, it connects directly to the telecom power bus used across solar and hybrid sites.
Key Features
- Split architecture: indoor evaporator unit + outdoor condenser unit, flexible placement for large enclosures
- 48VDC input: direct connection to the telecom -48VDC power bus
- 2600-5000 W range: covers large equipment rooms and multi-bay outdoor cabinets
- Wide temperature range: -40 °C to +55 °C operation
- Eco refrigerant: R134a; RS485 remote monitoring and multi-function alarm output
- Low noise indoor side: compressor and condenser fan move outside the equipment space
Model Range & Specifications
| Model | Cooling Capacity (W) | Input | Indoor Unit (mm) | Outdoor Unit (mm) |
|---|---|---|---|---|
| MFA2600 | 2600 | 48VDC | 290×800×190 | 295×850×198 |

All models use R134a refrigerant, operate from -40 °C to +55 °C and provide RS485 status reporting with multi-function alarm output; OEM dimensions are available on request.
Split DC vs. Monoblock Cabinet Coolers
Monoblock cabinet air conditioners such as the MPD Series mount wholly on the cabinet side and work best up to about 5 kW in standard cabinets. The MFA split design moves the compressor and condenser outside: the indoor unit is a slim wall-mounted evaporator, while the outdoor unit rejects heat to open air. This layout suits equipment rooms and large integrated cabinets where a monoblock would block space or where noise inside the room matters. The 48VDC input keeps it compatible with telecom power systems — pair it with 48V rectifier cabinets and battery banks on the same bus.
How to Select the Right Model
Size on total equipment heat load with the unit rated at 1.2-1.5 times the internal load, and confirm refrigerant line length between indoor and outdoor units fits the site layout (standard pre-charged line sets are used for factory OEM orders). MFA2600 covers small equipment rooms and single outdoor cabinets; MFA4000 and MFA5000 serve larger base station rooms, multi-bay cabinets and small pop-up data shelters.
Applications
- Telecom base station equipment rooms on -48VDC power systems
- Large outdoor integrated cabinets and multi-bay equipment enclosures
- Small pop-up and edge data shelters
- Solar and hybrid-powered sites requiring high-capacity DC cooling

Frequently Asked Questions
Q: When should I choose a split DC unit instead of a monoblock cabinet air conditioner?
A: Choose the split MFA when the enclosure is large (multi-bay cabinets, equipment rooms, shelters), when a monoblock unit would take too much side-panel space, or when you need the compressor noise and heat outside the equipment space. For standard cabinets up to 5 kW, a monoblock unit like the MPD Series is usually simpler.
Q: Does the indoor unit work with the same 48VDC bus as the rectifiers?
A: Yes. Both indoor and outdoor units run on 48VDC input and connect to the telecom -48VDC power bus, so the split system integrates with 48V rectifier cabinets and battery systems without an inverter.
