FO-DC outdoor cabinet air conditioners
DC-powered cabinet air conditioners delivering 600 to 3000 W of cooling directly from the −48 VDC site supply, with no inverter required. IP55 closed-loop monoblocks that keep dust and moisture away from the equipment inside outdoor enclosures.
What this range delivers
Five models sharing one platform: true DC compressors and speed-adjustable DC fans, aluminum micro-channel condensers, RAL 7035 powder-coated housings, RS485 plus dry-contact communication and a 10+ year expected service life. The flagship FO-DC3000 is rated at an EER of 11.86 BTU/W·h (T1) with a COP of 2.54 (T3).
Runs on −48 VDC
True DC compressor and fans on the 40 to 60 V site supply; no inverter, soft-start protects the site bus.
IP55 sealed loop
Closed-loop monoblock separates inside air from outside air, protecting electronics from dust and moisture.
Door-mount flange
Integrated flange for through-wall mounting on the cabinet door; plug-and-play commissioning.
Site-grade monitoring
RS485 and dry-contact alarms with auto-recovery and multi-protection functions.
FO-DC Series: cabinet cooling for off-grid sites
True DC operation
DC compressor and DC fans run straight from the −48 VDC site supply (40 to 60 V) with no inverter, soft-start included, drawing as little as 200 W.
Sealed door-mount design
Closed-loop monoblock with integrated flange for through-wall mounting on the cabinet door; IP55, RAL 7035 powder-coated steel, aluminum micro-channel condenser.

Sealed, DC-native, field-proven design
- True −48 VDC operation · DC compressor and fans run from the site battery bus; no inverter losses, no extra failure point.
- Soft start · Prevents inrush current from disturbing site power during compressor starts.
- Aluminum micro-channel condenser · More heat exchange in less depth, resistant to corrosion.
- Closed-loop IP55 monoblock · Inside air never mixes with outside air; dust and moisture stay out of the cabinet.
- Flange door mounting · Through-wall installation on the cabinet door, plug-and-play commissioning.
- Auto-recovery protection · Multifunction alarms, RS485 and dry contacts, automatic restart after power events.
