Aims Power 5000 Watt Pure Sine Power Inverter NEGATIVE 48 Volt Rack Mount Inverter To 120 Volt AC – 2U (-48V) - PRM5KWN48120S

Ensure uninterrupted power with our advanced NEGATIVE 48V, 2U rackmount inverter, designed for telecom and data centers. Ideal for providing backup power to your essential equipment, this inverter generates 5000W of high-quality pure sine power at a stable 120Vac output. Thanks to the built-in 70 Amp transfer switch with a typical transfer time of less than 20ms, power is maintained seamlessly to your equipment. When city/utility power is available, it bypasses to provide consistent power. During outages, the inverter automatically switches to the backup DC power source, supplying power as long as the DC power supply provides enough voltage.

Monitoring is a breeze with the RS485 communication port, which offers real-time insights into DC input voltage, AC output voltage, frequency, and amps. Unmatched reliability, effortless integration, and consistent power supply ensure our rackmount inverter is the perfect solution for any setting where uninterrupted power is essential.

Maintenance Tips

• Install in a cool, dry, rack-mounted, and well-ventilated telecom cabinet to prevent overheating and airflow restriction.
• Regularly inspect -48V DC input terminals, bus bars, and grounding for tightness, corrosion, or heat discoloration.
• Keep air filters, vents, and internal fans clean to maintain stable cooling under continuous load.
• Monitor system via RS485 communication port to track input voltage, load, temperature, and fault conditions.
• Ensure DC supply stays within -41V to -60V operating range to avoid low/high voltage shutdowns.
• Periodically test automatic transfer/bypass function to confirm seamless switching during utility interruptions.
• Check output breakers and AC distribution for overload signs or tripping events.
• Schedule routine thermal inspections (especially under heavy load) to detect early signs of overheating.
• Verify rack mounting stability and cable strain relief in vibration-prone telecom environments.
