Rack Mount DC AC Inverter Features
Built-in Toroidal Transformer
Enhances conversion efficiency, reduces electrical noise, and ensures a stable, low-distortion sine wave output.
Continuous output
3000 W continuous power, with higher short-term surge capacity (9000W peak) for motor starts and compressor inrush.
48V DC input
Direct connection to common telecom and battery backup systems (lead-acid, AGM, gel, or Li-ion banks sized for 48V).
Rack-mount 3U form factor
Space-efficient 19″ rack compatibility for neat integration into standard cabinets.
Smart LCD + LED Display
Real-time monitoring of input/output voltage, load level, battery status, and operational mode.
Protections
Overload, short-circuit, over/under-voltage, over-temperature, reverse polarity, and ground-fault protection to protect both inverter and connected loads.
