What this product is
What this product is
This industrial-grade standard 19-inch 2U rackmount pure sine wave power inverter is engineered for telecom shelters and industrial automation. Operating on a nominal -48V DC bus, it delivers a continuous 3000W 220V AC output through high-frequency galvanic isolation, featuring an integrated static transfer switch for sub-4ms bypass transfer.
What problem it solves
The HEFENGQI 48V to 220V 3kW rackmount inverter is tailored to meet the mission-critical uptime requirements of carrier-class installations and industrial control infrastructures. Powered by high-speed dual DSP architecture, it converts nominal -48V battery bus power into ultra-clean 220V AC power with total harmonic distortion (THD) under 3% and a peak operating efficiency exceeding 92%. Equipped with a fast static transfer switch (STS), the system ensures seamless grid-to-inverter switching within 4ms, preventing unexpected reboots or disruptions to sensitive servers and network transmission nodes. The front-panel high-definition LCD display provides real-time telemetry, including input/output electrical parameters, load percentage, and detailed alarm status. The mechanical design complies with severe electromagnetic compatibility (EMC) standards and houses robust protective circuitry: DC polarity reverse protection, over/under-voltage shutdown, overload, short-circuit, and smart temperature-triggered thermal throttling. Standard isolated RS485 interfaces running Modbus-RTU alongside optional SNMP cards enable seamless integration into central telecom power environment monitoring systems across a broad operating temperature range of -20°C to +55°C.
