AC to DC Converter 3000w

Product Overview
Tonhe 3000W AC-DC converter is a modular rectifier for critical infrastructure power conversion, converting AC mains into stable DC output.
Supports N+1 / N+M parallel redundant operation, flexible capacity expansion from 3kW up to hundreds of kW.
Available in mainstream DC versions: 48VDC for telecom, 220VDC for power substation control.
Core Technical Features
Topology: Vienna PFC + LLC resonant converter, peak efficiency ≥96%, PF＞0.98, THD＜5%.
Wide AC input range, adapts to different national grid standards; works well under unstable mains in remote areas.
Full digital DSP control, real-time voltage/current/temperature monitoring, active automatic current sharing.
Built-in protections: over-voltage, over-current, short-circuit, over-temperature, battery reverse polarity.
Communication: Modbus-RTU / RS485 interface, compatible with SCADA & remote site monitoring.
Full potting design: shock, dust and moisture resistant, suitable for high-temperature, coastal and high-altitude environments.
CE certified, complies with international EMC standards for EU, Southeast Asia, Australia and Latin America deployment.
Overseas Application Cases
1.Southeast Asia Telecom Cell Sites (48V model)
Multiple remote tower projects adopted Tonhe 3000W modules with lithium/lead-acid battery backup. Wide input voltage handles frequent grid fluctuation. Remote monitoring cuts on-site maintenance visits by over 60%.
2.Australia Distribution Substation (220VDC model)
Modules supply power for relay protection and circuit breaker closing. Supports short-time high impulse current, robust design for outdoor power cabinets, meets local utility reliability requirements.
3.Europe Edge Data Center & Hybrid Microgrid
Paired with solar inverters and diesel generators. Modular scaling reduces upfront CAPEX. High efficiency lowers heat generation and cooling costs inside compact server cabinets.
