Value that Tonhe Delivers to Customers
1.Cut Energy Consumption & Reduce OPEX
Self-developed LLC resonant soft-switch & SiC technology achieve peak efficiency over 97%. Intelligent module sleep strategy optimizes PUE and lowers annual electricity bills. Low THD and wide AC input range help avoid grid penalty.
2.Higher Power Reliability & Less Downtime Loss
N+1 modular redundant design. Potting process, wide temperature range (-40℃~75℃) and full protection circuits. Single module failure will not shut down the whole system, ensuring continuous operation for data centers, substations and charging stations.
3.Flexible Scalability & Fast Project Delivery
Pre-fabricated modular architecture, capacity expandable on demand. Hot-swappable modules. Shorten site installation & commissioning time. Customers can invest in phases to avoid over-capital expenditure. Open protocols (Modbus/TCP) for easy integration with existing monitoring systems.
4.Optimized Total Cost of Ownership (TCO)
Long-lifetime components, hot-swap maintenance without system power-off. Less spare parts and manpower required. CE, UL and other international certifications available to save compliance cost for global projects.
5.Customized Power Solutions for Special Scenarios
National Enterprise Technology Center with strong R&D team. Custom power conversion products for HVDC compute power, telecom power, grid DC system, EV charging, energy storage and special equipment to solve unique site challenges.
6.Stable Supply Chain & Global Service Support
Listed manufacturer with reliable mass production. One-stop service including pre-sales design, on-site commissioning and after-sales maintenance. Products exported to over 30 countries, familiar with international standards to reduce overseas project risks.
