Features Technical Indicators Overall Dimension

1. Emergency repair of urban power grids
The generator truck is connected to the distribution network to replace the faulty line power supply (supporting 0.4kV/10kV voltage level).
2. Power supply for major events
Multiple generator trucks are operated in parallel, and power is evenly distributed through master-slave control (circulation suppression <5%).
3. Power supply in remote areas
Microgrids are formed with photovoltaic/energy storage to support long-term stable operation in off-grid mode.
Product technology highlights
Quick plug-in interface: standard industrial-grade IP67 grid-connected socket, resistant to 1000 plug-in and pull-out.
Adaptive synchronization: built-in DSP digital phase-locked loop, frequency tracking accuracy ±0.02Hz.
Intelligent alarm: LED screen display + sound and light alarm, real-time prompt of phase reverse connection, abnormal grounding and other faults.
Mobile adaptation: anti-seismic design (IEC 60068-2-6 standard), support vehicle bumpy environment.
