3KVA High-Frequency Inverter
IV3000HD/750V
Adhering to a modular design philosophy, the IV series high-frequency inverters for electric power systems utilize DSP digital control and high-frequency soft-switching technology to deliver high efficiency and reliability. The DC input and AC output are completely electrically isolated. Each inverter features a built-in CPU and utilizes LED indicators to display real-time operational status.
Product Features
High Efficiency & FlexibilitySoft-switching technology: The DC/DC conversion adopts advanced LLC resonant soft-switching technology, with efficiency greater than 90%.
01
Safety & ReliabilityInput and output electrical isolation: Complete electrical isolation between DC input and AC output, eliminating the need for an external isolation transformer and meeting the requirements for power inverters in integrated power supply designs.
02
Excellent PerformanceWide operating voltage range, with a DC input operating range of 450~800VDC, adapting to long-distance HVDC power supply and vehicle-mounted applications.
Fully digital control: Adopts TI's C2000 series DSP controller, responsible for overall module control, switching, and fault handling, ensuring excellent consistency and anti-interference capability.
03
Fan ControlFan control: The cooling fan adopts a combined speed regulation mode based on temperature and output power. When the heat sink temperature is low and under light load, the fan runs at low speed with very low noise (less than 45dB); when the output is heavily loaded or the heat sink temperature is too high, the fan runs with linear speed regulation, resulting in low noise and a long fan lifespan.
