400V Low Voltage Static Converter for Auto


Product Features


Precision Voltage Regulation

Delivers stable 400V three-phase output with voltage regulation within ±1% of setpoint, ensuring consistent power supply for sensitive automotive equipment such as robotics, welding systems, and test instruments. Total harmonic distortion (THD) is less than 3% at full load.


High Conversion Efficiency

Boasting conversion efficiency exceeding 96% across a wide load range (20-100%), the static converter minimizes energy losses compared to traditional motor-generator sets, reducing operating costs and heat generation in production facilities.


Fast Response Characteristics

Features a transient response time of less than 5ms to load changes, maintaining stable output voltage during sudden current fluctuations common in automotive manufacturing processes such as robotic welding and material handling.


Comprehensive Protection Systems

Equipped with multi-layer protection including overvoltage, undervoltage, overcurrent, short circuit, overheating, and phase loss protection. Isolation monitoring ensures safety in accordance with automotive industry electrical safety standards.


Applications


Automotive Production Lines

Provides reliable power for robotic assembly systems, conveyor belts, and automated machinery in vehicle manufacturing plants, ensuring consistent performance and reducing production downtime.


Component Testing Facilities

Powers automotive component test benches for engines, transmissions, and electrical systems, delivering precise voltage regulation required for accurate testing and certification processes.


Paint Shop Equipment

Supports specialized equipment in automotive paint shops including spray booths, ventilation systems, and curing ovens, with low electromagnetic interference to prevent disruption of sensitive coating processes.


Electric Vehicle Testing

Enables safe, controlled power supply for electric vehicle (EV) and hybrid vehicle testing systems, including battery testing, motor drive testing, and charging system validation.


FAQ


What input voltages does the converter accept?

The converter accepts standard single-phase or three-phase input voltages ranging from 200V to 240V AC (50/60Hz) and converts them to regulated 400V three-phase output, making it compatible with standard industrial power supplies worldwide.

How does the static converter differ from traditional motor-generator sets?

Unlike motor-generator sets, static converters have no moving parts, resulting in higher efficiency (96% vs. 80-85%), lower maintenance requirements, reduced noise levels, and faster response to load changes.

What is the maximum current output of the converter?

Available models provide continuous current outputs from 10A to 100A at 400V three-phase, corresponding to power ratings from 7kVA to 70kVA, accommodating various automotive equipment requirements.
