Battery Charger 21kw Single Phase Rectifier
The SANDI SERIES 21kW single-phase rectifier is a high-efficiency charging module designed for electric vehicle charging stations. It operates with a single-phase AC input without a neutral conductor, delivering up to 20kW of output power under standard conditions. The module features hot-plug technology, allowing for easy installation and maintenance without disrupting the system’s output voltage.
Advanced current-sharing technology enables multiple modules to automatically balance load within 10 seconds, with an unbalance degree of less than ±0.5A. The unit supports a wide input voltage range of 260Vac to 450Vac, with power output adjusting dynamically to maintain stability. Output voltage can be regulated from 50Vdc to 750Vdc in 0.1Vdc increments, and the module includes comprehensive protection features such as input overvoltage, output overvoltage, short-circuit, and over-temperature safeguards.
This rectifier is ideal for industrial and commercial EV charging applications where high power density and low harmonic distortion are critical. Its temperature-limited power control and fan-speed regulation ensure optimal performance under varying thermal conditions. Buyers should confirm compatibility with their charging infrastructure and request detailed technical documentation for integration.

Sourcing Battery Charger 21kw Single Phase Rectifier from Zhejiang Sandi Electric Co., Ltd - China Import Guide
Before ordering, confirm the rectifier’s compatibility with your charging infrastructure by verifying the input voltage range, output power, and connector specifications. Request a detailed datasheet and, if possible, a sample for on-site testing to ensure seamless integration with your system.
For logistics, discuss lead times for bulk orders, as high-power rectifiers may have longer production cycles. Clarify the available Incoterms (e.g., FOB Ningbo) and whether the supplier can handle international shipping and customs documentation. Packaging should be robust to prevent damage during transit, especially for sensitive electronic components.
Quality checks should include testing the module under full load to verify its output stability and protection features. Inspect the cooling system to ensure it can handle the thermal demands of your application. Request third-party certifications for safety and performance, and confirm that the supplier provides a warranty or service agreement for post-purchase support.
