Frequently Asked Questions

AC/DC Industrial Rectifiers FAQ

What is the difference between SiC Modular rectifiers and Thyristor rectifiers?
Silicon Carbide (SiC) rectifiers operate at high switching frequencies, providing higher energy efficiency (>96%), smaller footprint, lighter weight, and modular hot-swap capabilities. Thyristor rectifiers use line-frequency semiconductor switching, providing extremely high physical robustness, high surge current tolerance, and maximum longevity in extreme electrical environments.
Can Premium PSU rectifiers be integrated into existing SCADA networks?
Yes. FlexStorm systems feature an integrated Web Server and support industrial communication protocols including Modbus TCP, Modbus RTU, SNMP, and CANbus, allowing seamless integration with SCADA, DCS, and IoT monitoring platforms.
Are these rectifier systems suitable for station battery charging?
Both FlexStorm and ThyriStorm series feature advanced digital battery controllers supporting IUoU charging profiles, automatic temperature compensation, battery discharge testing, and low-voltage disconnect (LVD) protection for lead-acid, NiCd, and lithium-ion battery banks.
