Regulated DC/DC converter TH30F10030C9E-WT

high-powerhigh-voltagefor EV charger

Product overview
TH30F10030C9E-WT is a 30 kW DC power module designed for EV charging stations. It accepts 285–475 VAC three-phase four-wire input (rated 380 VAC) and delivers a rated DC output power of 30 kW with a constant-power region from 300 VDC to 1000 VDC. The module operates up to +50°C ambient without derating across the full output range and features fan cooling with very low standby power consumption. 

Communication and control
The module communicates via CAN bus with the main controller for parameter configuration, telemetry, and state control. CAN interface: 125 kbps, 5 V level. Addressing and local configuration via digital screen and keys.

Key features

• Low-noise operation
• High peak efficiency (≥96.5%)
• High power density and ultra-wide constant-power output range
• Fan cooling; standby power <6W
• Comprehensive protections: over/under voltage, short-circuit self-rollback
