The CTS2000 series is an integrated automotive-grade DC-DC converter that steps high-voltage battery power down to 14V, 27.5V, 54V, or 80V for vehicle low-voltage systems. Full isolation, CAN + Bootloader, bottom cooling for IP67, and up to 8-unit parallel operation.
The CTS2000 is a board-level integrated DC-DC converter that takes high-voltage DC from the traction battery (144V up to 1000V) and produces a regulated low-voltage DC output for the vehicle's 12V/24V/48V electrical system, auxiliary heaters, or upper-body equipment.
A full isolation barrier separates the HV input from the LV output, protecting both the traction battery and the low-voltage electronics. The digital control loop uses soft-switching topology for high efficiency and low EMI across the load range.
A key differentiator is the built-in master-slave parallel logic: up to eight units can be paralleled without external controllers, enabling higher-current LV rails (e.g., 14V at 179A per unit, scalable to over 1400A) for heavy commercial vehicles and special equipment.
Every feature is designed around one job: safely and efficiently stepping traction-battery voltage down to the vehicle's low-voltage rail.
Automotive Modular Design
Board-level integrated construction with automotive-grade PCB layout and vibration-resistant mechanical assembly.
Full HV/LV Isolation
Galvanic isolation between traction battery input and low-voltage output protects vehicle electronics and meets safety standards.
Digital Soft-Switching Control
Full-digital control loop with soft-switching topology delivers high efficiency and low EMI across the entire load curve.
CAN + Bootloader
CAN communication with VCU/BMS, plus Bootloader-based firmware updates and field-tunable voltage/current parameters.
Bottom Cooling & IP67
Direct bottom-plate cooling enables a fully sealed IP67 assembly for under-chassis and battery-box mounting.
8-Unit Parallel Capable
Built-in master-slave logic allows up to eight units to parallel without external controllers for high-current LV rails.
Choose the rated input matching your battery pack and the output voltage matching your low-voltage system (14V for 12V vehicles, 27.5V for 24V trucks, 54V/80V for 48V/80V architectures).
