CTS 1kW 1.2kW Isolated DC-DC Converter Modules for Light EVs
The CTS2010 is a compact automotive-grade DC-DC converter stepping battery voltage (48V up to 700V) down to 14V, 27.5V, or 48V for the vehicle's low-voltage system. Full isolation, CAN + Bootloader, IP67 bottom cooling

Small Enough for Light EVs. Tough Enough for Commercial Duty.
The CTS2010 is the lower-power member of our integrated DC-DC family. At just 1.0–1.2kW and 170×100×50mm, it is designed for vehicles where every millimeter and gram counts — from 48V light EV platforms to 540V commercial trucks needing a compact auxiliary DC-DC.
Despite its small size, it shares the same automotive-grade DNA as the larger CTS2000: full isolation between input and output, full-digital soft-switching control, hardware + software dual protection, and CAN communication with Bootloader support.
Like its larger sibling, up to eight units can be paralleled in master-slave mode without external controllers, making the CTS2010 scalable from a single 14V/72A rail to multi-hundred-amp LV systems for special vehicles and marine applications.
Compact Power, Full Automotive Capability
Everything you expect from a vehicle-grade DC-DC, in a housing that fits where larger units cannot.
Automotive Modular Design
Board-level integrated construction with automotive-grade PCB layout and compact, vibration-resistant mechanical assembly.
Full HV/LV Isolation
Galvanic isolation between 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 load range.
Dual-Layer Protection
Comprehensive hardware + software protection for overvoltage, overcurrent, overtemperature, and short-circuit faults.
CAN + Bootloader
CAN communication with VCU/BMS, plus Bootloader-based firmware updates and field-tunable voltage/current parameters.
8-Unit Parallel Capable
Built-in master-slave logic allows up to eight units to parallel without external controllers for higher-current LV rails.
11 Models from 48V to 700V Battery Packs
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, 48V for mild-hybrid auxiliary rails).

170×100×50mm. The Compact Choice.
The small footprint and 50mm profile let the CTS2010 mount in tight spaces where larger DC-DC units will not fit — ideal for light EVs, two-wheelers, and upper-body equipment.
