Product Overview
Bring Charging and Auxiliary Power into One Assembly
The CTS3000 integrated on-board charger and DC-DC converter brings two power-conversion functions into a single module. The OBC provides high-voltage battery charging, while the DC-DC converter provides a 14V output for low-voltage vehicle systems.
Its modular, board-level architecture supports compact power-system packaging for electric vehicles, mobile machinery and other battery-powered platforms. Select the model that matches your battery voltage range and auxiliary power requirements.
Product Features
Designed for System Integration
Fully Digital Soft Switching
Fully digital control and soft-switching technology support controlled power conversion across the module’s power functions.
Active PFC
Active power factor correction and a 90–290VAC input range support integration across different AC supply conditions.
Hardware and Software Protection
Protection at both hardware and software levels supports operation within the specified application conditions.
Bootloader and Parameter Adjustment
Supporting software provides bootloader functionality and parameter adjustment for commissioning and firmware maintenance. CC/CP interface and wake-up handling are also supported.
Baseplate Heat Dissipation
Bottom heat dissipation supports thermal integration. The module supports IP67 assembly design, subject to the final enclosure, sealing and installation.

Contact Technical Sales →What does the CTS3000 2-in-1 module integrate?
It combines a 3.3kW on-board charger and a DC-DC converter in one module. The DC-DC section provides 14V output at a listed 1.8kW or 1.2kW, depending on model.
What AC input voltage does it support?
The specified AC input range is 90–290VAC. Contact CTS to confirm available charging power under your intended input conditions.
Which high-voltage output ranges are available?
The series offers 40–80VDC, 50–100VDC, 80–140VDC, 100–180VDC and 250–450VDC output ranges. Each range corresponds to a different model.
Do all models include a 1.8kW DC-DC converter?
No. CTS3002-01, CTS3003-01 and CTS3004-01 have a listed 1.8kW DC-DC output. CTS3005-01 and CTS3006-01 have a listed 1.2kW DC-DC output.
Is the module IP67-rated?
The specification describes a bottom heat-dissipation design that supports an IP67 assembly. The final ingress-protection rating depends on the complete enclosure, connectors, sealing and installation and should be confirmed for the finished assembly.
Does it support firmware and parameter adjustment?
Yes. The specification lists supporting software with bootloader functionality and parameter adjustment.
