Explore our engineering line-up designed for high ambient temperatures, wide input voltage swings, and continuous operation in demanding fleet & industrial applications.
Industrial fleets, electric buses, and commercial haulage platforms operating across Northern India, Gujarat, and the southern industrial belts encounter ambient temperatures ranging from 45°C to 50°C during summer peak months. Standard forced-air cooled DC/DC converters fail prematurely due to dust accumulation, monsoon moisture ingress, and thermal derating.
Contact cooling (conduction cooling via a precision-machined aluminum cold plate or vehicle chassis frame) eliminates internal fans. By conducting thermal dissipation directly into external heat sinks or liquid coolant loops, converter junction temperatures remain stabilized even under continuous full-load output.
From high-capacity electric bus fleets under FAME initiatives to heavy rail electrification and decentralized microgrids, our DC/DC converters are optimized for Indian operational realities.
High-voltage battery buses running on 400V to 750V DC traction packs require ultra-reliable step-down conversion to 12V/24V to supply steering pumps, air braking compressors, telemetry, and interior lighting. Our DVCHx3 platform guarantees continuous galvanic isolation and zero thermal derating up to 85°C baseplate temperatures.
Indian rail networks demand power conversion components that survive wide input surge variances, severe mechanical shocks (IEC 61373 Class 1B), and high humidity. Our sealed contact-cooled converters step down overhead line voltage spikes to supply clean, regulated power for train control management systems (TCMS) and emergency backup batteries.
With rapid expansion of automated warehouse hubs across Pune, NCR, Bengaluru, and Chennai, Automated Guided Vehicles (AGVs) and electric forklifts require compact, flat-profile DC/DC converters embedded into slim aluminum frames. Contact cooling enables dust-tight chassis mounting without fan maintenance down-time.
Off-grid industrial sites and telecom towers across Tier-2 and Tier-3 Indian cities utilize direct DC coupling from solar PV banks to stationary battery energy storage systems (BESS). High-voltage contact-cooled converters efficiently regulate DC bus levels with over 96% efficiency under continuous duty cycles.
Heavy excavators, dumper trucks, and mining platforms operating in open-cast mines suffer from violent vibration and thick ambient particulates. Contact-cooled converters potted in IP69K sealed housings ensure reliable 24/7 power delivery to onboard control units, sensors, and GPS trackers.
A comprehensive side-by-side technical evaluation for Indian automotive OEMs, system integrators, and industrial procurement managers.

India is undergoing one of the world's most rapid transportation and industrial power transformations. Key policy directives and operational shifts are driving demand for ruggedized DC/DC power conversion:
Combining German power-electronics engineering pedigree with scalable manufacturing flexibility for custom and volume export orders.
Every converter family is designed with extensive testing against surge voltages, EMI/EMC compliance (EN 55011 / CISPR 25), and extreme thermal stress profiles, ensuring field stability across decades of service.
From automated SMT surface mounting and THT soldering to automated vacuum potting and thermal cycling, 100% of production processes are internally managed to prevent component failure.
Every single unit undergoes rigorous 100% full-load burn-in and automated safety testing using our proprietary DTS test software suite before shipment to international clients.
Whether you require custom mounting bracket profiles, specific connector types (Deutsch, Amphenol), or specialized CAN parameter configurations, our application engineers adapt series products for small and large volumes alike.
Dedicated export engineering services provide direct documentation for Indian customs clearance, BIS certification compliance, and expedited door-to-door air/sea delivery to major Indian ports.
Expert insights covering technical compatibility, environmental resilience, custom modification, and import protocols for the Indian market.
Contact-cooled converters rely on direct conductive heat transfer ($R_{\theta j-c}$) from internal heat-generating power MOSFETs/SiC devices to a flat aluminum baseplate. When mounted directly to an existing vehicle chassis frame, metal body plate, or external passive aluminum heatsink, heat energy dissipates over a massive thermal mass. This allows continuous full-power output without requiring an active liquid cooling pump or failure-prone mechanical fans.
Our DVCx3 series covers lower battery voltage ranges (24V, 48V, 96V, 110V DC), while our high-voltage DVCHx3 series operates across ultra-wide input windows from 200V up to 900V DC. This ensures full operational compatibility with standard 400V battery packs as well as next-generation 800V high-voltage commercial electric buses and heavy haulage vehicles across India.
Yes. The entire internal electronics assembly is encapsulated using high-grade, thermally conductive polyurethane compound inside an IP67 / IP69K sealed aluminum casting. This construction provides total immunity against fine conductive red dust, humidity, direct high-pressure water jets during vehicle washdowns, and total temporary water submersion during severe monsoon floods.
Absolutely. Parameterization of voltage limits, current thresholds, temperature status reports, and fault diagnosis codes can be customized directly at our factory to match your specific CAN 2.0B, SAE J1939, or CANopen communication profiles. This allows seamless plug-and-play integration into vehicle control units (VCUs) produced by Indian telemetry suppliers.
Yes. Because we control design, SMT PCB assembly, potting, and automated end-of-line testing under one roof, we flexibly support prototype series, pre-production trial runs, and medium-volume production runs with tailored lead times and full engineering support.
All exported units are supplied with comprehensive test certificates, CE compliance declarations, ISO 9001 quality audit reports, RoHS/REACH material documentation, and test reports according to international automotive standards (EN 60950-1, IEC 60068 for environmental stability, and ISO 16750 for mechanical vibration).
