High-efficiency AC/DC switching power supplies, isolated DC/DC converters, and DIN-rail systems customized for transit cabinets, rolling stock, and industrial automation across Indonesia.
Analyzing electrical conversion requirements, EN 50155 compliance, tropical thermal derating, and grid stability for OEM manufacturers and public transit operators across the Indonesian archipelago.
The Indonesian electrical grid (PLN) frequently experiences ambient brownouts, surge transients, and harmonics—especially in industrial corridors such as Cikarang, Karawang, and Surabaya. Our railway-grade switching power supplies incorporate active PFC (Power Factor Correction >0.98), input surge withstand up to 300VAC for 5 seconds, and galvanic isolation ratings from 1500VDC to 6000VDC to shield sensitive microprocessors, signaling interlocks, and passenger information systems from catastrophic failure.
Rolling stock equipment installed in PT KAI locomotives, electric multiple units (EMUs), and urban tramlines requires rigorous certification. Our railway power supply manufacturing lines adhere strictly to EN 50155 (Electronic Equipment Used on Rolling Stock) for input voltage range limits (0.7 to 1.25 Vin nominal with 1.4 Vin transients), as well as EN 45545-2 fire and smoke toxicity standards, ensuring maximum passenger safety in underground and elevated transit networks.

Engineered to thrive in Indonesia's tropical climate, high-humidity corridors, and demanding public transportation networks.
In modern driverless systems like the LRT Jabodebek and MRT Jakarta, zero-loss communication between onboard Automatic Train Control (ATC) units and trackside balises is non-negotiable. Our isolated railway DC/DC converters provide continuous power to Communication-Based Train Control (CBTC) units, eliminating ground loop interference and protecting microcontrollers against supply rail voltage dips during pantograph bounce.
PT KAI commuter lines operating in the Jabodetabek area require robust 24VDC and 12VDC power conversion to run digital LED/LCD route displays, public address speakers, and high-definition IP security cameras. Our 12V 2A desktop adapters and modular chassis converters feature MTBF exceeding 500,000 hours, keeping passenger transit systems fully operational under continuous 24/7 duty cycles.
Across Java and Sumatra, railway crossings are exposed to extreme ambient heat and monsoon downpours. Our ultra-compact DIN-rail power supplies (such as the NDR-480-24 and slim 60W-240W series) fit inside sealed IP66 trackside cabinets, delivering regulated DC power to motorized barrier gates, warning bells, and optical signal lights without thermal shutdown.
Beyond transportation, Indonesia’s booming industrial sectors in Riau, North Sumatra, and West Java depend on heavy-duty enclosed SMPS units for programmable logic controllers (PLCs), motor drives, and conveyor networks. Featuring active PFC and adjustable output voltages (0–200V DC), our power units handle heavy inductive loads and line transients common in palm oil mills and mining logistics facilities.
Understanding the macro-economic drivers shaping power conversion technology procurement across the Southeast Asian industrial leader.
With ongoing planning for the Jakarta-Surabaya high-speed rail extension and freight rail projects connecting Kalimantan coal and nickel mining basins to coastal ports, demand for certified EN 50155 DC/DC converters (72V, 110V nominal battery inputs) is projected to grow by 14.2% annually through 2030.
Indonesia’s commitment to net-zero emissions has accelerated the transition toward electric buses (TransJakarta) and automated light rail. Auxiliary power conversion systems must balance ultra-high efficiency (>94%) with low standby power draw to maximize battery range and reduce fleet operational expenditure.
PLN’s ongoing grid modernization initiatives require SCADA telemetry units, digital protection relays, and smart meters powered by wide-input AC/DC power supplies capable of handling severe input voltage sags and 4kV lightning surges common during equatorial tropical storms.
As a dedicated railway power supply manufacturer, we combine decades of technical innovation with flexible low-volume, high-mix manufacturing tailored to OEM project requirements.
Avoid expensive ground-up custom redesigns. We modify existing qualified standard platforms—adjusting pinouts, output trim voltages, conformal coating types, and mechanical mounting brackets—to match your exact mechanical space constraints while preserving core safety certifications.
Every single railway and industrial power unit undergoes automated 100% high-temperature full-load burn-in screening prior to shipment. This process eliminates early component mortality and guarantees field reliability under Indonesia's demanding tropical ambient conditions.
Our senior field application engineers (FAEs) assist Indonesian design teams with schematic reviews, EMC filter design recommendations, thermal simulation analysis, and localized qualification documentation for seamless project sign-off.
Clear, expert answers to key technical, regulatory, and logistics queries from local systems integrators and contractors.
Our industrial and railway power supplies are available with optional or standard conformal coating (IPC-CC-830B compliant polyurethane or acrylic resin). This protects internal PCB surface-mount components, transformer windings, and solder joints against moisture condensation, airborne salt spray, and fungal growth in humid coastal climates like Jakarta, Semarang, and Surabaya.
We provide ultra-wide DC input converters covering standard railway nominal voltages: 24VDC, 48VDC, 72VDC, and 110VDC. Our 4:1 and 12:1 wide-input series accommodate the full EN 50155 continuous range (0.7 to 1.25 Vin) and brownout transients down to 14.4VDC or surges up to 154VDC without interrupting nominal output regulation.
Yes. Our power conversion modules carry international safety approvals including IEC/EN/UL 62368-1 for IT and industrial equipment, IEC/EN 60601-1 (2xMOPP) for medical gear, and EN 50155 / EN 45545-2 for rolling stock. Full CB test certificates and UL file numbers are provided to assist local contractors with Indonesian SNI compliance filings.
Absolutely. Through our Modified Standard Program, we can customize output voltages (e.g., trimming a 24V supply to 27.6V for battery charging), fit customized terminal blocks or M12 circular railway connectors, and pre-adjust current limit thresholds to match your exact system specifications with low minimum order quantities (MOQs).
Standard catalogue items are maintained in buffer stock for fast dispatch within 3–5 business days. For customized OEM production runs, factory lead times typically range between 4 to 6 weeks. Express air freight to Soekarno-Hatta International Airport (CGK) or sea freight to Tanjung Priok / Tanjung Perak ports can be coordinated with full export documentation.
