Standardized, ultra-compact, and ruggedized power modules optimized for 1.5kV DC catenary networks, 110V/72V/48V onboard passenger train infrastructure, and municipal tram platforms in the Netherlands.
The Netherlands possesses one of the most densely utilized rail networks in the world, managed by ProRail and operated by key carriers such as NS (Nederlandse Spoorwegen), Arriva Netherlands, Keolis, and Transdev. With the unique operating conditions of the Dutch rail environment—ranging from the standard 1.5 kV DC electrification line across main corridors to the 25 kV AC 50 Hz high-speed line (HSL-Zuid) and the dedicated Betuweroute freight line—onboard power conversion systems require extreme reliability, compact footprints, and high surge endurance.
As premier suppliers and exporters of railway transportation power converters, NetPower delivers standard brick topologies, micro-power modules, and custom high-voltage DC-DC converters designed specifically to thrive under local Dutch technical and environmental demands.
Delivering isolated 110V DC auxiliary power supply modules for train control systems (TCMS), door control mechanisms, passenger infotainment screens, and seat-side 230V AC inverter pre-regulators across Dutch Intercity fleets.
Supplying high-density encapsulated DC-DC converters for urban light rail in Amsterdam (GVB), Rotterdam (RET), and The Hague (HTM). Built to handle constant start-stop cycles, mechanical vibrations, and 600V/750V catenary surges.
Providing custom bidirectional DC-DC converters and IP67 on-board battery chargers (OBC) for regional zero-emission trains operating in Groningen, Friesland, and Gelderland, supporting rapid energy transfer between traction batteries and fuel cells.
Technical Insight for Dutch Engineers: In Holland's coastal climate, salt spray and high humidity (up to 95% RH along the North Sea corridors) pose severe risks of dielectric breakdown. All NetPower railway-grade modules feature silicone potting and conformally coated PCBs meeting EN 45545-2 fire safety guidelines and IP67 ingress standards.
The Dutch rail sector is undergoing significant modernization driven by national sustainability targets, digital signal transitions, and grid capacity expansion. Power converter architectures must evolve to meet these systemic shifts:
ProRail and NS are actively evaluating the migration of the Dutch DC catenary voltage from 1.5 kV to 3 kV DC to handle higher train density and cut resistive line losses. NetPower wide-input DC-DC converters accommodate wide voltage dynamics (up to 160V DC input logic and 400V-650V auxiliary DC buses) with seamless tolerance to harmonic ripple and transient spikes.
The nationwide deployment of the European Rail Traffic Management System (ERTMS Level 2/3) across the Netherlands requires uninterruptible power supply (UPS) modules for onboard European Train Control System (ETCS) computers. NetPower isolated bricks provide ultra-clean output rails with sub-1% ripple, suppressing EMI per EN 50121-3-2 standards.
Non-electrified regional lines in the eastern and northern provinces are shifting to battery-electric hybrid trains. High-efficiency 3.3kW and 5kW DC-DC modules allow precise energy management between auxiliary battery banks, regenerative breaking systems, and onboard low-voltage 24V/48V control buses.
Every railway power module exported to the Netherlands must rigorously satisfy European standards. Below is an engineering overview of NetPower converter compliance metrics:
| EN Standard Requirement | Standard Specification Parameter | NetPower Converter Performance | Engineering Benefit |
|---|---|---|---|
| EN 50155 Input Voltage Range | 0.7 Un to 1.25 Un (Continual), 0.6 Un to 1.4 Un (Flucs) | Ultra-wide 4:1 & 10:1 Input Ranges (16V to 160V DC) | Covers 24V, 48V, 72V, 96V, and 110V nominal battery buses without dropouts. |
| EN 50155 Interruptions (Class S2/C2) | 10 ms interruption hold-up time capability | Integrated active hold-up control circuit support | Prevents TCMS micro-processor resets during dynamic pantograph bounces. |
| EN 61373 Shock & Vibration | Category 1, Class A & B Body/Underfloor Mounted | Encapsulated potted bricks with ruggedized pins | Survives continuous mechanical stress on heavy freight and high-speed rail. |
| EN 45545-2 Fire Safety | Hazard Level HL1 to HL3 compliance | Low Smoke Zero Halogen (LSZH) potting compounds | Permitted for under-seat and roof installation in high-density passenger cars. |
| EN 50121-3-2 EMC Limits | Conducted & Radiated Electromagnetic Emission | Internal Pi-filters & low-noise switching topology | Zero interference with sensitive axle counters, GSM-R, and ETCS radio balises. |
NetPower Technologies is a global leader in high-efficiency, high-power-density board-mounted isolated DC-DC converters, non-isolated point-of-load (POL) regulators, and vehicle-grade e-Mobility power conversion platforms. Decades of specialized switch-mode design expertise allow us to support demanding railway applications across Europe and worldwide.
From micro-power modules below 15W up to 1000W+ bricks (1/32nd, 1/16th, 1/8th, quarter, half, and full brick standard DOSA footprints) to 5kW liquid-cooled vehicle-grade converters, enabling designers to scale a single architecture across their entire product line.
Every platform undergoes upfront thermal simulation, worst-case loop stability analysis, HALT/HASS (Highly Accelerated Life Testing / Stress Screening), and 100% automated final electrical testing. This ensures continuous operation under ambient temperatures from -40°C up to +85°C.
We modify mechanical housings, pinouts, cooling strategies (conduction, air, liquid), and firmware for CAN communications to match exact Dutch rolling stock procurement specs, maintaining low NRE costs and rapid time-to-market.

Inquire Now & Request Engineering SupportNetPower isolated DC-DC railway converters support all standard nominal onboard voltages used by NS and regional operators, including 24V, 48V, 72V, 96V, and 110V DC. Our 10:1 dynamic input range modules (e.g., 16V-160V DC continuous) allow one converter part number to be standardized across multiple train fleets.
Yes. Our modules feature dedicated pins for external hold-up capacitor integration, ensuring full compliance with EN 50155 Class S2 (10 ms interrupt) and Class C2 (full performance during brief catenary interruptions), preventing reboot cycles on passenger Wi-Fi and TCMS nodes.
The Netherlands experiences high salt moisture airborne along coastal regions like Zeeland, South Holland, and North Holland. NetPower encapsulated DC-DC bricks use IP67 vacuum silicone potting, providing total insulation against moisture ingress, salt haze corrosion, and mechanical shock.
Absolutely. We specialize in form-, fit-, and function-compatible replacements for legacy board-mounted DC-DC bricks. Our standard DOSA footprints (Quarter Brick, Half Brick, Full Brick) allow straightforward drop-in replacements for aging onboard electronics during mid-life train overhauls.
Each converter sample ships with complete engineering documentation, including released datasheets, thermal derating curves, EMI filter recommendations for EN 50121-3-2 compliance, and MTBF calculation reports per Telcordia SR-332 / MIL-HDBK-217F.
