Precision-manufactured in our ISO 9001 certified plant. Every unit features 100% full-load burn-in testing, universal AC input, comprehensive overload and surge protections, and rigorous CE & RoHS certifications tailored for Romanian importers and systems integrators.
In-depth power electronic design considerations: harmonic suppression, thermal derating margins, low no-load consumption, and galvanic isolation engineered to satisfy stringent European Union norms.
Romanian industrial grids, especially in developing logistics belts outside Bucharest (Sectorul Agricol Ilfov, CTPark, WDP parks), can experience transient spikes and voltage drops. Our LRS series incorporates a robust input stage featuring heavy-duty Metal Oxide Varistors (MOVs) and an NTC inrush current limiter capable of withstanding 300VAC surge inputs for 5 seconds without degradation, compliant with EN 61000-4-5 (Line-to-Line 2kV, Line-to-Earth 4kV).
Standardized at a strict 30mm chassis profile, the LRS series is designed for 1U rack installations and cramped industrial control panels. The internal architecture utilizes planar magnetics concepts and direct chassis thermal dissipation via a thermally conductive silicone pad. This enables high operational efficiency up to 91.5% and natural convection cooling up to 200W without requiring forced-air fans, eliminating mechanical acoustic noise and fan failure risks.
Full compliance with European Commission Regulation (EU) 2019/1782 and Directive 2009/125/EC. The LRS control IC features green-mode burst operation under light-load conditions, keeping no-load power consumption strictly below 0.2W to 0.75W across the range. For automated warehouses and intelligent commercial building systems running continuous standby cycles across Bucharest, this delivers measurable cumulative energy savings.

Bucharest and its surrounding metropolitan zone represent Romania's dense core of automated logistics, smart infrastructure, and manufacturing modernization. Here is how Harlon LRS power supplies integrate into the regional hardware ecosystem.
Massive fulfillment centers clustered in Chiajna, Dragomirești-Vale, and Otopeni rely heavily on automated roller conveyors, optical barcode sorters, and pick-to-light picking modules. Our 24V DC LRS-150 and LRS-350 power supplies deliver stable, low-noise rails for field sensors, photoelectric barriers, and terminal microcontrollers under continuous 24/7 duty cycles.
From shopping hubs like Băneasa Shopping City and AFI Cotroceni to modern corporate towers in Floreasca-Barbu Văcărescu, commercial facades demand ultra-compact constant voltage drivers. The 30mm height profile of the LRS series allows seamless integration within slim lightboxes, channel letters, and architectural coves where thermal clearance is minimal.
Bucharest is Eastern Europe's premier telecommunications node. In telecom colocation sites and edge networking points across Sector 2 and Pipera, LRS 48V DC modules serve as auxiliary and telemetry control power supplies for fiber distribution frames, monitoring equipment, and smart PDU units requiring rigorous MTBF benchmarks.
Under Bucharest Municipality green mobility incentives, the rollout of AC Level 2 and DC fast-charging points is accelerating across public parking decks and transit stations. Our enclosed LRS and DIN rail units deliver robust 12V and 24V auxiliary power to OCPP communication controllers, RFID payment modules, and contactor coils.
Situated within the Pitești-Bucharest industrial automotive corridor, subcontract manufacturing workshops demand high-reliability power units for CNC machinery panels, automated screwdriving heads, and PLC enclosures. The high temperature tolerance (-30°C to +70°C) of the LRS units guarantees stable operation under heavy industrial shop-floor environments.
Bucharest’s medical research facilities and private clinical networks utilize diagnostic automation and centrifuge systems requiring low EMI interference. Our units satisfy EN 55032 Class B conducted emission standards, preventing cross-talk and high-frequency noise interference with sensitive analytical sensors.
Macroeconomic and technical market dynamics driving procurement shifts for power supplies across the Romanian B2B landscape.
Romania’s National Recovery and Resilience Plan (PNRR) has earmarked billions of euros for the digital transformation of industrial enterprises and municipal energy grids. This funding accelerates the replacement of legacy, bulky linear transformers with compact, high-efficiency enclosed switching power supplies that comply with current Ecodesign guidelines.
Multinational manufacturers are shifting production lines from Central Europe into Romania to optimize production costs while retaining single-market access. Local electrical panel builders in Bucharest require certified, modular SMPS components that can be immediately shipped, custom-labeled, and pre-configured for DIN rail or chassis mounting.
