Engineered For High Reliability
Precision Switching & High-Voltage SMPS Modules
Explore our core industrial switching modules optimized for process automation, infrastructure lighting, high-voltage test racks, and telecommunications installations.
Deploying high-voltage and high-current power supply architecture in mountainous regions like Encamp requires overcoming severe physical challenges, including reduced dielectric breakdown voltage and extreme thermal fluctuations.
Hydroelectric & Alpine Grid Substations
With regional energy production heavily integrated into Pyrenean hydroelectric cascades, secondary auxiliary systems require ultra-low ripple DC supplies capable of withstanding switching transient surges and cold-start conditions down to -25°C.
Ski Lift Automation & Gondola Telemetry
Serving high-altitude transit lines like the Funicamp, our enclosed and DIN rail systems provide uninterrupted 24V/48V bus power to PLCs, optical safety barriers, and emergency cable monitoring sensors under severe continuous mechanical vibration.
Resilient Telecom & Data Relays
High-altitude ridges demand power units with enlarged clearance and creepage distances. Our isolated power supplies guard sensitive microwave uplinks and optical transceivers against atmospheric lightning strikes and inductive discharge.

High Altitude Power Derating: Paschen's Law & Thermal Dissipation in Encamp
Operating switching power units at altitudes above 1,300 meters requires engineering foresight. Lower air density impacts both dielectric withstand capability and natural convection cooling.

1. Dielectric Clearance Multipliers
As atmospheric pressure drops, the breakdown voltage of air diminishes according to Paschen's Law. Harlon’s export designs incorporate primary-to-secondary spacing exceeding 8.0 mm, guaranteeing full insulation integrity even in high-mountain Encamp installations.
2. Forced Air vs. Convection Cooling
With less dense air mass per cubic meter, heat removal efficiency drops by approximately 10% per 1,000 meters. Our engineering team incorporates oversized aluminum heat spreaders and intelligent thermal-throttled ball-bearing cooling fans to prevent hot-spot formation.
3. Extreme Condensation Protection
Mountain microclimates cause severe thermal cycling between sunny daytime peaks and sub-zero nights. Our waterproof and potted SMPS lines prevent micro-condensation droplets on high-voltage copper traces, preventing flashovers.

Procurement Clarity
Frequently Asked Questions by Encamp Buyers
Key information regarding international logistics, mountain-grade environmental protections, customs documentation, and commercial procurement terms.
What is the typical shipping lead time and customs route for Encamp?
Consignments bound for Encamp are routed via European hubs such as Barcelona or Toulouse, followed by direct bonded freight into Andorra. Express air sample delivery typically takes 4–7 business days, while volume sea-freight orders arrive within 25–35 days with full export documentation.
Are Harlon power supplies certified for European CE and RoHS standards?
Yes. All export units comply with CE Low Voltage Directive (LVD) and Electromagnetic Compatibility (EMC) regulations, as well as RoHS hazardous substance restrictions. Full laboratory test reports and declarations of conformity are provided with each production batch.
How do you handle grid voltage fluctuations common in alpine areas?
Our power supplies incorporate ultra-wide AC input stages (85V–264VAC universal input) along with integrated varistors and surge arresters. This architecture absorbs utility grid voltage transients caused by heavy alpine machinery or lightning surges without dropping output regulation.
Can we request custom DC output voltages, such as 36V or 48V for telecom?
Absolutely. Beyond our standard 5V, 12V, 24V, 36V, and 48V configurations, our engineering team regularly designs customized step-up or step-down converters with specific potentiometer trim ranges, redundant parallel current-sharing diodes, and remote ON/OFF control.
What is the minimum order quantity (MOQ) for custom-labeled supplies?
Standard catalog products require low MOQs, and small sample runs can be shipped immediately from stock. For buyer-branded private labeling, customized silk-screened metal chassis, and tailored packaging, our flexible production lines accommodate batches starting from 200–500 units.
What international payment and commercial trade terms are accepted?
We support flexible Incoterms including FOB Ningbo/Shanghai, CIF, CFR, EXW, and DDU. Accepted payment methods encompass T/T wire transfer, L/C at sight, credit card, PayPal, and secure escrow arrangements in major trading currencies (EUR, USD, GBP, CNY).
