Catalog Recommendation
Industrial-Grade Power Supply & Battery Backup Conversion Modules
Tested under rigorous full-load high-temperature conditions to provide continuous uninterruptible operation across telecommunications, healthcare facilities, cold storage, and decentralized solar mini-grids in Cuba.
Localized Application Scenarios Across Cuba's Critical Infrastructure
From Havana to Santiago de Cuba, public infrastructure and foreign-capital enterprises require resilient power electronics capable of handling frequent grid interruptions (apagones) and aggressive marine humidity.
Medical Facilities & Biotech Clinics
Hospitals, regional polyclinics, and CIGB (Center for Genetic Engineering and Biotechnology) facilities utilize 24V and 48V DC power supplies linked with buffer batteries to keep diagnostic incubators, vaccine cooling units, and monitoring systems running during blackout switchovers.
ETECSA Telecom & Transmission Hubs
Cellular towers, optical distribution nodes, and public Wi-Fi access parks depend on 48V DC 1200W high-amperage power modules. Dual AC input capabilities (85V–264V) accommodate severe brownouts without tripping line breakers or dropping cellular backhauls.
Varadero & Cayos Resort Tourism
International resort enclaves manage standalone generator sets and reverse osmosis desalinators. Our conformal-coated SMPS and LED drivers resist high salinity, sulfurous coastal winds, and high ambient temperatures inside unconditioned control boxes.
Decentralized Solar & Microgrid Storage
With UNE expanding distributed photovoltaic generation across rural agricultural hubs, AC-to-DC rectifiers and DC-DC converters manage LiFePO4 and lead-carbon bank charging, maintaining auxiliary PLC logic control for continuous solar tracking and pump operation.

Cuba Power Grid Reliability Dynamics: Why Engineering Resilience Dictates Supplier Success
Cuba's electric infrastructure (SEN - Sistema Eléctrico Nacional) faces unique supply constraints, aging thermoelectric generators (such as Guiteras and Felton), and reliance on imported fuel oil. This structural reality has shifted procurement requirements from generic low-cost switching units to ultra-wide input, high thermal-margin battery backup platforms.
1. Wide-Voltage Slew Rate Tolerance
Standard power supplies calibrated strictly for 110V ±10% fail rapidly in Cuban municipalities where utility lines collapse to 85VAC during peak evening load and spike to 260VAC following sudden grid re-energization. Chinese manufacturers providing wide 85V–264VAC automatic ranging with internal MOV transient surge suppressors prevent field burnout.
2. LiFePO4 Transition in Tropical Climates
Traditional flooded and AGM batteries deteriorate rapidly in 35°C–40°C Cuban ambient conditions. Industrial importers are standardizing on smart switching power supplies with adjustable float, CC/CV output curves, and temperature compensation tailored for Lithium Iron Phosphate chemistries.
3. Salt Fog & High Humidity Anti-Corrosion
Operating within 5 kilometers of the Caribbean shoreline exposes power circuit traces to rapid dendrite growth and galvanic oxidation. Industrial buyers mandate conformal PCB coating (silicone or polyurethane dip) and nickel-plated brass terminals to guarantee a 5-to-10 year operating life.

Procurement FAQ
Frequently Asked Questions by Importers & Engineers in Cuba
Essential regulatory, technical, and trade guidance for Cuban state enterprises (importadoras), joint ventures (empresas mixtas), and MIPYMES sourcing Chinese power electronics.
How do Harlon switching power supplies handle extreme Cuban voltage fluctuations (85V–265V)?
Our power supplies incorporate universal wide-input topologies (85–264VAC universal input or 115V/230V auto-sensing manual override). In conjunction with oversized primary bulk capacitors rated for 105°C and up to 400V–450V surge limits, the power supplies deliver an extended hold-up time (>20ms). This enables uninterrupted operation through severe voltage dips, momentary sag events, and utility generator transfer latency typical across Cuban municipal circuits.
What protection mechanisms exist against coastal Caribbean salt air and mold growth?
For equipment destined for coastal installations (such as Mariel Special Development Zone, Varadero hotel corridors, and Havana harbor facilities), Harlon provides optional 3-proof conformal coating (anti-salt, anti-humidity, anti-fungus) across both sides of the printed circuit board assembly. Additionally, we use passivated aluminum alloy housings, stainless steel retention screws, and corrosion-resistant terminal blocks to prevent oxidation caused by salt spray.
Can Harlon power modules be used directly as battery chargers for lead-acid and LiFePO4 banks?
Yes. Models like our S-1200-48 and adjustable S-145 series feature output voltage potentiometers and constant-current (CC) limiting circuitry. When configured with external blocking diodes or integrated dual-mode charging modules, they provide optimal bulk, absorption, and float voltage levels for 12V, 24V, 36V, and 48V battery systems, preventing overcharge while delivering maximum replenishment speed after power is restored.
What international trade documents, export certifications, and shipping terms do you support?
Harlon holds ISO 9001 certification and on-site supplier verification by SGS. Our catalog models carry CE, RoHS, and FCC conformity reports. For Cuban import documentation, we support full consular legalization, Certificates of Origin (Form A/General), packing lists, maritime bill of lading (B/L) processing for shipping lines delivering into Port of Mariel (ZEDM), as well as air freight via José Martí International Airport (HAV). We operate under FOB, CFR, CIF, and EXW terms.
How does Harlon support private labeling and custom voltage/current specifications?
With 18 years of OEM/ODM experience and an in-house engineering team, we provide comprehensive OEM customization. This includes custom DC voltages (e.g., 13.8V float for telecommunications, 27.6V for fire alarms, 54.4V for lithium packs), extended operating temperature components (-40°C to +70°C), buyer-specific silkscreen branding, customized packaging cartons, and specific connector wire harnesses.
