At the heart of electronic devices, the power supply serves as not just a source of driving force but also a cornerstone of stability and reliability. In particularly challenging outdoor environments with high temperatures, heavy rainfall, foreign object intrusion, and even lightning strikes, selecting an outstanding waterproof power supply becomes crucial to ensuring the continuous and efficient operation of electronic products. Mibbo MFS Series Constant Voltage Water-proof Power Supply boasts multiple layers of protection, effortlessly tackling these harsh conditions.

1. Conquering Rainstorms and High Humidity with Ease

Outdoor lighting projects often demand resilience in diverse settings such as city roads, park plazas, and building rooftops, where external factors like precipitation and humidity pose significant challenges. With the intensification of heavy rainfall nationwide due to the northward shift of the western Pacific subtropical high over the Huang-Huai region since early July, safeguarding the power supply of outdoor lighting projects has become increasingly important. The Mibbo MFS Series Waterproof Power Supply incorporates water-proof measures into every corner of its design, achieving an IP67 rating. Its exceptional waterproof construction utilizes advanced sealing technology and top-tier waterproof materials, allowing it to withstand the fierce onslaught of storms and torrential rains without flinching.

One-Piece Quadrant Enclosure: The MFS Series abandons the traditional two-piece (upper and lower cover) design, opting for a one-piece molding process with four large components. This innovation eliminates potential water seepage through seams, enhancing the overall waterproof and protective capabilities of the product.

Sealed Silicone Gasket: Embedded with a durable silicone gasket that resists temperature, wear, pressure, and oil, it ensures a tight seal, ensuring long-term reliability.

Waterproof Cable Treatment: Special craftsmanship ensures that cables are fully waterproof, guaranteeing the long-term stable operation of outdoor lighting projects.

PCBA Fully Potted with Encapsulant: A unique encapsulant seals and fills the interior of the power supply, effectively blocking moisture, salt fog, and acid rain, withstanding extreme weather conditions like rainstorms, snow, and hail.

2. Invincible Against Dust and Foreign Object Intrusion

Beyond defending against natural dust accumulation and rainwater, the MFS Series must also contend with phototactic insects that tend to swarm around light sources at night. Thus, the power supply's design incorporates superior sealing to ensure uninterrupted and safe operation.

Crafted from premium aluminum, the MFS Series boasts a fully sealed enclosure that keeps out dust, insects, and other foreign objects.

3. Triumphing Over the Challenge of High Temperatures and Sun Exposure

During operation, power supplies generate heat, which must be dissipated efficiently in open-air environments exposed to direct sunlight, prolonged summer heat, and intense UV radiation. Therefore, achieving both watertightness and effective heat dissipation becomes a critical research focus.

The interior encapsulant of the MFS Series possesses excellent thermal conductivity, swiftly transferring heat generated by the power supply to the exterior. Coupled with a high-thermal-conductivity, all-aluminum shell, it rapidly dissipates heat. With an operating temperature range of -40°C to 70°C and 100% full-load high-temperature aging tests during production, the MFS Series faces the scorching sun with ease.

4. Standing Firm Against Lightning Strikes and Overvoltage

While overvoltage, overload, and overcurrent protection are standard functions of any power supply, safeguarding against lightning strikes—a common threat in outdoor environments—necessitates a more robust solution. The MFS Series incorporates five layers of protection to secure electrical safety.

Lightning Protection: An embedded surge protection module confronts power line surges head-on, diverting or absorbing surge energy to minimize threats to other operational circuits.

Overvoltage Protection: An overvoltage lockout mechanism promptly cuts power or reduces voltage, preventing equipment damage under overvoltage conditions.

Overload Protection: By periodically limiting current during overload conditions, it minimizes system downtime caused by protective measures.

Short-Circuit Protection: Designed to withstand long-term short circuits without damage, it automatically recovers upon short-circuit removal. It swiftly cuts power during short circuits, protecting both loads and the power supply from high current surges.

Overcurrent Protection: Provides adequate safety during power supply, safeguarding both the device under test and the testing equipment from accidental damage.

5. Efficient, Reliable, and Stable

Equipped with an active PFC function, the MFS Series Waterproof Power Supply boasts a high PF value, stability, and reliability, significantly enhancing power conversion efficiency up to 91%. With a 3.75KV withstand voltage insulation impedance, it operates safely and securely.

 

Efficient, reliable, and unfazed by the quadruple challenges of the outdoors, the Mibbo MFS Series C-V Water-proof Power Supply is tailored for applications in rainy or humid environments, making it the ideal choice for outdoor lighting scenarios such as bridges, roads, parks, and buildings.
