Littelfuse, Inc., a leading global provider of circuit protection solutions, has recently launched the 514 Series ceramic tube fuse, a compact and fast-acting device rated for 500VAC with current ratings ranging from 1.6A to 12.5A. Designed for high-voltage AC power line protection in HVAC systems and industrial applications, these fuses can interrupt currents up to 5,000A at 500 volts AC. Their advanced design minimizes the impact of temperature fluctuations and mechanical vibrations, significantly enhancing reliability.
Measuring just 6.3mm in diameter by 32mm in length, the 514 Series allows engineers to save valuable board space while ensuring effective component protection. This makes it an excellent choice for modern, space-constrained designs. The fuse is particularly well-suited for energy-efficient and high-power applications in residential and commercial settings, such as HVAC systems, smart meters, uninterruptible power supplies (UPS), three-phase power supplies, and renewable energy systems.
Ben Zheng, Littelfuse’s global product manager, highlighted the unique combination of low current rating and high breaking capacity in such a small package: “The 514 Series offers exceptional overcurrent protection in extreme conditions, especially when used for short-circuit protection in AC output or inverter circuits.†He added that the fuse is ideal for applications requiring both precision and durability.
Key features of the 514 Series include:
- A high-rated AC voltage of 500V and a breaking capacity of 5,000A, making it suitable for AC circuits in UPS systems with operating voltages up to 500V.
- Current ratings from 1.6A to 12.5A, offering reliable protection for high-voltage AC circuits.
- A compact ceramic body (6.3mm x 32mm) that supports more efficient power conversion equipment and is compatible with most commercial low-power supplies.
- An extended operating temperature range of -55°C to 125°C, ensuring performance in harsh environments and extreme temperatures.
Whether for residential, commercial, or industrial use, the 514 Series represents a significant advancement in circuit protection technology, combining reliability, efficiency, and versatility.
40W-360W PERC Mono Solar Cell
PERC monocrystalline panels represent a notable leap forward in photovoltaic technology. These PERC (Passivated Emitter and Rear Cell) panels are engineered to capture sunlight more effectively compared to previous models through the integration of cutting-edge manufacturing processes that boost the electrical efficiency of solar panels. When assembled into mono module configurations, these PERC cells offer several benefits including increased power output, performance that is dependent on cell temperature, a reduced likelihood of hot spot occurrences, and improved resilience against mechanical stress.
Features
1. Cost-Effective: While PERC technology initially has a slightly higher cost compared to traditional solar cells, the increased efficiency often results in lower overall costs per watt of electricity generated over the lifetime of the system. This can lead to quicker payback periods and higher returns on investment.
2. Wide Application: PERC panels are versatile and can be used in various applications, from residential rooftops to large-scale commercial and utility-scale solar farms. Their efficiency and durability make them a popular choice for both new installations and retrofits.
3. Ease of Installation: The structure of PERC panels allows for easier installation compared to some other advanced technologies, such as bifacial cells, which require careful alignment to ensure optimal light capture from both sides.
4. Low Maintenance: PERC panels are less prone to degradation issues like PID (Photo-induced Degradation) and LID (Light Induced Degradation), which can significantly affect the performance of solar panels over time. This means they require less maintenance and can operate reliably for longer periods without significant performance loss.
In essence, PERC solar panels stand out due to their high efficiency, durability, and adaptability, positioning them as a favored option in numerous global solar energy initiatives.
