ORLN100.V Application Field and Working Principle

ORLN100.V is an adjustable current limiting fuse, a power electronic protective device with overload or short-circuit protection in low voltage DC circuits. This fuse is mainly used in photovoltaic (PV) systems, DC-DC converters, motor drives, and other non-linear loads. It has two main characteristics, one is high current overload protection, the other is simple short circuit protection. The following sections will introduce the application field, working principle and features of ORLN100.V.

Application Field

ORLN100.V is mainly used for low voltage DC circuit protection. It provides reliable and non-interference protection for the circuit, and efficiently improves the system. The specific application areas are:

• Photovoltaic (PV) systems: PV solar panels and other parts of the circuit with high current demand in PV systems need to be protected by the fuse.
• DC-DC converters: ORLN100.V ensures the safety of dc-dc converter circuits by accurately controlling the maximum current flowing in the DC circuit.
• Motor drives: This fuse can protect motor circuits from short circuits, overloads and other accidents by accurately controlling the maximum current.
• Non-linear loads: In non-linear loads, ORLN100.V offers reliable protection with its precise current limiting feature.

Working Principle

The working principle of ORLN100.V fuse is based on the melting heat that the fuse wire absorbs and its own melting point, when the current of the system exceeds its rated current, the heat absorbed by the fuse wire exceeds its own melting point, and the current carrying fuse wire melts and interrupts the circuit, then the ORLN100.V fuse works.

ORLN100.Vs have two main characteristics, one is the high current load overload protection, the other is the simple short circuit protection. For the high current overload protection, the rated current of the fuse needs to be carefully considered according to the rated current of the load or the circuit being protected, the fuse should always be lower than the rated current of the load in order to avoid damaging the display panel. For simple short circuit protection, an arc will be formed by the short circuit, which will be cooled by the self-heating of the fuse and the thermal effect of the arc, thus avoiding damage to other components of the circuit.

Features

ORLN100.V is designed with multiple features to meet the high safety and reliability requirements.

• Efficient current limiting: ORLN100.V fuse can protect circuit and components from over current accidents.
• High accuracy:ORLN100.V provides a very accurate current limiting design with 0.02 ohm impedance and a current limit of 2-180 A.
• Low voltage drop : This fuse further reduces the voltage drop of the system by providing a low resistance value.
• High reliability: The fuse is designed to protect the circuit from overload and short-circuit, ensuring the reliability and safety of the system.
• High power capacity: ORLN100.V features high power capacity of up to 600A and maximum voltage of 24 to 32V.
• Easy installation and replacement: the fuse body is adjustable to fit different mounting configurations and enables easy installation and replacement.

In summary, ORLN100.V is an adjustable current-limiting fuse, widely used in PV, DC-DC converter, motor drive and other non-linear load system. It has many features such as accurate current limiting, low voltage drop, high power capacity and easy installation and replacement, which make it an ideal choice for these circuits.
