Gas Discharge Tube Arresters (GDT); encompass a wide range of passive electronic components designed to protect electrical and electronic circuits from high voltage surges and transient voltages. This technology is used extensively in a variety of industrial applications, ranging from commercial to military, due to its capacity to provide consistently reliable protection in the face of extreme electrical conditions.

2027-20-BLF (or BLF-2027-20) is one of the most popular Gas Discharge Tube Arresters on the market, and has become increasingly popular for its versatility and high performance. The same proven protection technology can be found in circuits ranging from computer systems to space satellites. It is especially suited to applications with long electrical leads, as it can provide continuous protection over a wide range of currents.

The 2027-20 BLF’s working principle is relatively simple; the unit consists of a gas-filled enclosure containing two electrodes separated by an insulation material. When a high-voltage surge travels along the electrical circuit, it will encounter the GDT, and the surge will cause the gas inside to ionize, creating a spark-gap. This spark-gap will absorb the energy contained in the surge, protecting the circuit components from the potentially destructive effects.

The voltage passing through the spark-gap will quickly be extinguished, and the GDT will return to its initial non-conducting state. In order to ensure reliable protection even in the face of multiple surges, the 2027-20 BLF has a Fast Recovery Time (FRT) of less than 5μs, allowing the unit to reset quickly to its initial non-conducting state.

The 2027-20 BLF has several advantages over other GDTs; it has an unusually long life-span, able to withstand up to 50,000 A impulse current. Its wide operating temperature range of -40 to +125°C allows it to be used in a variety of industrial settings, and its highly durable construction ensures excellent operational stability during extended exposures to extreme voltage surges and current fluctuations.

Aside from providing reliable over-voltage protection, the 2027-20 BLF has been proven to offer circuit designers a number of additional benefits including improved safety against counterfeiting, environmental compatibility, and straightforward installation without the need for additional wiring. It also provides excellent long-term protection in critical applications such as emergency power supplies, medical electronics, and critical infrastructure.

The 2027-20 BLF is designed to meet the requirements of the IEC 61000-4-5 standard, and is manufactured in accordance with the latest IEC specification. It is also available with a range of extra features such as an inrush current protection system and an overvoltage protection system, allowing for additional protection against nuisance tripping due to high transient voltage events.Overall, the 2027-20 BLF is an incredibly reliable and versatile GDT, suitable for a wide range of industrial applications. The unit’s combination of features makes it an ideal choice for those seeking reliable, long-term protection from transient voltages and surges.
