Gas Discharge Tube Arresters (GDT) are protective devices used in electrical circuits and electronic systems to protect the components from surges, spikes, and voltage spikes. The 2089-250-BLF GDT is a versatile, easy-to-install, and reliable surge protection device. It’s designed to provide reliable protection from line-to-ground and line-to-line transients on AC, DC, or low-voltage power lines.

The 2089-250-BLF GDT is used in the fields of communication networks, broadcast and CATV transmission systems, telecommunication sets, telemeters, and industrial control systems. It’s also suitable for installations that require protection from voltage transients on low-voltage power lines.

The 2089-250-BLF GDT has a wide relay disconnecting capability of up to 250 mA. When connected to a two-pole or four-pole relay, the 2089-250-BLF GDT can switch off the power supply in the event of a surge or a voltage transient. This triggers an off-delay of up to 1.5 seconds to allow for additional current to flow through the power supply.

The working principle of the 2089-250-BLF GDT is quite simple. It has a solid-state sensing element which is highly sensitive to voltage transients. When a voltage transient is detected, the discharge tube breaks down, allowing the connected DC power pack to disconnect. This triggers an off-delay, which keeps the power supply off until the transient subsides and the normal voltage returns. To prevent further damage, the 2089-250-BLF GDT also features a narrow voltage range that helps to limit the range of overvoltages that can affect the system, thus providing additional protection.

The 2089-250-BLF GDT is also equipped with a fault indicator that changes depending on the type of surge it has detected. This helps the user diagnose the cause easily. The 2089-250-BLF GDT also features a short circuit protection which prevents secondary surges, thereby increasing the stability of the electrical system.

The 2089-250-BLF GDT is a reliable surge protection device with a wide relay disconnecting capability and an effective fault indicator. It is suitable for applications such as communication networks, broadcast and CATV transmission systems, telecommunication sets, telemeters, and industrial control systems. With its reliable protection from voltage transients, short circuit protection, and effective fault indicator, the 2089-250-BLF GDT is an excellent choice for reliable surge protection.
