10/350 µs Waveform (Type 1 SPDs): features a rise time of 10 microseconds and a more protracted duration of 350 microseconds.
8/20 µs Waveform (Type 2 SPDs): This waveform exhibits a rapid rise time of 8 microseconds and a relatively extended duration of 20 microseconds.
Equipment connected to Alternating Current (AC) networks may be exposed to various undesirable electrical phenomena, which can disrupt their operation, cause failures, shorten their lifespan, or even destroy them.
AC Type 1 surge protection device (SPD) is characterized by a 10/350 µs lightning current waveform.
DIN-Rail AC Type 1 surge protection devcie SPD installed at the load center’s main circuit breaker, e.g. main distribution board.
An AC Type 1 surge protection device (SPD) with remote signaling terminals is designed for remote monitoring and management.
These terminals facilitate real-time monitoring of the SPD’s operational status, provide alerts in case of faults, and enhance system safety by enabling quick response to issues.
AC Type 1 SPD manufacturing includes market research, design, component procurement, assembly, testing, certification, packaging, distribution, and after-sales support.
We use high-quality LKD MOVs in our AC Type 1 surge protection devices.
MOVs are sealed in epoxy for environmental protection, moisture resistance, safe handling, and insulation.
With superior quality of MOVs, the surge protectors manufactured by LSP are safe to use for up to 5 years.
During the manufacturing process of a Type 1 Surge Protective Device, product testing is a crucial step.
This includes market research, design, component procurement, assembly, encapsulation, electrical and thermal testing, and safety and compliance testing.
Finally, the product undergoes certification, packaging, distribution, and after-sales support.
The AC Type 1 Surge Protective Device features robust packaging, providing secure and reliable protection during transportation. This ensures the device can operate safely even in harsh electrical environments.
The manufacturing process of an AC Type 1 Surge Protective Device (SPD) involves determining requirements, designing, selecting components, assembly,
testing, installation, and certification to ensure high reliability and effectiveness.
Type 1 Surge Protection Devices (SPDs) protect residential, industrial, hospital, and commercial buildings from electrical surges, especially from lightning, ensuring safety, reliability, and longevity of electrical systems.
Industrial environments often house critical machinery and sensitive electronic controls that are highly susceptible to damage from electrical surges.
Type 1 surge protection devices are essential in such settings to protect against the high-energy transients that can result from lightning strikes or heavy-duty electrical operations.
Installing these devices at the main distribution boards helps to maintain operational continuity and prevent costly downtimes.
In commercial buildings, the reliability of electrical systems is paramount.
From office complexes to shopping malls, the protection of lighting systems, HVAC units, elevators, and other essential services is critical.
Type 1 surge protective devices ensure that the electrical infrastructure remains intact during electrical disturbances, thereby safeguarding the business operations and enhancing the safety of occupants.
Homes have lower electrical demands than industrial sites but are still vulnerable to surges, especially from lightning.
Installing Type 1 surge protector devices at service entrances protects household appliances and electronics, ensuring safety, safeguarding investments, and preventing costly damages.
This simple measure provides peace of mind for homeowners.
In hospitals, Type 1 Surge Protection Devices (SPDs) are used to protect medical equipment, power systems, and data security from high-energy surges and transient overvoltages.
By ensuring the stable operation of equipment and compliance with safety standards, Type 1 SPDs help maintain continuous patient care and the reliable functioning of critical hospital services.
