Surge absorbers are components designed to reduce or limit transient voltage spikes and protect sensitive electronic circuits. They can be used in power supplies, control equipment, lighting products, and other electronic applications. Supreme Electro Devices supplies several surge absorber series, including PTA, PTC, PTB and HVM CZR series.
MOVs and GDTs use different technologies and have different electrical characteristics. *MOVs* are commonly used for fast response to transient overvoltage, while *GDTs* can provide high surge-current handling and electrical isolation under normal operating conditions. The correct choice depends on the circuit design and protection requirements.
A Gas Discharge Tube (GDT) is a surge protection component that uses a gas-filled discharge mechanism to provide protection against transient overvoltages. GDTs can be used in applications requiring high transient current handling and are commonly used for protection of power and communication circuits. The website lists high-current GDTs and BrightKing GDT series among its surge-protection products.
An MOV, or Metal Oxide Varistor, is a voltage-dependent protective component commonly used to suppress transient overvoltage. It provides a low-impedance path during a surge and helps protect connected electronic circuits. Supreme Electro Devices offers different MOV series, including 5D, 7D, 14D, 20D W3 and 25D series, with different voltage and surge-current specifications.
Surge protection solutions can include *Metal Oxide Varistors (MOVs), Gas Discharge Tubes (GDTs), surge absorbers, spark gaps, and power-line protection modules*. The appropriate component depends on the application, operating voltage, surge characteristics, and required protection level.
Voltage surges and transient overvoltages can damage sensitive electronic components and reduce equipment reliability. Proper surge protection can help divert or limit transient energy and reduce the risk of component failure.
A Surge Protective Device (SPD) is an electronic protection component designed to help protect electrical and electronic equipment from transient voltage surges and spikes. SPDs are commonly used in power supplies, control systems, automation equipment, communication systems, LED lighting, and other electronic applications.
