Industrial Power Surge Protection Device TT Connection 48V DC

Product Specification

 Easy Installation Power Surge Protection Device For Industrial Automation
The DC surge protector can be called a surge protector, also known as a lightning protector. It is a very commonly used electronic component. Its applicable current and voltage environment is DC 5V~1500VDC. In this kind of power supply system or communication system, DC wave Surge protectors can protect against transient overvoltage surges caused by direct or indirect lightning. They are widely used in surge protection projects such as households, commercial buildings, industrial fields or the tertiary industry. DC surge protectors protect The modes include relative phase, relative center line, relative ground, center line to ground, and combination.
Surge is also called a surge, as its name implies, it is an instantaneous overvoltage that exceeds the normal operating voltage. Essentially, a surge is a violent pulse that occurs in just a few millionths of a second. The possible causes of the surge are: heavy equipment, short circuits, power switching, or large engines. The products containing surge blocking devices can effectively absorb sudden huge energy to protect the connected equipment from damage.
OBV10-I-15
Surge protectors OBV10-I-15 meet the type 1 requirement class according to IEC 61643-11. These devices protect low-voltage consumer systems from overvoltages of all types and are available in single-pole to four-pole versions.The voltage-limiting,high-performance spark gaps provide several benefits.A short response time, a low protection level and high current leakage capability with long service life.

Transient voltage surgesin lv power lines
Transient overvoltages are voltage surges that can reach tens ofkilovolts with a duration of the order of microseconds.Despite theirshort duration, the high energy content can cause serious problemsto equipment connected to the line, from premature aging to destruction, causing disruptions to service and financial loss.Thistype of surge can have various different causes, including atmospheric lightning directly striking the external protection(lightning rods) on a building or transmission line or the associatedinduction of electromagnetic fields on metallic conductors.
Outdoor and longer lines are the most exposed to these fields,which often receive high levels of induction.
It is also common for non-weather phenomena, such as transformer centre switching or the disconnection of motors orother inductive loads to cause voltage spikes in adjacent lines.
 

 
Importance of theground connection
Overvoltage protectors (SPD) divert excess energy toground, so limiting the peak voltage to an acceptablevalue for connected electrical equipment.
A ground connection in adequate condition is, therefore,a key aspect for effective protection against overvoltages.Monitoring ground connection condition guaranteesproper operation of surge protection devices.
