What is power module? What is an Electronic Circuit Breaker?

Industrial DIN Rail Power Supply may sound unfamiliar to many friends, but it is also very common in our daily life without being noticed. The guide rail is used to install some electrical components such as circuit breakers, contactors and thermal relays, which play a fixed role, while the guide rail power supply actually plays a protective role by monitoring the voltage, current and temperature of equipment in real time.



Power supplies for busbars are also widely used in industry, such as medical industry, machinery industry and so on. They are mainly used in industrial control technology, which is commonly called industrial control. A traction power supply is a device that supplies direct current to industrial control equipment. It can convert alternating current into specific direct current and output it through a guide rail.It usually consists of DC power supply, control circuit and protection circuit. The traction power supply can provide efficient, stable and reliable power supply for various equipment in the industrial field.



It is mainly used in industrial Distribution System and control boxes, because PLCs, contactors, relays, etc. are needed in the industry to support the installation of guide rails. Therefore, power supply for guide rail has become a standard installation method. The power rail, which is also called showcase power rail, is generally divided into three wires and two wires. It is mainly used for some shelves, display cases and light boxes. It is not only simple, beautiful and small, but also saves space.



Design of heat dissipation holes

Honeycomb hollow design for better heat dissipation. Efficient heat dissipation, durable operation and faster hollow heat dissipation. Protects the internal components of the switching power supply.


Filtering hazards

Good insulation and high electrical strength. Soft starting current effectively reduces AC input current surge. With short circuit, overvoltage, overload and overtemperature protection.


Rail-mounted switching power supply

Easy installation, rail mounted installation method. Installation on a guide rail is convenient, time and labour saving.

Electronic Circuit Breaker



What is an Electronic Circuit Breaker? Electronic circuit breaker generally refers to electronic residual current devices, which are electrical switches designed for automatic operation to protect circuits from damage.


If a leak occurs in the protected circuit or a person is electrocuted, the secondary winding of the zero-sequence current transformer emits a signal and causes the leakage trip device to trip the circuit breaker, interrupting the power supply and providing protection against leakage and electrocution.



Svlec Electric has a complete range of electronic circuit breakers that provide intelligent protection for the power system with easy operation and convenient selection.
