EMC suppressors

3.2.1

Suppression modules for inductive products simplify the

fulfilment of the EMC law!

Old laws have not lost their validity now. The Ohm´s law is still valid everywhere,

as well as the Lenz´s rule. This states that when an inductive load is switched off,

current has the desire to continue flowing in the same direction and strength as

before. A voltage source is created from the inductive load, which can be many

times higher than the nominal voltage. This voltage spike is the cause of many

EMC problems.

What does the EMC law achieve?

From the 1

the EMC guidelines, can be brought into the European market.

That means:

Products cannot send out interference nor be influenced by it.

Suppression components do not fall under the EMC guidelines.

Reasons for interferences

1. High inductive voltage spikes at inductive loads:

The high voltage spikes when switching off exceed the normal supply voltage many

times and overload the electronics. The voltage can in some cases be so high, that

the windings are shorted and the inductive product is destroyed.

2. High inductive voltage spikes in the automated system:

The voltage spikes climb at a very high speed. These very high climb rates con-

tain high frequencies. Every cable and wire in the control system acts as a trans-

mitter or receiver for these high frequencies.

These high frequency interferences can therefore move unhindered from cable to

neighboring cable.

3. High inductive voltage spikes in the controller:

The present voltage spike at the moment of switching off adds itself in opposite

polarity to the supply voltage and affects the controller i.e. PLC.

These high voltages in the controller cause energy rich arcs, due to the current

flowing on in the same strength and direction at the moment that the contact is

opened. The arcs cause material deformation and reduce the life expectancy of the

switching elements.

Suppression modules for control systems

Murrelektronik supply suppressors for all standard inductive users.

For contactors

For motors

For valves

Murrelektronik solves your interference problems:

Advantage:

Integrated system solutions for all common protectors.

Contactors or relays for universal suppressors can be snaped onto DIN-rail.

Direct suppression inside the motor terminal box.

Motor connection socket 10 + E with integrated suppression and

manufactured cable.

Integrated system solutions for direct mounting.

The universal suppressors should be mounted very close to the source of

interference (motor).

Easy mounting of suppressor.

Optimum interference through individual adaption.

Easy mounting through prefabricated modules – always the perfect

solution.

Less breakdowns increase availability and reduces downtime.

High life span of contacts and control units reduces maintenance cost.

faults in the control process

defective control system

defective coil on the motor, contactor, valve or transformer

interference emissions causing a reduction in functionality
