| CONTINUAL SHORT CIRCUIT & OVERLOAD PROTECTION

Switch mode power supplies have different power-down characteristics that make sure the unit’s electronics are protected when overloads or short circuits occur. Murrelektronik’s switch mode power supply modules use one or more the following technologies to protect the circuit:

Hiccup Mode/Auto Restart Power Limiter Current Limiter

• Powers down in case of error

• Restarts automatically when error is fixed

• Starts large loads reliably

• Limited function in case of error

The Power Limiter and Current Limiter functions are excellent for starting capacitive loads. Units with these features do not simply switch off, but they reduce the voltage or provide a higher inrush current with the Power Boost function.

Before changing over into this protected mode, many of Murrelektronik’s power supplies provide an over current four times larger than the nominal current for a few milliseconds. This is another great advantage.

The Power Boost function provides up to 50% more power for up to 4 seconds. This allows you to start higher loads and capacities without having to have a second power supply unit. Available with Emparro or Evolution.

CIRCUIT MONITORINGREDUNDANCY & BUFFERING

Do you recognize any of these 24V DC control circuit problems?

• Sensor and valve cables get very hot, melt or catch fire without the breaker reacting

• We have to shut down the machine to reset a breaker, repair sensor cables or replace a fuse

• We have to open the control cabinet to see which breaker or fuse failed, and keep the cabinet open to troubleshoot a circuit

• The power supply shuts down during a short circuit or overload

• We oversize our power supply to prevent it drawing down before our breakers trip

• We oversize our breaker or fuse to avoid them blowing during machine start-up

• We have to keep many different breakers and fuses in stock

| DRAWBACKS OF TRADITIONAL BREAKERS & FUSESIf you experience any of these problems, you are feeling the pain of using traditional circuit break-ers and fuses to protect 24V DC control circuits.

When you look in a typical control cabinet, you spot glass fuses, cartridge fuses or circuit break-ers. These devices have been wired and sized the same way since they first became commercially available in the 1930s. Over the years, control engineers have learned to live with the way these devices operate.

You expect them to react when a cable is cut or damaged. You expect to replace or reset them whenever this happens. You expect them to react faster than your power supply.

But despite their familiarity, traditional breakers and fuses have some distinct drawbacks, such as slow reaction time, limited sensitivity, and no help in troubleshooting. As you know, it can be time-consuming and costly for personnel to open a control cabinet—or even worse, shut down a whole production line—while technicians strive to troubleshoot a circuit.

Sometimes you can’t afford to live with these limitations. Sometimes you replace an installed breaker or fuse with a higher-current version to prevent nuisance tripping. Sometimes you replace a power supply with a larger model with a higher protection point so you won’t lose an entire control circuit if the breaker fails to react. And sometimes you worry if your cables and devices are properly protected.

| TODAY’S SOLID-STATE CIRCUIT PROTECTIONControl engineers have an alternative: a more modern form of circuit protection and x monitoring device based on solid-state electronics (microchips). “Electronic fuses” have proven themselves in the field for more than 10 years, in many applications. For example, similar technology is now routinely used to protect switch-mode power supplies. Engineers in many other fields have come to appreciate the benefits of solid-state electronics over electromechanical devices. These advantages include: • Faster reaction time• More precise operation• Lower power consumption• Less electrical “noise” output• Smaller size and lighter weight• Less sensitive to mechanical shock, vibrations, humidity or magnetic fields• Longer life expectancy

| COMPARE THE PERFORMANCE OF BREAKERS TO SOLID-STATE PROTECTIONPerhaps you are not sure how reliable an electronic circuit-protection device can really be? To compare performance of older and newer devices, look closely at the trip curves shown in Figure 1. Notice how a traditional 24V DC thermal breaker compares to a 2A electronic device. Look at the reaction times in the accompanying table. While waiting for the bi-metal components of a thermal breaker to react to a short, cables and devices can be exposed to massive over-current. While 8A of current takes 9 seconds to trip the 2A breaker, the same current will trip the electronic device in only 10ms—900 times faster.

The same occurs with the 6A devices shown in Figure 2. In this case, 12.5A will take 50 seconds to trip the breaker, but only 10ms to trip the electronic device—5,000 times faster!

How can we explain such dramatic improvement in reaction times? Electronic protection devices use a precise set point as a reference, and react as soon as the current goes beyond that set point. This protects all cables, conductors, and devices from exposure to unnecessary current, hundreds or thousands of times faster than a traditional breaker. Imagine how much damage you could avoid by cutting almost a minute of over-current stress from your sensitive loads.

Having the highest machine availability is an important subject. That’s why power supply systems are often designed redundantly: with two power supply units. Murrelektronik’s active redundancy module, MB Redundancy Balance, decouples two independent power supply units and generates a redundant 24V DC control voltage.

MB Redundancy Balance ensures an automatic 50:50 balancing of power between the two units. For example: if the required load current is 10A, this cabinet component ensures that both units supply 5A. If one of the two power supply units fails, the other will continue to work because it is decoupled. If this situation should occur you must make sure that your remaining power supply is sized to handle the entire load.

MB Redundancy Balance operates with an innovative technology based on MOSFET. Depending on the output current and the input voltage difference, the internal consumption of the modules is up to 87% less than with conventional diode modules.
