Voltage Drop: Defined

Voltage drop explains how the energVoltage-Drop-Caused-1y of a voltage source is decreased as electrical current moves through the passive elements (elements that do not supply voltage) of an electrical circuit.  The issue becomes important when the length of a run of wire becomes elongated.  A common analogy used to explain voltage, current, and voltage drop is a garden hose.   Voltage is analogous to the water pressure supplied to the hose. Current is analogous to the water flowing through the hose. And the inherent resistance of the hose is determined by the type and size of the hose, just as the type and size of an electrical wire determines its resistance.

Overmolded or Assembled Power Connectors?

NEMA 5-15P_BLACKWhen it comes to selecting a power cord for your electronic device, you can either choose between a field- assembled (or mechanical) cable or an overmolded (molded) cable.  An overmolded cable is built using an injection molding process, which combines two or more materials with a molded plastic component over them to create a single part.  Molding consolidates materials and parts, it usually eliminates the need for additional assembly.  Overmolded cords increase reliability and deliver a completely assembled product.

Quick-Release Power Cords

QUICK-RELEASEHave you ever found yourself recklessly yanking out a power cord from an outlet, and afterwards realized that you a) broke something, b) nearly broke something, or c) caused unnecessary physical strain on yourself or your power cord?  If you’ve answered yes to any of these questions then there’s a solution to your problem.

The Quick-Release power cord series offers an alternative way to unplug your valuable electronics.  A simple pivoting release tab on each connecting end of the power cord makes it easy to disconnect your device without the physical strain or electrical hazard of yanking a plug from a wall outlet or power strip.  It also eliminates the “yanking” problem, thus the deterioration/split of the conductors inside the cord.

Summertime Heat – How to Protect Your Data Centers and Electronics

summerheatpalmtree-587117Ahh, Summer.  It’s already  one of the hottest years on record for much of California, and in light of  soaring temperatures, it’s an important time to closely monitor your valuable electronics and data centers.  You’ll want to make sure air-conditioning and water-cooling systems are working properly, but there are more steps you can take to ensure your electronics survive the heat.

Fact:  Electronic devices tend to run 10-20 degrees higher than room temperature. If temperatures become too hot, outside cooling and ventilation is needed to prevent overheating.  While air-conditioning may fit the bill, in some cases you may want invest in an environmental monitoring system to ensure your electronics keep safe.

Ferrite Beads: What are they?

IEC-60320-C13 GREY WITH FERRITE_GREYYou see them all the time on your power cords. They may look like a little mini donuts or tubes close to one end of the power cord but what are they and why do we need them? Those are called ferrite beads and they are very useful in reducing electromagnet interference (EFI) and radio frequency (RFI). This can be important when you don’t want your machines to have any disruptions or interference of other kinds of signals. The beads can also be referred to by different names such as blocks, cores, rings, EMI filters and chokes.
