Kepco announces an option for its 200W and 400W BOP models to optimize their
ability to drive capacitive loads. This option (designated by the suffix "C")
makes the BOP more suitable for a wide variety of applications such as solar
cell/panel testing, testing of piezoelectric devices, capacitor testing,
driving and testing of capacitive transducers, and powering industrial or
lab-type applications with capacitive or capacitive-resistive loads.
BOP C option units are designed to operate in a stable
manner in Voltage or Voltage Limit mode for capacitive loads up to 10
millifarads. They are also stable when driving any R-C parallel combination
where load R is > or = to nominal value and C is < or = to 10mF. Load R
(nominal value) = nominal output Voltage/nominal output Current (e.g., BOP
36-6MC, R = 36/6 = 6 Ohms.) Static specifications representing accuracy for
various influence parameters are identical to the standard BOP models. Ripple
and noise specifications are better (approximately 50 percent lower) for the C
option units compared to the standard BOP. Six models (ranging from 20 to 100V
source/sink capability) are available at present. Three additional models are
expected to be available in the coming months.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
