Remember, for reasons of minimising power consumption, you want the lowest operating voltage that will still let your logic circuits operate reliably and quickly.
42.
In IEC 60384-1 the allowed operating voltage is called the " rated voltage " U R or the " nominal voltage " U N.
43.
:So in recap, adapter voltage is usually chosen to suit the operating voltages of components in order to reduce power losses and device complexity.
44.
Some variants have current ratings up to 40 A or operating voltages as high as 13, 500 V; others are waterproof and meet IP67 standards.
45.
Because plate voltages can be as high as 300DC, multiple B batteries may be connected together in series to additively provide the required operating voltages.
46.
Refreshing the battery also helps return the battery cells in the string ( where multiple batteries are used together ) to a consistent operating voltage.
47.
The nominal operating voltage for LED backlights is 5V at full brightness, with dimming at lower voltages dependent on the details such as LED color.
48.
When using a high operating voltage, the partial winding of each phase must be insulated against the respective adjacent phase with foil or insulation paper.
49.
JEDEC Standard No . 21 C defines three possible operating voltages for 184 pin DDR, as identified by the key notch position relative to its centreline.
50.
The devices have a wide operating voltage range and include an internal oscillator circuit requiring only the addition of an external resistor to generate the modulation frequency.
