What is the difference between low voltage release and low voltage protction?

After a power failure, a device with low voltage protection will not restart automatically after power is restored to normal. This normally means that the breaker must be reset. A device with low voltage release automatically starts when power is returned to normal.

How can thermocouple measure the temperature?
Thermocouples are two junctions of two dissimilar metal conductors. One junction is the sensing junction and the other is the reference junction. The voltage between the two junctions depends on the temperature difference between the junctions (Seebeck effect). The voltage can be measured and the temperature difference determined based on known readings of the voltage produced by the metals. If the temperature of the reference junction is known, then the temperature of the sensing junction can be calculated.
What is the difference between ULN2803 and ULN2804?
ULN2802 ULN2803 ULN2804A 8 NPN Darlington transistors, connected in arrays ideal for logic interface level digital circuits (eg TTL, CMOS or PMOS/NMOS) and higher current/voltage such as lamps, solenoids, relays, print Hammers or other similar loads, a wide range of uses: computer, industrial and consumer applications. All device functions are transiently suppressed by collector output and clamping diodes. The ULN2803 is designed for standard TTL compliance, while the ULN2804 is manufactured to fit 6 to 15V on high-level CMOS or PMOS. The circuit is a reverse output type, that is when a low-level voltage is an input, the output terminal can be turned on to work. For more, The ULN2803 and ULN2804 have the same pinout and current parameters. But there is a little difference. The drive voltage of ULN2803 is 5V for TTL and CMOS circuits. The driving voltage of ULN2804 is 6V-15V for CMOS and PMOS circuits. Reference: The Overview of ULN2804A [FAQ] [ utmel]
What is supermesh and supernode?
When a voltage source comes in between two nodes, we call it a supernode. When a current source comes in between two meshes, we call it a supermesh.
How do you calculate line regulations?
no load voltage - full load voltage by full load voltage
If your voltage vs distance graph is not linear what could have caused this result?
voltage= f(ln(r)) graph is linear and voltage vs distance is non linear because voltage changes with 1/r so the graph is with curve. we use ln because ln direct the graph.
What is the Difference between supply voltage and input voltage?
no difference...
What is the difference between a voltage converter and a voltage regulator?
the difference between a voltage converter to a voltage regulator,is that a voltage converter,converts or changing the desired voltage to be used while the voltage regulator,regulates the input of the voltage amount not to excess to its inputs.
Why voltage is measured between 2 points?
because voltage is the 'electrical potential difference'. since a "difference" can only be evaluated between two points so is voltage :)
What is difference between retarding voltage and a voltage?
A retarding voltage is what causes the electronic to shut down.
What is the difference between cut in and break down voltage?
what is the difference between cut- in and cut -out
What is the importance of voltage?
importance of voltage is the potential difference between two points.
The difference in voltage between the two sides of a device is called?
Voltage drop.
What is produced first current or voltage?
current flows as a result of potential difference i.e. in a circuit if there is no voltage difference between two points, no current can flow between those two points. So voltage has to be produced first.
What is the difference between voltage forward voltage and voltage drop?
Voltage is the potential difference between the source & any point in the circuit. The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). Voltage drop means, amount of voltage by which voltage across load resistor is less then the source voltage.
What is positive and negative voltage value?
generally we calculate voltage difference not absolute voltage but we say it voltage so if V(AB) is positive then V(BA) will be negative.V(AB) means voltage difference between A and B.
What is the difference between voltage and Celsius?
Voltage measures electrical tension, Celsius measures temperature.
What is The Voltage Of each wire in Straight 220V Circuit?
Voltage is not an absolute figure. Voltage Difference is the exact term. So, the voltage difference between the two wires in the 220 V circuit will be 220V.
