How to convert power in dBm to dBW. The power in dBW (P (dBW)) is equal to 10 raised by the power in dBm (P (dBm)) divided by 10: P (dBW) = P (dBm) - 30.
Step-Voltage Regulators applied in the utilityâs distribution systems are generally medium-voltage mechanical automatic voltage regulators (AVR). It should be noted that there are two distinct types of AC automatic voltage regulators: Medium-voltage (mechanical) and the Low-voltage regulators (mechanical or electronic).
The EGR system on recently built vehicles uses a step motor to control the flow rate of EGR from exhaust manifold. This motor has four winding phases. It operates according to the output pulse signal of the ECÎ¼. Two windings are turned ON and OFF in sequence. Each time an ON pulse is issued, the valve opens or closes, changing the flow rate. When no change in the flow rate is needed, the ECÎ¼ does not issue the pulse signal.
