FXWA9306 Dual Bi-Directional I C-Bus® and SMBus Voltage- Level Translator
FXWA9306 Dual Bi-Directional I C-Bus® and SMBus Voltage- Level Translator

... As with standard I2C-bus systems, pull-up resistors are required to provide the logic HIGH levels on the translator’s bus. The FXWA9306 has a standard open2 drain configuration of the I C-bus. The size of these pullup resistors depends on the system, but each side of the translator must have a pull- ...

Voltage optimisation

Voltage optimisation is a term given to the systematic controlled reduction in the voltages received by an energy consumer to reduce energy use, power demand and reactive power demand. While some voltage 'optimisation' devices have a fixed voltage adjustment, others electronically regulate the voltage automatically.Voltage optimisation systems are typically installed in series with the mains electrical supply to a building, allowing all its electrical equipment to benefit from an optimised supply.
