Industries require three phases of energy to run their machinery. Some of them require continuous uninterrupted power to maintain their data. The automatic phase selection unit is introduced for those devices whose power is single-phase. The single-phase supply is automatically selected from the three-phase supply.
The purpose of the APS is to ensure that commercial power is continuously delivered to the site at all times to ensure that the transceiver base station (BTS) runs on commercial power until all available phases are out of electrical tolerance or completely off. It is a unit based on microcontrollers and is used with three-phase power supply. When the supply of one or two phases of a three-phase power line is switched off, the APS system automatically distributes the power of the active phase to the failed phases. This ensures a continuous feed through the three phases even if a phase is active.
The user can operate this system in automatic and manual mode. In automatic mode the phase is automatically selected by the controller so that there is an uninterrupted continuous supply to the unit.
In manual mode, the user will select the desired phase.
A microcontroller-based system will continuously monitor the incoming phase and therefore display details on an alphanumeric LCD display will also show the output phase.
Technical specification
1. Supervise the three phases and pass one of them.
2. Displays all available phases on the LCD
3. An LCD screen and keypad with three keys are provided for user input.
4. If a phase is disconnected. The new phase (S / T) will be selected immediately and will remain connected.
