Posambas is a portable and modular power supply for portable ATCS that uses a switching system on the battery used. The portable nature of Posambas makes it easier for users to carry this product. Meanwhile, the modular nature of Posambas is useful so that the battery in this product can be adjusted according to user needs. In the process of supplying energy to ATCS, Posambas is equipped with a control sub-system so that the power sent to the ATCS and the microprocessor at Posambas can be supplied properly even though there are abnormal electrical conditions such as back currents and others. For Posambas to have good modular properties, it is necessary to make an implementation on a Printed Circuit Board (PCB) and a case on this product that supports these properties. In the control sub-system, tests will be given to ensure that the voltage when the battery changes is still around (12± 10%)V, the MCU voltage supply is maintained above 5V when it is operated, and the reverse current flowing in the battery when the switching process is below 1µA. That way, the control subsystem on the product is working properly.
