Power Supplies

Power supplies convert one form of energy to another that is required for proper equipment operation. Protecting against short circuit and excessive voltage incidents, the working longevity of expensive machines will not be compromised. In case of power failure, the electronic devices automatically recover functions to guard sensitive materials. Regulated, unregulated, or adjustable power supplies are categorized based on the general performance producing steady currents or voltages at precise levels.
