Internet of Things (IoT) has been around almost a decade. Some of the key components in IoT is power supplies, that provide power at the required voltage for the electronic system that handles sensor input and data transfer to the internet. A typical IoT sensor will usually require either 5 volts or 3.3 volts and anywhere between 30 mA to 1 A. ERI Power supply is compact and PCB mountable, available at 5 Volts, 1 Ampere rating. This power supply come up with protection i.e. over voltage, over current and short circuit.
