EAO rail approved PD/PPS power supplies convert high voltage AC or DC train carriage power to the correct phone or laptop charging voltage for the USB-C sockets.
Using the Power Delivery (PD 3.0) protocol, the EAO USB Programmable Power Supply (PPS) negotiates with the phone, tablet or laptop the correct voltage between 5VDC and 20VDC and the optimal power level to efficiently and rapidly charge the device. Each of the twin outputs deliver up to 60W of power.
The AC input power supplies operate using any global mains voltage, whilst there are two DC versions with either 24VDC or 72-110VDC input.
Housed in a rugged IP40 enclosure for chassis mounting and with reliable screw terminal connections, the range is fully compliant with international railway standards including shock and vibration, EMC and fire protection.
