PPM-PS394-533 PC/104-Plus DC/DC Power Supply with Dual Inputs, MPPT Smart Battery Charger, and UPS Controller Features • Wide input range: 9V to 32VDC • Dual fused inputs accept solar panel, wind turbine, or other DC sources • Automatically selects best input source and provides rapid switchover • UPS operation with battery pack • Battery charger supports Lead Acid, Li-Ion/Polymer, LiFePO, and SLA chemistries • MPPT charging supported for solar panels • NTC thermistor input to monitor temperature • Jumper configurable EOC and Float voltage • Voltage output: +5V @ 5A and +3.3V @ 5A • No minimum load required for regulation • Outputs have short circuit/overload protection • Six LEDs provide visual indication of the DC power inputs, battery, and charger status • No fan or heat sink required • -40° to +85°C operation supported Product Description WinSystems’ PPM-PS394-533 is a dual output, wide input range, DC/DC converter with a built in battery charger and uninterruptable power supply (UPS) controller. It provides power to a single board computer (SBC) from a wind turbine, solar panel, battery or other DC source. This product can be used for off grid applications in harsh temperature ranges from -40° to +85°C. • Small size 3.6 x 3.8 inches (90 x 96mm) • RoHS compliant WinSystems’ PPM-PS394 is designed to sit between one or two 9 – 32 volt power sources and convert them to separate +5V and +3.3V outputs to power a PC/104-Plus system. The supply also simultaneously charges a 6 or 12 volt battery with a maximum power point tracking (MPPT) battery charger for Lead Acid, Li-Ion/Polymer, LiFePO, and SLA chemistries. Power is available on the PC/104, PC/104Plus, and auxiliary connectors. The supply continuously monitors the two external DC inputs and takes power from the source with the highest voltage. If both inputs drop below 9VDC, the control module automatically switches to an external battery input and continues to provide uninterrupted power to the 5V and 3.3V outputs. When one or both external DC inputs are restored, the supply switches input back to the source with the highest input voltage and begins charging the battery until either the charge current drops below 200mA or a user configured end of charge (EOC) time limit is exceeded. A 10KΩ NTC thermistor can be mounted at the battery which will shut down the charger if the battery temperature is too high or too low.

PPM-PS394-533: PC/104-Plus DC/DC Power Supply The UPS feature provides a fast switchover which is free of oscillations between the two external sources and battery. Switching is accomplished in less than 500nS and hysteresis prevents oscillation. The battery charger employs a CC/CV charging characteristic and is capable of charging a variety of different battery chemistries. The charger float voltage and charge termination schemes are user programmable allowing batteries as low as 6V and as high as 12V to be used. The battery charger is a maximum 2A charger that features MPPT for use with solar...
