V5SC-SER-UPS: Single Board Battery UPS

Overview

35 Watt Single Board NiMh UPS Solution

The V5SC-SER-UPS is a smart 35 Watt DC to DC power supply with +5VDC output. It includes a flash based microcontroller that supplies advanced power management, smart battery charger and an RS232 serial port. The V5SC is designed for low noise embedded computer systems, PC/104 size to fit in a PC/104 stack, has a wide input range of 6-40V (>6:1) and is ideal for battery or unregulated input applications.

Smarts:

• log runtime hours / log excessive temperature operation or shock and vibration/ log input voltage conditions and transient occurrences/ log output voltage and loads
• setup operating parameters such as maximum and minimum operating temperature
• ESN number to uniquely identify each unit
• utilizes a multi-stage charging for both the built-in batteries and the external batteries
• onboard power management function allows timed on/off control of the V5SC, notification of changes to main power and changes in the battery status

Capable:

• a constant off-time current-mode architecture regulator provides excellent line and load transient response for the +5VDC output.
• heavy duty transient suppression up to 6,000 volts
• ripple reduced to below 20mV
• built-in 750mA-Hr 8.4V NiMh battery that is re-charged by the V5SC battery charger; able to provide XX minutes of backup based on X amp draw
• state-of-the-art MOSFET based design provides outstanding line and load regulation with efficiencies up to 95 percent
• supports external battery packs such as the BAT104-NiMh, or a non-PC/104 pack that is wired to the Battery Connector CN1.
• provides up to four stages of battery charging and can charge Lead-Acid, NiCd, and NiMh batteries and is also SMBus level 3 compatible. Charge currents are up to 1.5A, and battery charging voltages from 9.5 to 19.5V.

Applications:

• specifically designed for vehicular applications and has heavy-duty transient suppressors (6000W) that clamp the input voltage to safe levels, while maintaining normal power supply operation.
• low noise design makes the V5SC ideal for use aboard aircraft or military applications or wherever EMI or RFI must be minimized.
• can be programmed to power off the outputs in 60 seconds, and then turn on again 12 hours later
• can be configured to meet almost any power supply and battery charging need for embedded applications, whether that be a simple +5V application, or providing power for back lighted LCD panels, or a full NiMh UPS (un-interruptible power supply configuration).
• all generated voltages are provided to screw terminals. The RS232 serial port is provided on a 2x5 row pin header.

Advantages

• High efficiency
• Extended temperature operation
• Rugged design
• Transient supression
• Power/OS
• Full UPS with smart charging
• PC/104 stackable
