CHAPTER 1 - INTRODUCTION

1.1 GENERAL DESCRIPTION

The HPSC104-SER is a high power, high performance DC to DC converter that supplies +5V, -5V,
+12V, -12V and V5Sby (5V standby) outputs. The HPSC104-SER also includes a flash based
microcontroller that supplies advanced power management, smart battery charger, PC/104 I/O
memory mapped interface and an RS232 serial port. The HPSC104-SER is designed for low noise
embedded computer systems, has a wide input range of 6-40V(>6:1) and is ideal for battery or
unregulated input applications. The HPSC104-SER is specifically designed for vehicular applications
and has heavy-duty transient suppressors (9000W) that clamp the input voltage to safe levels, while
maintaining normal power supply operation.

The HPSC104-SER is a state-of-the-art Mosfet based design that provides outstanding line and load
regulation with efficiencies up to 95 percent. Organic Semiconductor Capacitors provide filtering that
reduces ripple noises below 20mV. The low noise design makes the HPSC104-SER ideal for use
aboard aircraft or military applications or wherever EMI or RFI must be minimized.

The HPSC104-SER 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 4A, and battery
charging voltages from 10 to 35V.

The HPSC104-SER has advanced power management functions that allows timed on/off control of
the HPSC104-SER, notification of changes to main power and changes in the battery status. For
example, the HPSC104-SER can be programmed to power off the outputs in 60 seconds, and then
turn on again 12 hours later.

The HPSC104-SER size is 3.55 x 3.775 inches, and is a fully PC/104 compliant power supply. All
generated voltages are provided to a removable“pluggable” header. A removable plug allows the
HPSC104-SER to be easily installed. The RS232 serial port is provided on a standard DB9
connector.

The HPSC104-SER 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 UPS (un-interruptible power supply configuration).

CHAPTER 2: CONFIGURATION AND INSTALLA TION

2.1 Introduction

This chapter describes the configuration and installation of the HPSC104-SER power supply. In
addition, section 2.2 provides a formula to calculate the available +5VDC. Figure 2-1 shows the
HPSC104-SER connectors, jumpers and other options.

Power Considerations.
The +5V switching regulator is rated at 25A maximum output, however the +5V output supplies power
to the +12, -5, and -12VDC regulators. To obtain the usable range of +5V output, “derate” according
to the use of +12, -5, and -12VDC. Use the following formulae to calculate the maximum usable
output.

Where: I[-5] = -5VDC current load
I[-12] = -12VDC current load
I[12] = 12VDC current load

Assuming 90 percent converter efficiency (actual efficiency may vary).
