CHAPTER 1 INTRODUCTION

1.1 GENERAL DESCRIPTION

The HE104-75W is a high eff ic ienc y, high perf ormance DC-to-DC converter that s uppl ies +5 V, +12V & -12V outputs to the
PC/104 bus. The HE104-75W is designed for low noise embedded computer systems, has a wide input range of 6­40V(>6:1) and is ideal for batter y or unregu lated inp ut app licat ions. T he HE104-7 5W is specif ically design ed f or vehicular
applications and has he avy-dut y transient s uppress ors (9000W on m ain input) that c lamp the input voltage to safe levels ,
while maintaining normal power supply operation.

The HE104-75W is a state-of-the-art Mosfet based design that provides outstanding line and load regulation with
efficiencies up to 90 perc ent. O rganic Sem iconduc tor C apacitor s pro vide fi ltering that re duces ripp le no ises belo w 20m V.
The low noise design m ak es the HE104-75W ideal for use aboar d aircraf t or m ilitary applic ations or wherever EMI or RFI
must be minimized. T he +5VDC and +12VDC outputs are controlled b y a constant frequenc y architecture regulator that
provides excellent line and load transient response.

The HE104-75W has an opto-couple d on/off input ( SD) to contro l the outputs of the HE104-75W. To enable the HE1 04­75W outputs, a 6 to 40V signal m ust be connected t o the SD input. If remote c ontrol is not requir ed, the S D input can be
connected to the main pow er input. The common for the remote 6 to 40V signal mus t be connected to the HE104-75W
common. If the SD input is connec ted direc tl y to the m ain input power c onnec tor, the c omm on for the SD input is alre ad y
done.

CHAPTER 2 CONFIGURATION AND INST A LLATION

2.1 Introduction

This chapter describes the configuration and installation of the HE104-75W power supply. In
addition, section 2.2 provides a formula to calculate the available +5VDC. Figure 2-1 shows the
HE104-75W connectors .

2.2 Power Considerations.

The +5V switching regulator is rated at 15A maximum output, however the +5V output supplies power
to the +12, 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[-12] = -12VDC current load
I[12] = 12VDC current load
Assuming 90 percent converter efficiency (actual efficiency may vary).

2.3 Main (CN2) Input Power Connector

Input power is connected to the HE104-75W by removable connector blocks CN2. The power supply
accepts DC input voltages in the range of 6VDC to 40VDC.

Unregulated vehicle power is connected as follows:

- Terminal 1:“hot” polarity (6-40VDC)

- Terminal 2: Common (0VDC)

2.4 Output (CN4) Power Connector

Output power is available for use via connector block CN4 and is applied directly to the power and
ground connections on the PC/104 bus (refer to 2.2.3 for a listing of power and ground connections
on the PC/104 bus).

Note: SD is an opto-coupled input signal used to turn on/off the outputs. To enable the HE104-75W
outputs, a 6 to 40V signal must be connected to the SD input. If remote control is not required, the
SD input can be connected to the main power input. The common for the remote 6 to 40V signal
must be connected to the HE104-75W common. If the SD input is connected directly to the main
input power connector, the common for the SD input is already done.

CN4 Connections

- CN4-2: Common

- CN4-3: -12VDC output

- CN4-4: +12VDC output

- CN4-5: Common

- CN4-6: +5VDC output

- CN4-7: Common

- CN4-8: SD (i.e. maintained contact closure)

The table below lists the pins used by the HE104-75W for power and ground on the PC/104 bus.

2.6 LED Enable/Disable

There are no jumpers on the HE104-75W to disable the LED. If the LEDs must be disabled then the
current limiting resistor can be easily removed. The HE104-75W can be factory ordered in this
configuration for OEM quantities. Please contact Tri-M sales for det ai ls .
