CHAPTER 1: INTRODUCTION

1.1 GENERAL DESCRIPTION

The HE104 multiple output DC to DC 50 watt converter is a high efficiency, high performance unit

that can be supplied with +5V, +12V outputs only or can include features such as, Power

Management, Universal Battery Charger, AC Bus termination, -5V output, -12V output and custom

output voltages from -42V to +42V. The HE104 is designed for low noise embedded PC/104

computer systems, which has a wide input range of 6 to 40V(>6:1) and is ideal for battery or

unregulated input applications. The HE104 is specifically designed for vehicular applications and has

heavy-duty transient suppressors (5000W) that clamp the input voltage to safe levels. Further, it is

able to maintain normal power supply operation.

The HE104 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,

which reduces ripple noises below 20mV. The low noise design makes the HE104 ideal for use

aboard aircraft, military applications or wherever EMI or RFI must be minimized. The +5VDC and

+12VDC outputs are controlled by a constant off-time current mode architecture regulator, which

provides excellent line and load transient response.

The +12VDC boost regulator uses the +5VDC as input power, so it can operate without dropout from

6 to 40V input and supply 2A. The +5VDC output is protected from output shorts by a high-speed

pulse-by-pulse current limit circuit. Furthermore, +12VDC output is protected from shorts by the

current limiting of the +5VDC controller.

A “plug-in” Universal Battery Charger (BC104) is available for the HE104 to charge Lead-Acid, NiCd

and NiMH batteries. Charge currents can be up to1.5A and battery charging voltages range from 6 to

40V.

The Power Management controller (PM104) allows for timed on/off control of the HE104, bus

interrupts on impending power failure, current limit setting and intelligent charge termination for the

BC104.

The HE104 is provided in a PC/104 form factor compliant size, which includes the 8bit and 16bit

PC/104 expansion bus header. All generated voltages are provided to their related power supply pins

on the PC/104 expansion bus and are available for off-board use through a screw terminal block.

PC/104 AC bus termination is an option that is available on the HE104,that provides the cleanest

possible signals on the PC/104 bus.

The HE104 can be configured to meet almost any power supply need for embedded PC/104

applications. This could be a simple +5V application, which provides for back lighted LCD panels or

a full UPS (un-interruptible power supply configuration).

CHAPTER 2: CONFIGURATION AND INSTALLATION

2.1 Introduction

This chapter describes the configuration and installation of the HE104 power supply. In addition,

section 2.2 provides a formula to calculate the available +5VDC. Figure 2-1 shows the HE104

connectors, jumpers and other options.

2.2 Power Considerations

Usable +5V output =10A – (I [-5] + I [-12]

•

2.4 + I [12]

•

2.4)

0.8

The +5V switching regulator is rated at 10A maximum output however, the +5V output, supplies

power to the +12VDC, -5VDC and –12VDC regulators. To obtain the usable range of +5V output,

“derate” according to the use of +12VDC, -5VDC and –12VDC. Use the following formulae to

calculate the maximum usuable output.

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

I[-12] = -12VDC current load

I[12] = 12VDC current load

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

2.3 HE104 Connectors

2.3.1 Main Input Power Connector

Input power is connected to the “pluggable” block, CN1, which is removable from the socket

connector on the circuit board. 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

-Terminal 2: Common (0VDC)

!! CAUTION !!

To allow operation at the lowest possible input voltages (6VDC) and for the best efficiency, there is

no input Reverse Polarity Diode (RPD) provided on the HE104 without a battery charger option. If

input RPD is required, add RPD to the HE104 part number:

-Example HE 104-512-16-RPD

Note: Adding the RPD results in an increased power loss. For heat dissipation estimation please

refer to section 2.11.

2.3.2 Output Power Connector

Output power is available for non-PC/104 use via connector CN2.

-Terminal 1: +5VDC output

-Terminal 2: Common

-Terminal 3: +12VDC

-Terminal 4: -12VDC output (optional)

-Terminal 5: -5VDC output (optional)

2.3.3 Battery Power Connector (Optional)

Batteries are connected to the screw terminal block, CN3. The HE104 accepts DC battery

voltages in the range of 6.5V to 40DVC through the Battery Power Connector. Two external

signals can be connected to the battery terminal block for use by add-on modules plugged into

the mezzanine header connectors. Connect to the HE104 Battery Terminal Block as follows:

-Terminal 1: Common of battery

-Terminal 2: Positive Battery Terminal

-Terminal 3: External signal 1

-Terminal 4: External signal 2

Note: When Optional Plug-IN Boost regulator (VR3) is ordered, batteries or external signals

cannot be connected to CN3. See section 2.3.4

2.3.4 Onboard PC “Boost” Adaption (Optional)

An optional converter Boost pump (model NMH05XXS, XX=output voltage, + 5V, +9V, +12V,

+15V) can be installed in location VR3 to provide custom output voltages. The NMH charge

pumps have an isolated positive and negative output and a maximum 2-watt capacity. A

minimum load of 10 percent is required for proper operation. By connecting the charge pump to

other voltages, the user can create more or less supplies, as well as elevated and negative

voltages (i.e.: The charge pump “0V” is not connected to the HE104 common).

- Terminal 1: Common of battery

- Terminal 2: -V output

- Terminal 3: 0V

- Terminal 4: +V output
