CPCI Power Supply General

Page 3

1. Overview

Kontron’s power supply unit family

includes both AC and DC input power

devices with up to 12HP front panels

and 3U in height. The devices are pro-

vided with P-series or DIN M-series out-

put connectors.

The power supply units can be provided

for an output power range of 75 W to

200 W for AC/DC power supply units

and 75 W to 200 W for DC/DC power

supply units with output voltages of

+ 3.3 V, + 5.1 V, and either + 12 V or

±12V.

2. Distinctive Features

The CompactPCI power supplies can

be distinguished according to the follow-

ing distinctive features:

• Form factor (height)

• Front panel dimensions

• Mechanics

• Plug-in compatibility

• Input voltages

• Voltage switching

(AC devices)

• Output power

• Output voltages and currents

• Power supply connector

• Cooling

• Redundant supply capability

• Status indication

• Special features:

Ultra wide input range

Hold-up time > 10ms

EN 50155 compliant

Terminology

Power supply units can be grouped

either according to their form factor: 3U

and up to 12HP where the P-series is

8HP (4.064 cm or 1.6 inch) and the M-

series is 12HP (6.96 cm or 2.4 inch) or

input voltage (alternating current, direct

current).

Input Voltages

Power supply units running on AC input

power are provided with a switching fea-

ture to choose among common US

(Japan) and European AC voltage

ranges. For the sake of understanding

these voltage ranges can be indicated

as the two rated voltages:

•V

US

= 110 V

•V

EU

= 230 V

Voltage Switching

Depending on the power supply unit, the

V

EU

/V

US

switching is accomplished

automatically (”autoranging”) or manu-

ally.

Output Voltages

The common output voltages are

referred to as follows:

• V1 = +5.1 V

• V2 = +3.3 V

• V3 = +12 V

• V4 = -12 V
