VL-PS Series Reference Manual Introduction – 2

Introduction

The VL-PS Series power supplies are compact, high efficiency supplies designed
specifically to attach to, and become an integral part of the VX or V32 Series STD Bus
card cages. All models feature triple output voltages of +5V and ±12V, and provide the
following output capacity:

VL-PS80 80W 10.0 2.5 0.5
VL-PS100 100W 12.0 3.0 0.5

* 4.0A Peak

All supplies accept wide range AC input with no jumper or wiring changes needed for
different line conditions. A power switch and LED indicator are on the front panel.

Mechanical Assembly

The power supplies are designed to mount on the right hand side of either the VX or
V32, table or rack mount, card cages.

• Remove right hand end plate.

• Remove ventilated cover on power supply.

• (VL-PS80/100 only) remove power supply circuit board for access to mounting

holes.

• Attach power supply base to card cage using four 1/4” pan head screws.

• (VL-PS80/100 only) replace power supply circuit board.

• Replace ventilated power supply cover.

• Attach right hand end plate to power supply using the four original flat head screws.

DC Output

DC output voltages are available on the color coded wiring harness. The front panel
indicator LED wires are also in the wiring harness and are connected to +5V and Ground
on the motherboard. Color coding is as follows:

Installation

1

Connect only one of the black ground leads to AUX GND on the motherboard. The
other two black ground leads should be connected to GND (+5V logic ground).

AC Input

The power supplies are supplied with a standard 120 VAC USA style cord and grounded
plug. An AC input fuse is located on the power supply circuit board. The ground prong
(safety ground) is connected to the metal chassis of the power supply, but is NOT
connected to logic ground.

Front Panel

The power supplies have an AC power switch on the front panel and an LED located
next to the power switch to indicate +5V power is present on the motherboard.
