rack of modules (cards)

• Two RPS6U rack power supplies enable rack

power supply redundancy

DESCRIPTION

The VM600Mk2/ VM600 RPS6U rack power supplies

are designed for use in the VM600Mk2/ VM600

series of machinery protection systems and

condition and performance monitoring systems,

from Meggitt’s vibro-meter ® product line.

A VM600Mk2/ VM600 RPS6U rack power supply is

installed in the front of a VM600Mk2/ VM600 ABE04x

system rack (19 ″ system racks with a standard

height of 6U) and connects via two high-current

connectors to the VME bus of the rack’s

backplane. The RPS6U power supply provides

+5 VDC and ±12 VDC to the rack itself and all

installed modules (cards) in the rack via the rack’s

backplane

DESCRIPTION (continued)

Either one or two VM600Mk2/ VM600 RPS6U rack

power supplies can be installed in a VM600Mk2/

VM600 ABE04x system rack. A rack with one

RPS6U power supply (330 W version) supports the

power requirements for a full rack of modules

(cards) in applications with operating

temperatures up to 50 °C (122 °F).

Alternatively, a rack can have two RPS6U power

supplies installed in order to either support rack

power supply redundancy or in order to supply

power to the modules (cards) non-redundantly

over a wider range of environmental conditions.

A VM600Mk2/ VM600 ABE04x system rack with two

RPS6U power supplies installed can operate

redundantly (that is, with rack power supply

redundancy) for a full rack of modules (cards).

This means that if one RPS6U fails, the other will

provide 100 % of the rack’s power requirement so

that the rack will continue to operate, thereby

increasing the availability of the machinery

monitoring system.

Note: This is known as a redundant RPS6U rack

power supply configuration.

A VM600Mk2/ VM600 ABE04x system rack with two

RPS6U power supplies installed can also operate

non-redundantly (that is, without rack power

supply redundancy). Typically, this is only

necessary for a full rack of modules (cards) in

applications with operating temperatures above

50 °C (122 °F), where RPS6U output power derating

is required.

Note: Even though two RPS6U rack power supplies

are installed in the rack, this is not a redundant

RPS6U rack power supply configuration.

The number and type of RPS6U power supplies

installed in a VM600Mk2/ VM600 ABE04x system

rack, together with the number of modules

(cards) installed and the environmental

conditions, helps determine the mode of

operation of the RPS6U power supplies as either

redundant or non-redundant. See also Ordering

information on page 16.

Different versions of the RPS6U rack power supply

enable a VM600Mk2/ VM600 ABE04x system rack

to be powered using external AC and/or DC

mains supplies. All RPS6U power supplies support a

wide input voltage range.

A power supply check relay, available on the

associated rear panel at the rear of a VM600Mk2/

VM600 ABE04x system rack, is used to indicate

that the RPS6U power supplies are operating

normally. Refer to the VM600Mk2/ VM600 ABE04x

system rack data sheet for further information.

In applications where the VM600Mk2/ VM600

ABE04x system rack is powered by an AC mains

supply, a VM600Mk2/ VM600 ASPS auxiliary sensor

power supply can also be included in the rack.

The ASPS provides +24 VDC outputs which can be

used by external sensor/measurement chain

hardware such as front-end sensors, signal

conditioners and galvanic separation units.
