Rack power supply unit (RPS6U)

DESCRIPTION

The RPS6U rack power supply units are designed for 

use in the VM600 series of machinery protection 

systems and condition and performance monitoring 

systems, from Meggitt Sensing Systems’ Vibro-Meter 

product line.

The RPS6U is installed in the front of a VM600 

system rack (ABE04x) with a standard height of 6U 

and connects directly to the rack backplane via two 

connectors. The power supply provides +5 VDC and 

±12 VDC power to all cards in the rack via the rack 

backplane.

One or two RPS6U power supplies can be installed in 

a VM600 system rack. A rack can have two RPS6U 

units installed for different reasons: to supply power to 

a rack with many cards installed, non-redundantly, or 

to supply power to a rack with fewer cards installed, 

redundantly. Typically, the cutoff point is when nine 

rack slots or fewer are used

DESCRIPTION (continued)

When a VM600 system rack is operating with two 

RPS6U units for power supply redundancy, if one 

RPS6U fails, the other will provide 100% of the power 

requirement and the rack will continue to operate, 

thereby increasing the availability of the machinery 

monitoring system.

Various versions of the RPS6U exist, allowing a rack 

to be powered from external AC or DC mains supplies 

with a range of supply voltages.

A power supply check relay, available at the rear of a 

VM600 rack, indicates that the power supplies are 

operating normally. Refer to the ABE040 and ABE042 

VM600 system rack and ABE056 VM600 slimline 

rack data sheets for additional information on power 

supply check relays.

In applications where the VM600 rack is powered by 

an AC mains supply, an auxiliary sensor power supply 

(ASPS) can also be included in the rack. The ASPS 

provides +24 VDC outputs which can be used by 

external hardware such as front-end transducers, 

signal conditioners and galvanic separation units.

For specific applications, contact your nearest Meggitt 

Sensing Systems representative.

TOLERANCE TO MICRO-INTERRUPTIONS IN THE SUPPLY INPUT

The table below shows the maximum permissible duration of a power cut which will not cause MPC4 cards to be reset. 

This value depends on the number of MPC4 cards and RPS6U units installed in the VM600 rack.
