Rack power supply unit (RPS6U)

for a VM600 system rack (ABE04x)

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.

Notes

All AC input rear panels are supplied with a mains power supply lead (no lead is supplied for the DC input versions). See Mains power 

supply leads (power cords) on page 14.

AC input rear panels with mains sockets have an IEC type C14 connector (IEC 60320) that mates with the plug (type C13) used by the 

supplied mains power supply leads.

Rear panels with one input – (a), (b), (c), (d), (e), (f) and (g) – are 2 slots wide / 8 HP (TE).

Most rear panels with two inputs – (h), (i), (j), (k) and (l) – are 4 slots wide / 16 HP (TE).

However, the rear panel with AC and DC inputs – (m) is 2 slots wide / 8 HP (TE).

(The width of 19″ rack is measured in horizontal pitch (HP) units of 5.08 mm (0.2″), also known as standard width (TE) units. For the 

ABE04x rack, a one slot wide (one card position) blank panel corresponds to 4 HP (TE), a two slot wide blank panel corresponds to 8 HP (TE) 

and a four slot wide blank panel corresponds to 16 HP (TE).)

Rear panels with two input connectors that provide a common input to the RPS6U power supplies – (d), (h) and (j) – installed in the rack can 

be used with a redundant external power-supply system.

For additional information on the Rear panel for RPS6U power supply order option codes (Fxxx), refer to the ABE040 and ABE042 VM600 

system rack and ABE056 VM600 slimline rack data sheets.

For the Ordering number:

“NHh” represents the hardware version.

“N” is either “0” for a rear panel according to (and marked) CE low voltage directive or “2” for a rear panel according to (and marked) CCSAUS.

“H” increments are for major modifications that can affect product interchangeability.

“h” increments are for minor modifications that have no effect on interchangeability
