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. For further information, contact your local Meggitt representative.

Notes 

 1. In 2016, the RPS6U rack power supply was improved to provide a higher output power of 330 W with higher-performance and higher-efficiency, which required a redesign of the underlying power supply circuitry. Accordingly, the different versions of the RPS6U rack power supply in use are: 

 • Later versions of the RPS6U (PNR 200-582-x00-02h or later) that define the power as a total maximum output power of 330 W,   with nominal output (supply) voltages of +5 VDC up to 50 A, +12 VDC up to 8 A and −12 VDC up to 4 A.   Note: The total maximum output power of 330 W is a combination load for all outputs as the +5 VDC and ±12 VDC outputs are   usually not simultaneously loaded to the maximum in practice. For example, if the +5 VDC output is at its maximum rated load   (5.35 V × 50 A = 267.5 W), then the combined loads on the +12 VDC and −12 VDC outputs must not exceed 62.5 W.
