DESCRIPTION

The RPS6U rack power supplies are designed for use in the machinery protection systems and condition and performance monitoring systems.

A RPS6U rack power supply is installed in the front of a 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.

Either one or two RPS6U rack power supplies can be installed in a 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 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 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.
