Trusted Power System
Product Overview
The Trusted® Power System is a high density flexible power supply designed to convert main line
voltages of either 110 Vac or 240 Vac. Outputs are either 24 Vdc for Trusted product or 28 Vdc
adjustable field power.
The Trusted Power System consists of a 1U Power Shelf with mechanical support, containing up to
three 750 W Power Packs. The Power Packs load share in configurations using one or more Power
Shelves. Each Power Pack has an individual supply connection via a mechanically retained IEC 60320
type connector. Each Power Shelf can supply 2250 W of power or 1500 W with n+1 redundancy
from a single source. Multiple units can be connected for further capacity or redundancy
requirements.
Diagnostic information of Power Pack status is provided via the Power Port, which connects to the
rear of the Power Shelf. This device monitors input and output conditions and reports out of range
faults and over-temperature/fan failure using relay contacts. The Power Port also allows connection
of the optional rack mounted Power Controller for live configuration, of output voltage and current,
monitoring up to 12 Power Packs in 4 Power Shelves.
Features:
• Redundant and N+1 configurations.
• Hot replaceable Power Packs.
• Current sharing.
• Current limiting.
• Power factor correction.
• Diagnostic contacts.
• Configurable output voltage.
• Input/output fail diagnostics per power pack.
