Trusted High Integrity Power Supply System

(110-240 Vac and 24 Vdc)

Product Overview 

The Trusted® power supply assembly converts redundant main line voltages of either 110

Vac / 240 Vac or 24 Vdc, to +15 Vdc or +24 Vdc output power for system and field power

requirements.

Features:

• Redundant power inputs.

• 250 W.

• Hot replaceable.

• Current sharing.

• Power factor correction.

• Front panel indicators for input, output voltage status and output current level on each

module.

• External status signals.

• TϋV Certified IEC 61508 SIL 3.

Description

The Power Supply Assembly consists of a Power Supply Chassis containing up to six Power

Supply Modules. The Chassis may be configured to distribute power in various

combinations. For example, a Chassis containing six Power Supply Modules may be set up

with three Modules providing triplicated power for Regent+Plus Input/Output (I/O)

assemblies and three Modules providing field power in a N+1 configuration. Alternatively,

the Chassis may be set up to provide separate dual 24 Vdc supplies for both a Trusted

System and associated field devices.

Power Supply Chassis

The Power Supply Chassis houses a maximum of six Power Supply Modules. It may be

mounted in a 19-inch rack or flush mounted on a panel. Table 1 identifies the available

types of Chassis.
