TrustedTM Power System T823X 3. Power Shelf Specification The Power Shelf is designed to operate as a key element in a complete distributed Power System. This Power Shelf can house up to three Power Packs, provides physical protection and a number of alarm and control features. The Power Shelf can supply up to 1500W of N+1 redundant power or up to 2250W of total power depending on configuration of Power Packs. Four stacked Power Shelves can provide up to 9,000W total power.
TrustedTM Power System T823X 3.1. Input Connector The Power Shelf can be used with any standard global line voltages. The standard AC input connection to the Power Shelf is through three clip retained IEC320 type connectors rated at 10A / 250Vac in Europe/Asia and 15A /120Vac in North America. 3.2. Output Connector The Power Shelf has two terminal blocks for DC output (each with three M4 screws). The V+ and Vare floating with respect to frame GND, either of which can be connected to GND as required. 3.3.
TrustedTM Power System T823X 3.4. Interface Connector The Power Shelf has an optional DSB, 25-pin, female interface connector on the back. The Power System can be monitored and controlled through this interface, by a Power Controller, using a Power Shelf Interconnect. AC and DC fail alarms are available from a separate connector on the Power Port.

TrustedTM Power System T823X 4. Power Pack Specification The Power Pack is specifically designed to operate as an integral part of a complete distributed Power System. A full complement of protection, alarm and control features has been incorporated into the Power Pack to provide versatility for use in many applications. Power Packs can be inserted and removed when live, allowing ‘hot-swap’ of Power Packs (see section 4.7).
TrustedTM Power System T823X 4.1. Power Pack Features 4.1.1. Indicators The Power Pack has two indicators on the front: AC OK: The LED is green if the input voltage is within limits. PWR OK: The LED is green if the Power Pack is healthy and within operating limits. If a fault occurs with the power supply or a fan, the LED is amber. Failure of an internal power pack fan results in shutdown of the output of the power pack. 4.1.2.

TrustedTM Power System T823X 5. Power Port 5.1. General Description The Power Port is a supplied accessory and is fitted onto the rear of the Power Shelf. It converts alarm signals produced by the Power Packs and Power Shelf into volt-free alarm contacts for use by the system and enables hot replacement of Power Packs. It consists of a pcb fitted with connectors, relays and miscellaneous electronic components. The shape and size of the Power Port is shown in Figure 11.
TrustedTM Power System T823X 5.2. Circuit Description The circuit is split into four functional sections: supply, dc alarms, ac alarms and jumpers. 5.2.1. Supply The 24V supply is connected to CON3 pins 1 & 6. The supply should be fused close to its source, using a 500mA F rated fuse. It is nevertheless protected by a non-replaceable fuse on the Power Port. The 24V is regulated down to 5V with decoupling provided. The 5V+ is used to supply the low voltage electronics.
TrustedTM Power System T823X 5.2.4. Jumpers There are three jumpers, J1, J2 and J3. 2 J1 and J2 set the Power Shelf address lines for the I C control bus. With J1 and J2 fitted the Pack addresses are 1, 2 and 3, which is the default. Other addresses may be set by removing one or both of J1 and J2, up to 4 shelves worth (or 12 Power Packs).
TrustedTM Power System T823X 5.3. Mechanical 5.3.1. Pin-out CON 1, CON 2 CON 1 on the Power Port connects to the Power Shelf. The pin-out details are shown in Table 2. CON 2 is used to connect to other Power Shelves to current share or to connect to a Power Controller.

TrustedTM Power System T823X 6. Power Controller The Power Controller is designed to control and monitor the 19” rack mount 1U high Power Shelf units. It is used to address each Power Pack in turn and adjust the respective Power Pack voltage. The Power Controller is a digital system and communicates with the Power Packs by means of a TC323 Power Shelf Interconnect ribbon cable, via the Power Port. The shelf addresses are set using jumpers on the Power Port, as described in paragraph 5.2.4.
TrustedTM Power System T823X 6.1. Power up sequence When a power controller is connected to more than one power shelf, power shelves should have their supplies applied in turn, e.g. power up first shelf (idents 1-3), followed by shelf two (idents 4-6) etc. This ensures that the power pack addresses are not duplicated.
TrustedTM Power System T823X 7. Power Shield If a Power Shelf is not fully populated, Power Shields are used to cover unused spare slots. 8. Power Shelf Interconnect A ribbon cable is required to connect Power Shelves together in order to current share, or to connect shelves to a Power Controller. The supplied ribbon cable has 5 connectors, to allow the maximum of 4 shelves and a Power Controller to be connected.
