ICS Triplex T8231C Power Pack

ICS Triplex T8231C Power Pack

Functional Description

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 They are secured

using a physical latch on the front of the Power Pack which is pushed up to release or connect the Power

Pack into the Power Shelf.

Features and benefits

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.

Overcurrent Protection

The over-current protection limits the output current in the event of an overload. There are two overload

circumstances:

• If the load is increased steadily a single Power Pack compensates by derating the voltage, hence at 40 A

(the specification limit) the voltage is derated to 18.75 V. This derated voltage is on the limit of the Trusted

System Modules' specification.

• If 24 V is maintained over a rapid current rise, the over-current protection will trip the power supply when

35 A is reached. This rapid increase is more typical of a fault situation in a system.
