24 Vdc Power-Supply Terminal Block
The Micrologic 5/6 trip unit display is operational when current is flowing through the circuit breaker. To
power the Micrologic 5/6 trip unit when the trip unit is not connected to an FDM121 or to the
communication network, a 24 Vdc power-supply terminal block can be installed only on Micrologic 5/6
trip units. When used, it excludes connection of an NSX cord.
External 24 Vdc Power-Supply Module
An external 24 Vdc power supply is required for installation in a communication network, whatever the
type of trip unit.
On installations without a communication network, the power supply is available as an option for
Micrologic 5/6 trip units in order to:
•
modify settings when the circuit breaker is open
•
display measurements when the current flowing through the circuit breaker is low (15 to 50 A
depending on the rating)
•
maintain the display of the cause of tripping and interrupted current.
A single external 24 Vdc supply may be used for the entire network, depending on the number of
devices in the communication network. The required characteristics are:
•
output voltage: 24 Vdc ± 5%
•
ripple: ± 1%
To determine the required output current of the 24 Vdc power supply, it is necessary to sum up the
currents consumed by the different loads supplied.
