19” Subracks & Redundant Systems
Front View
Description
In addition to a complete range of individual
power supplies we are able to offer a ‘total
solution’ to your power requirements.
Subracks can be configured as 3U, 6U or 9U and
multiples thereof, allowing any mix of units
including ‘hot swap’ redundant systems.
The wide range of options available include input
fuses, circuit breakers, decoupling diodes, RFI
filters, front panels and full system wiring.
Outputs are via DIN rail screw terminals and are
configured to customers requirements to
incorporate DC OK relay contacts, input and
output connections and any other options.

Example
The photographs show a typical system
containing a C624-DD.DR which could be
configured with another unit to provide a
dual redundant system.
i.e. Specification could be:
DC Input: 18-36 V
DC Output: 24 V @ 18 A, dual redundant
Each unit is rated at 18 Amps and is connected
in parallel via decoupling diodes and set up to
current share. In the event of a psu failure the DC
OK alarm relay trips, the failed psu can be
identified by its front panel LED and the psu
replaced without power shut down ie. ‘Hot Swap’.
A full system schematic is provided with each
system as shown below, the size and orientation
of connectors can be specified by the customer.
