Description: The Circadian® Hot Swap module is the Heart of the system. It is
designed to regulate Hot Swapping i.e. 24-7 power and to be completely flexible
from an input and output configuration and to provide essential clear information
to the nurse.
Intended Use: part of the Circadian® system, the Hot Swap
module is cart mounted, ideally out of sight in the Tray with
only the LCD info interface visible, or for external use in a
Housing – see picture.
Benefits: On the input side, the module can take power from
up to 4 Batteries (plus power Supplies). A 2 battery version is
more typical to ensure Hot Swapping. The Raw battery Voltage is then regulated for Output by an up
to 98% efficient DC/DC converter. Standard voltages are 14V, 19V or 24V, however other voltages
can be set on request. A 2nd piggyback DC/DC converter can be added at any time. This allows a
flexible DC/DC system and avoids the potential 30% loss of the commonly used DC-AC-DC systems.
However the inverter option is still open using the 14V output. For communication the Circadian®
system has two outputs: The colour LCD displayed above is independent and gives the Nurse a visual
remaining runtime before a Hot Swap is required in hours and minutes. It also shows how many
batteries are in use and their comparative capacity status and warns the nurse if the Cart is plugged
into an electrical outlet. A further communication option is the USB communication cable. This can
feed the cart LED display or a PC software with standard battery info. This uses CAN-Bus which is a
significant improvement on the standard SM-BUS protocol that is so often vulnerable to
Technical specs: (Optional as PCB or housed version). Specs below apply to housed version
Weight: (400g) Height 4.3cm Width: 16.4 cm Depth: 10.4cm /13.3cm incl. screw fixation plate.
All connector block on PCB are plug-in connectors. Fast set up. 3 Pin output. Central pin carries a
sense V signal in the 19V setting to provide laptops with Power supply in signal.
Max Load. Total max load depends on total amount of batteries. One Hot swap PCB battery can
deliver 150W (max 175). 2 Hot Swap PCBs can deliver max 300W. Batteries have to be equal to share
Display is 2.8 inch colour LCD Display. Updating remaining runtime every 5 seconds.
