Switch Power (with FlexPower)
Efficient power management technology enables some FlexPower devices to include an internal power supply, called switch power (SP),
that briefly steps up to power sensors requiring 5, 10, or 15V power (ideally, 4–20 mA loop-powered sensors). When the switch power
output cycles on, the voltage is boosted to the voltage needed to power the sensor for a specific warmup time. This warmup time denotes
how long the sensor must be powered before a reliable reading can be taken. After the warmup time has passed, the input reads the
sensor, then the switch power shuts off to prolong battery life. The switch power voltage, warm-up time, and sample interval are configu-
rable parameters.
• To reduce power consumption and extend battery life, slower sample and reporting rates are used. Faster sample and report rates
can be configured, but this will decrease the battery’s life. For details, refer to the included table of DIP switch configurable parame-
ters.
• The FlexPower switched power management system can operate a FlexPower Node and a sensing device for up to five years on a
single lithium D cell.

FlexPower with Integrated Battery
A few FlexPower devices operate using a 3.6V lithium D cell battery integrated into the housing.
These integrated battery devices:
• Operate only from the battery and cannot use an external power supply,
• Are limited in the available I/O because of the limited connectivity, and
• Can only be powered from the integrated battery.

Banner’s FlexPower

Solar Supply Assembly can be used to
power up to two radio devices, including a FlexPower Node, a
FlexPower Gateway, or a data radio.
When used with a FlexPower Node and sensors, the Solar Assem-
bly supplies enough power to run most sensors at higher sample
and report rates than a single battery can reasonably support. Re-
chargeable batteries power the devices while the solar panel re-
charges the batteries.
