Power Supply Requirements


UL294 Listed Power-Limited Power Supply capable of 4 hours standby power providing 12VDC or 24VDC
Note: The LED on the cover of the VLB is a power indicator. However it is not an AC indicator as the UL Listed
power-limited power supply capable of 4 hour standby power could be providing the VLB with power even if AC
power has been removed.
The lite blue controller is designed to only provide power the power supply to readers attached to the two
onboard reader interfaces. Additional devices must be powered independently from the lite blue controller. If a
single power supply is used, it must be large enough to power the lite blue controller and all attached devices.
Make sure that the total power requirements for all devices does not exceed the output of the power supply(s) in
use (see specific device chapters for power requirements). If not enough power is being supplied, the devices and
the lite blue controller will not work correctly.
