Trumouse Lite: Power Supply and Electrical Specifications

External Power Inputs

Table: External power inputs

Component	Input	Connector	Power source
Reader Array (RFID floor platform)	DC 5 V	DC connector, 2 per block	External low-ripple DC supply
Top Panel (White Light, Infrared Light, environmental sensor, Light Control Module and Exhaust Fan)	DC 24 V	DC connector	External DC supply
Industrial Camera	External 12 V / 24 V DC supply, or powered together with the Top Panel lighting	6-pin P7 connector	External DC supply
Switch	As specified by its manufacturer	Mains plug	Independent power supply
Compute Unit	As specified by its manufacturer	Mains plug	Independent power supply

The Reader Array must be powered from a low-ripple DC supply. All external power supplies and the switch are certified commercial products. See Figure “Trumouse Lite interface locations (viewed from the right front)” for the location of the power connectors.

Power Supply of Each Part

The Reader Array (RFID floor platform) is powered at 5 V DC. The Top Panel (White Light, Infrared Light, environmental sensor, Light Control Module and Exhaust Fan) is powered at 24 V DC. Industrial Camera power supply: External 12 V / 24 V DC supply, or powered together with the Top Panel lighting. The Compute Unit has its own power supply. All DC supplies in the system are 24 V or lower.

System Power Consumption

Table: Estimated power consumption

Subsystem	Power supply	Estimated power (W)
Reader Array (RFID floor platform)	5 V DC	25
Infrared Lights	24 V DC	24
White Light	24 V DC	10
Industrial Camera	12 V or 24 V DC	1.8
Environmental Sensor	24 V DC	3
Total (excluding the Compute Unit)		63.8

The power figures are estimates and exclude the Compute Unit. The Industrial Camera uses the typical power consumption from its datasheet; the other figures are approximate.
