POWER CONNECTOR
Voltage Limit
Characteristics
Maximum input voltage
Minimum input voltage
CURRENT LIMIT
The Power + signal will conform to the following current requirements:
Characteristics
Typically average current consumption for Power +
Typically peak current consumption for Power +
Typically peak power consumption for Power +
It is recommended to use a Class II double insulated power supply, or a power limited external
battery. The source should always be limited to a output power of no more than 100 watts in
total.
