Electrical Specification
2.4.1.
Power Supply Voltage
The supply voltage is applied through the VCC pins (VCC) of the module connector. The COMe-bSL6 supports a power
supply input from 8.5 V to 20 V and operation in both single supply power supply mode and ATX power supply mode
The following table lists the power supply specifications.
Supply Voltage Range (VCC)
8.5 V to 20 V
Supply Voltage (VCC)
12 V
Standby Voltage
5V DC +/- 5 %
RTC
2.5 V to 3.47 V
5V Standby voltage is not mandatory for operation.
Extended temperature variants are validated for 12 V supply only.
2.4.2.
Power Supply Rise Time
The input voltage rise time is 0.1 ms to 20 ms from input voltage ≤10 % to nominal VCC. To comply with the ATX
specification there must be a smooth and continuous ramp of each DC input voltage from 10 % to 90 % of the DC input
voltage final set point.
2.4.3.
Power Supply Voltage Ripple
The maximum power supply voltage ripple is 100 mV peak-to-peak at 0 MHz to 20 MHz.
2.4.4.
Power Consumption
The maximum power consumption of the different COMe-bSL6 variants is 36 W to 60 W.
