Individual maximum current for 12 V and SW12 output terminals

Regulated 12 V output. System power output current limits may override one or more of these individual limits. These outputs are disabled when operating on only USB power.

  • Voltage Output: Regulated 12 V output (±5%)
  • Current Limit: 2000 mA

5 V fixed output

Regulated 5 V output. Supply is shared between the 5V terminal and CS I/O DB9 5 V output.

  • Voltage Output: Regulated 5 V output (±5%)
  • Current Limit: 230 mA

Control port as power output

Operating at the current limit is OK if voltage fluctuation can be tolerated. Drive capacity is determined by the logic level of the VDC supply and the output resistance (Ro) of the C terminal. It is expressed as: Vo = 5 V – (Ro • Io), where Vo is the drive limit, and Io is the current required by the external device. For example: at the maximum current limit of 10 mA on C1 the voltage level would reduce from 5 V to 3.5 V.

  • C Terminals:

    • Output Resistance (Ro): 150 Ω
    • 5 V Logic Level Drive Capacity: 10 mA @ 3.5 VDC; Vo = 5 V - (150 Ω •Io)
    • 3.3 V Logic Level Drive Capacity: 10 mA @ 1.8 VDC; Vo = 3.3 V - (150 Ω •Io)

CS I/O pin 1: 5 V fixed output

Regulated 5 V output. Supply is shared between the 5V terminal and CS I/O DB9 5 V output.

  • Voltage Output: Regulated 5 V output (±5%)
  • Current Limit: 230 mA

CS I/O pin 8: 12 V switched output

Regulated 12 V output. Power output shared with system power output. This output is disabled when operating on only USB power.

  • Voltage Output: Regulated 12 V output (±5%)
  • Current Limit: 800 mA
