Power output specifications
System power out limits (when powered with 12 VDC):
Temperature (°C) | Current Limit1 (A) |
---|---|
–40° | 5.8 |
20° | 3.7 |
70° | 2.0 |
VX: Two independently configurable voltage terminals (VX1-VX2). VX outputs are produced by a 12-bit DAC Digital to analog conversion. The process that translates digital voltage levels to analog values..
CR300 series data loggers are not capable of applying reverse excitation. Set the RevEx
parameter of all bridge measurement instructions to False
.
- Range: 150 to 5000 mV
- Resolution: 1.6 mV
- Maximum Source Current: 50 mA total, concurrently or independently.
See also Voltage measurements.
SW12V: Provides unregulated 12 VDC power with voltage equal to BAT+ input voltage. SW12V is disabled when operating on USB power only. A thermal fuse regulates current sourcing.
- Thermal Fuse Hold Current (Overload causes voltage drop. Disconnect and let cool to reset. Operate at limit if the application can tolerate some fluctuation.):
- 1200 mA @ -40 °C
- 1100 mA @ 20 °C
- 830 mA @ 70 °C
