VB-8034/8054 DC Power Supply Connections and LEDs
|
Caution Exceeding the maximum output ratings, which are listed in the NI VirtualBench Specifications, can damage the device and the computer. National Instruments is not liable for any damage resulting from such signal connections. |
The DC power supply has six LEDs that correlate to the three available voltages available on the connector.
Connections and LEDs
|
|
||
| 1 +6V CV and CC LEDs | 6 Channel +25V (0 to +25 V) | |
| 2 Channel +6V (0 to +6 V) | 7 Common Floating GND | |
| 3 GND | 8 -25V CV and CC LEDs | |
| 4 GND | 9 Channel -25V (0 to -25 V) | |
| 5 +25V CV and CC LEDs | ||
 |
Note The +25 V and -25 V channels are bank isolated from ground but not from each other. |
LED Patterns
| LED | Color | Description |
|---|---|---|
| +6 CV | Blue | Constant 0 to +6 V voltage |
| +6 CC | Orange | Constant 0 to 3 A current |
| +25 CV | Blue | Constant 0 to +25 V voltage |
| +25 CC | Orange | Constant 0 to 1 A current |
| -25 CV | Blue | Constant 0 to -25 V voltage |
| -25 CC | Orange | Constant 0 to 1 A current |
|
Note The color of the LED matches the color of the CV and CC indicators in the VirtualBench application, blue and orange respectively. |
VirtualBench has three, single-quadrant DC power supply channels. Each channel on the DC power supply can operate only within one quadrant (channels +6V and +25V operate only within Quadrant I, and channel -25V operates only within Quadrant III).
| DC Power Supply Channel | Quadrant Operation |
|---|---|
| +6 V, +3 A | 
|
| +25 V, +1 A -25 V, -1 A |
