Control and Telemetry Interface
The WaveSculptor receives commands, and transmits telemetry values, using a CAN bus connection. No other interface is provided. Low-voltage DC power must be provided along the CAN bus cable to operate the control electronics of the WaveSculptor.
| Supply | Units | Notes: | |
|---|---|---|---|
| CAN bus supply voltage minimum: | 9 | V | Note 1 |
| CAN bus supply voltage maximum: | 15 | V | Note 1 |
| CAN bus supply voltage nominal: | 13.8 | V | Note 1 |
| CAN bus supply power maximum: | 20 | W | |
| CAN bus data rate maximum: | 1000 | kbps | Note 2 |
| CAN bus isolation: | 1000 | V | Note 3 |
Notes:
-
Prohelion recommends providing the CAN bus supply with 13.8V, using a DC/DC converter and a backup lead-acid battery. This arrangement, when properly implemented, gives a supply that can tolerate failures and still operate the controller successfully for a short period of time. ↩↩↩
-
The data rate used for CAN bus activity is set during configuration and setup of the controller. Factory default for all Prohelion devices is 500 kbits per second. ↩
-
The CAN bus data connection and power supply are isolated from the high-power DC bus to this continuous voltage rating. Please refer to the isolation section in the User Manual regarding recommended earthing and connection practices. ↩
