RapidPro Power Unit

Flexible power stage unit

The RapidPro Power Unit, in conjunction with the standard PS modules or customer-specific modules, lets you adapt many different types of actuators (drives, injectors, valves, relays, ohmic loads, etc.) to specific prototyping systems.

Key Benefits

The RapidPro Power Unit is based on the same advanced architecture as the RapidPro SC Unit. The main difference is that the power unit is designed to support high-current signals for driving actuators. The carrier board offers space for up to six power stage modules, with or without current feedback. Each RapidPro Power Unit can have up to 48 power driver channels. The whole RapidPro Power Unit can be switched on or off from dSPACE prototyping systems via a remote control input, or all outputs can be deactivated via an enable/disable input. dSPACE‘s ConfigurationDesk provides easy configuration of the unit and extensive diagnostics handling.
