Emerson Network Power Enhances Intelligent Power Supply Connectivity

Emerson Network Power announced the addition of three new case adapter modules for its iMP and iVS Series of digitally configurable ac-dc switching power supplies. The adapters – which enable both USB and Controller Area Network (CAN)/RS485bus connectivity – are said to provide a complete interface between the host device and the I²C bus with a simple command set, enabling the highest levels of configuration flexibility. The adapters also enable Emerson’s intelligent standard power supplies to be used in a host of new ruggedized applications, including automotive networks, industrial networks, medical equipment and building automation systems – many of which interface exclusively via CANbus architectures.

Designed for use with iVS/iMP digitally configurable power supplies, the CAN/RS485 to I²C interface adapter modules connect with CANbus architectures through CaseRx/CaseTx interfaces found on all iVS and iMP cases. The modules communicate with onboard I²C Bus via MODbus Protocol for RS485 Bus and modified MODbus for CANbus. The USB to I²C interface adapter module for the iVS digitally configurable power supply connects to a standard USB port found on most PCs and provides bidirectional communication with devices using theI²C protocol.

All iVS/iMP interface adapters are internally-powered when connected to the case’s 5VSB port and include an on board socket for reprogramming the interface adapter controller. All modules are also Restriction of Hazardous Substances (RoHS) compliant.

The interface adapters are currently available and start at $6 in OEM quantities, depending on module selected.
