The default method of digital communication shall utilize I2C hardware capable of operation at a minimum of 100 kHz clock (SCL)

frequency. A mandatory feature of this module is that should either the module be disconnected from the incoming AC source

(inserted in to a slot in an unpowered state); the module input fuse(s) fail; or the internal auxiliary supply (which derives the VCC of

the I2C equipped device) fail, then any line associated with the I2C bus (SCL; SDA) should be disconnected (effectively tri-stated)

from the I2C bus to prevent erroneous operation that may result from this unpowered condition. All I2C lines shall be “clean” and

free from excessive spikes and common mode noise and comply with the requirements of the generic standard which defines I2C

logic levels.

The I2C hardware should conform to the requirements of the NXP (formerly Philips Semiconductor) Standard: UM10204 I2C Bus

Specification and User Manual; Rev 0.3; 19 June 2007.

The rectifier shall be capable of processing commands to monitor & control the rectifier via the digital bus by use of the following

protocols:

•

CUI’s “standard” protocol – this shall be considered the “default” that shall be offered as a standard.

•

The PMBus® (Power Management Bus) Protocol – this shall be considered the “optional” offering.
