CAR2012TE series rectifier
Input: 85Vac to 264Vac; Output: 12 Vdc @ 2000W; 3.3Vdc or 5 Vdc @ 4A
The signal will be triggered for any state change whether a
‘warning’ or a ‘fault’, including the following conditions;
Block communications: When writing or reading more than
two bytes of data at a time BLOCK instructions for WRITE and
READ commands are used instead of the Standard
Instructions above to write or read any number of bytes
greater than two.

An example of the block_read instruction is the
Read_std_parameters (D0h) command. This ‘manufacturer
specific’ command returns STATUS and ALARM register data,
output voltage, output current, and internal temperature in a
single read string.
Standard instruction: Up to two bytes of data may follow an
instruction depending on the required data content. Analog
data is always transmitted as LSB followed by MSB. PEC is
optional and includes the address and data fields.

Linear Data Format The definition is identical to Part II of the
PMBus Specification. All standard PMBus values, with the
exception of output voltage related functions, are
represented by the linear format described below Output
voltage functions are represented by a 16 bit mantissa. The
value of the exponent for output voltage functions is listed in
the Vout_mode command.
