BLUEstreak Series
BLUEstreak is Unipower Corporation’s new generation high density hotswappable, modular Front-Ends and Rectifiers producing up to 2000 watts output power. There are 6 standard models with different output voltages and power levels. The modules are ultra-compact with power density up to 24 watts per cubic inch. The modules have automatic load sharing and active output ORing circuit so they can be hot-swapped while the system is
operating.
Using PMBus compliant serial communications, status and control data can be passed between a host system or power management unit and the module.
Front panel mounted LEDs indicate various status or fault conditions and +5V & 12V standby outputs are included.
Operating temperature range is -40°C to +70°C.

PUSH BUTTONS:
The two push buttons located just above the LEDs can be used to adjust
the
output voltage when the output is enabled. These buttons are labelled
V▲ and
V▼. Short presses for a fraction of a second adjust the output
voltage at the
output voltage setting resolution. If the button is held down, the rate
of change
increases to around 1V/s after 10s. If both buttons are pressed together,
the
button adjust is cleared to zero. The PMBus can read the button adjust
value
and also clear the value. The PMBus can also be used to enable or disable
the buttons.
PMBus SPECIFICATIONS:
PHYSICAL ADDRESSING
The module responds to a single PMBus address. Multiple units can
be used together on a single bus by configuring each module with a
different physical address. Five of the address bits are brought out
on
the module connector and these may be either tied high (to 5VSB) or
low (to SBReturn) to configure the address. The other two bits GA5
and GA4 are internally set to low and high respectively. The table
below summarizes the addressing capability. This gives the module
32 possible addresses, in two banks of 16.

FAULT REPORTING
faults are reported using the SMBALERT signal. This allows the bus
master to determine if a fault has occurred so that it can quickly determine
which module has a fault.
Packet Error Checking (PEC)
The Bluestreak PMBus implementation supports
packet error checking. The user may configure messages with an additional
CRC check byte at the end. Any errors will cause an alert enabling
the master to resend the message. Messages received from the module
also have a PEC byte appended to the end. This byte may be read if
required or only
the message bytes may be read.
