FEATURES DESCRIPTIONS
Over-Power Protection
The modules include an internal output over-power
protection circuit, which will endure power limiting for an
unlimited duration during output overload. If the output
current exceeds the OCP set points, the modules will
automatically shut down (hiccup mode).
The modules will try to restart after shutdown. If the
overload condition still exists, the modules will shut down
again. This restart trial will continue until the overload
condition is corrected.
The OCP function could be changed via PMBUS. The
command related to OCP function are
IOUT_OC_WARN_LIMIT, IOUT_OC_FAULT_LIMIT and
IOUT_OC_ FAULT _RESPONSE.
Over-Temperature Protection
The over-temperature protection consists of circuitry that
provides protection from thermal damage. If the
temperature exceeds the over-temperature threshold, the
modules will shut down, and enter the auto-restart mode.
For auto-restart mode, the module will monitor the
module temperature after shutdown. Once the
temperature of module is decreased by an OTP
hysteresis, the module will restart.
The OTP function could be changed via PMBUS. The
command related to OTP function are OT _WARN_LIMIT,
OT_FAULT_LIMIT and OT_FAULT _RESPONSE.
Input Under Voltage Lockout
When Vin exceeds Vin turn on threshold, the module
output is enabled, when Vin falls below Vin turn off
threshold, the module output is disabled. Vin turn on
threshold and Vin turn off threshold can be reconfigured
via the PMBus interface.
The Vin UVP function could be changed via PMBUS. The
command related to Vin UVP function are VIN_ON and
VIN_OFF.
Output Overvoltage Protection
The module can detect and respond to output
overvoltage conditions. If the overvoltage condition
causes the output voltage to rise above the limit in the
Specifications Table, the module will shut down.
The modules will try to restart after shutdown. If fault
condition still exists, the modules will shut down again.
This restart trial will continue until the fault condition is
corrected.
The Vo OVP function could be changed via PMBUS.
The command related to Vo OVP function are
VOUT_OV_WARN_LIMIT, VOUT_OV_FAULT_LIMIT
and VOUT_OV_ FAULT _RESPONSE.
Input Over Voltage Lockout
The module can detect and respond to input
overvoltage conditions. If the input voltage rises above
the limit in the Specifications Table, the module will shut
down.
The module is factory default configured for auto-restart
operation. The auto-restart feature continually monitors
the input voltage and will restart the module when the
level falls 6V below the Input OVP level.
The Vin OVP function could be changed via PMBUS.
The command related to Vin OVP function are
VIN_OV_FAULT_LIMIT and
VIN_OV_FAULT_RESPONSE
Remote ON/OFF (ENABLE)
The remote ON/OFF (ENABLE) feature on the module
is negative logic. The low logic turns the modules on.
And the high logic, or floating, turns the modules off.
Remote ON/OFF (ENABLE) can be controlled by an
external switch between the on/off terminal and the
Vin(-) terminal. The switch can be an open collector or
open drain.
