Application Information (continued)
VI Chip Pre-Regulator Module
OVP – Overvoltage Protection
The output Overvoltage Protection set point of the P045F048T32AL is
factory preset for 56 V. If this threshold is exceeded the output shuts
down and a restart sequence is initiated, also indicated by PC pulsing.
If the condition that causes OVP is still present, the unit will again shut
down. This cycle will be repeated until the fault condition is removed.
The OVP set point may be set at the factory to meet unique high
voltage requirements.
PRM Output Power Versus VTM Output Power
As shown in Figure 17, the P045F048T32AL is rated to deliver 6.66 A
maximum, when it is delivering an output voltage in the range from
26 V to 48 V, and 320 W, maximum, when delivering an output
voltage in the range from 48 V to 55 V. When configuring a PRM for
use with a specific VTM, refer to the appropriate VTM data sheet. The
VTM input power can be calculated by dividing the VTM output power
by the VTM efficiency (available from the VTM data sheet). The input
power required by the VTM should not exceed the output power rating
of the PRM.
The Factorized Bus voltage should not exceed an absolute limit of 55 V,
including steady state, ripple and transient conditions. Exceeding this
limit may cause the internal OVP set point to be exceeded.
Parallel Considerations
The PR port is used to connect two PRMs in parallel to form a higher
power array. When configuring arrays, PR port interconnection
terminating impedance is 10 k to SG. See note Page 8 and refer to
Application Note AN002. Additionally one PRM should be designated
as the master while all other PRMs are set as slaves by shorting their
SC pin to SG. The PC pins must be directly connected (no diodes) to
assure a uniform start up sequence. Consult Vicor applications
engineering for applications requiring more than two PRMs.
Adjusting Current Limit
The current limit can be lowered by placing an external resistor
between the IL and SG ports (see Figure 18 for resistor values). With
the IL port open-circuit, the current limit is preset to be within the
range specified in the output specifications table on Page 4.
Input Fuse Recommendations
A fuse should be incorporated at the input to the PRM, in series with
the +In port. A fast acting fuse, NANO2 FUSE 451/453 Series 10 A
125 V, or equivalent, may be required to meet certain safety agency
Conditions of Acceptability. Always ascertain and observe the safety,
regulatory, or other agency specifications that apply to your specific
application.
Product Safety Considerations
If the input of the PRM is connected to SELV or ELV circuits, the output
of the PRM can be considered SELV or ELV respectively.
