PIN / CONTROL FUNCTIONS
+In / -In DC Voltage Ports
VH – Auxiliary Voltage
Brick®
The VI
maximum input voltage should not be exceeded. PRMs have
internal over / undervoltage lockout functions that prevent operation
outside of the specified input range. PRMs will turn on when the input
voltage rises above its undervoltage lockout. If the input voltage exceeds
the overvoltage lockout, PRMs will shut down until the overvoltage fault
clears. PC will toggle indicating an out of bounds condition.
VH is a gated (e.g. mirrors PC), non-isolated, nominally 9 Volt, regulated
DC voltage (see “Auxiliary Pins” specifications, on Page 7) that is
referenced to SG. VH may be used to power external circuitry having a
total current consumption of no more than 5 mA under either transient or
steady state conditons including turn-on.
SC – Secondary Control
+Out / -Out Factorized Voltage Output Ports
These ports provide the Factorized Bus voltage output. The –Out port is
connected internally to the –In port through a current sense resistor. The
PRM has a maximum power and a maximum current rating and is
protected if either rating is exceeded. Do not short –Out to –In.
The load voltage may be controlled by connecting a resistor or voltage
source to the SC port referenced to SG. The slew rate of the output
voltage may be controlled by controlling the rate-of-rise of the voltage at
the SC port (e.g., to limit inrush current into a capacitive load).
SG – Signal Ground
VC – VTM Control
The VTM Control (VC) port supplies an initial VCC voltage to downstream
VTMs, enabling the VTMs and synchronizing the rise of the VTM output
voltage to that of the PRM. The VC port also provides feedback to the
PRM to compensate for voltage drop due to the VTM output resistance.
The PRM’s VC port should be connected to the VTM VC port. A PRM VC
port can drive a maximum of two (2) VTM VC ports.
PC – Primary Control
The PRM voltage output is enabled when the PC pin is open circuit
(floating). To disable the PRM output voltage, the PC pin is pulled low.
Open collector optocouplers, transistors, or relays can be used to control
the PC pin. When using multiple PRMs in a high power array, the PC ports
must be tied together to synchronize their turn on. During an abnormal
condition the PC pin will pulse (Fig.11) as the PRM initiates a restart cycle.
This will continue until the abnormal condition is rectified. The PC should
not be used as an auxiliary voltage supply, nor should it be switched at a
rate greater than 1 Hz.
This port provides a low inductance Kelvin connection to –In and should be
used as reference for the OS, CD, SC,VH and IL ports.
OS – Output Set
The application-specific value of the Factorized Bus voltage (Vf) is set by
connecting a resistor between OS and SG. Resistor value selection is shown
in Table 1 on Page 9, and described on Page 10. If no resistor is connected,
the PRM output will be approximately one volt. If set resistor is not collocated with the PRM, a local bypass capacitor of ~200 pF may be required.
CD – Compensation Device
Adaptive Loop control is configured by connecting an external resistor
between the CD port and SG. Selection of an appropriate resistor value
(see Equation 2 on Page 10 and Table 1 on Page 9) configures the PRM to
compensate for voltage drops in the equivalent output resistance of the
VTM and the PRM-VTM distribution bus. If no resistor is connected to CD,
the PRM will be in Local Loop mode and will regulate the
+Out / –Out voltage to a fixed value.
TM – Factory Use Only
IL – Current Limit Adjust
The PRM has a preset, maximum, current limit set point. The IL port may
be used to reduce the current limit set point to a lower value. See “adjusting current limits” on page 11.
PR – Parallel Port
The PR port signal, which is proportional to the PRM output power,
supports current sharing of two PRMs. To enable current sharing, PR ports
should be interconnected. Steps should be taken to minimize coupling
noise into the interconnecting bus. Terminate this port with a 10 k
equivalent resistance to SG, e.g. 10 k for a single PRM, 20 k each for 2
PRMs in parallel, 30 k each for 3 PRMs in parallel etc.. Please consult Vicor
Applications Engineering regarding additional considerations when
paralleling more than two PRMs.

APPLICATION INFORMATION
Overview of Adaptive Loop Compensation
The VI Brick’s bi-directional VC port :
Adaptive Loop compensation, illustrated in Figure 15, contributes to the
bandwidth and speed advantage of Factorized Power. The PRM monitors its output current and automatically adjusts its output voltage to
compensate for the voltage drop in the output resistance of the VTM®.
ROS sets the desired value of the VTM output voltage, Vout; RCD is set to
a value that compensates for the output resistance of the VTM (which,
ideally, is located at the point of load). For selection of ROS and RCD,
refer to Table 1 below or Page 10.

After setting the output voltage from the procedure above the output

APPLICATION NOTES
OVP – Overvoltage Protection
Adjusting Current Limit
The output Overvoltage Protection set point of the PR045A480T032FP 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.
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.
As shown in Figure 17, the PR045A480T032FP 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.

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. Please see
vicorpower.com for agency approvals and fusing conditions.
Factorized Bus Voltage (Vf)
Product Safety Considerations
Figure 17 — PR045A480T032FP rating based on Factorized Bus voltage
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.
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.
If the input of the PRM is connected to a centralized DC power system
where the working or float voltage is above SELV, but less than or equal to
75 V, the input and output voltage of the PRM should be classified as a
TNV-2 circuit and spaced 1.3 mm from SELV circuitry or accessible
conductive parts according to the requirements of UL60950-1,
CSA 22.2 60950-1, EN60950-1, and IEC60950-1.
