Vertiv™ NetSure™ IPE Series Rectifier Installation and User Manual

High Voltage Disable Point: 305 VAC, ±5 V; hysteresis is at least 10 VAC for restart.

Between
85
VAC
and
176
VAC
the
output
power
will
be
derated
linearly
based
on
the
input
voltage
as
follows:
At input voltage of 85 VAC with output >48 VDC, maximum output power is 1275 W.
At input voltage of 176 VAC with output >48 VDC, maximum output power is 2000 W.

Output Protection:
a)
Overload / Reverse Current: The rectifier has a fuse wire in the negative output DC bus. This fuse is not customer
replaceable.
b)
Current Limiting: The rectifier has a current limit function. The current limit point is factory set at 41.7 A. The current
limit accuracy is ±1.5 A when the output voltage ranges from 42 VDC to 58 VDC.
c)
Advanced Current Limit Function: The rectifier has an advanced Current Limit Function. When a short circuit occurs
at the rectifier output terminals, the rectifier will keep its output current at a constant value (factory set at 34.5 A). This
function effectively protects the rectifier and the equipment connected to the rectifier. When the short circuit fault is
cleared, the rectifier will automatically restore back to normal operation.
d)
High Voltage Shutdown:
•
Fixed Control: If rectifier output voltage exceeds a factory set value of 59.5 VDC and the rectifier is delivering more
than 10% of its rated current, the rectifier shuts down. (The restart hysteresis is 0.5 V ±0.2 V.)
The rectifier then restarts and a HVSD restart timer starts (factory set at 5 minutes). If output voltage again
exceeds the high voltage shutdown value before the HVSD restart timer expires, the rectifier shuts down and locks
out. Manual restart is then required (by turning power to the rectifier off, waiting 30 seconds or more, then turning
power to the rectifier on). If the rectifier does not experience a high voltage condition before the HVSD restart
timer expires, the restart circuit is reset.
If two or more rectifiers are paralleled, only the rectifier causing the high voltage condition shuts down.
•
Backup: If rectifier output voltage exceeds 59.5 VDC ±0.5 V (non-adjustable), the rectifier shuts down. The
rectifier then restarts and a HVSD restart timer starts (factory set at 5 minutes). If output voltage again exceeds
the high voltage shutdown value before the HVSD restart timer expires, the rectifier shuts down and locks out.
Manual restart is then required (by turning power to the rectifier off, waiting 30 seconds or more, then turning
power to the rectifier on).
4.
Over-Temperature Protection: The rectifier provides over temperature protection by derating output power and recovers
automatically.
5.
Active Load Sharing: The rectifier uses advanced digital active load sharing technology that maintains balancing to within 5%
of rated current.
6.
Paralleling: Up to three (3) rectifiers can be connected in parallel in one system. Do not exceed the load rating of a single
rectifier.
7.
Monitoring Function: The rectifier has a built-in advanced DSP that monitors and controls the operation of the rectifier.
CAUTION!
Double pole/neutral fusing.
