Standard Features
1.
Type of Power Conversion Circuit: High frequency.
2.
Input Protection:
a)
Input Over/Under Voltage Protection: The rectifier will shut down at low or high voltage input;
based on the following voltage levels:
Low Voltage Disable Point: 80 VAC, ±5 V; hysteresis is at least 15 VAC for restart.
High Voltage Disable Point: 305 VAC, ±5 V; hysteresis is at least 10 VAC for restart.
b)
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 500 W.
At input voltage of 176 VAC with output >48 VDC, maximum output power is 1000 W.
3.
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
20.83 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 17 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 until the LEDs on the rectifier extinguish, 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.
