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 1000 W.
At input voltage of 176 VAC with output >48 VDC, maximum output power is 2000 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 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.)
