Standard Features
Type of Power Conversion Circuit: High frequency.
Constant Voltage Mode: For any initial output voltage setting from 47 to 58 volts,
output voltage remains constant regardless of load. This is the normal operating
condition, in which loads are being supplied and batteries are float charged.
Rectifiers operate in the Constant Voltage Mode unless load increases to the point
where the product of load current and output voltage is approximately 3200W or
3500W (depending on Rectifier model).
Constant Power Mode: As load increases above approximately 3200W or 3500W
(depending on Rectifier model) (non-adjustable), output current continues to
increase, but output voltage decreases as required to maintain constant output
power. Rectifiers operate in the Constant Power Mode unless load continues to
increase to the point where the current limit setting is reached.
Constant Current Mode: If load increases to the current limit setting, output voltage
decreases linearly to maintain output current at the current limit setting.
Input Protection:
a) Fuse: On the input, two UL recognized fuses are used, not user-replaceable.
b) Input Voltage Protection: Operating range is 85-290Vac. Derating from 85Vac
to 176Vac. Withstand 415Vac input w/o damage.
1) The Rectifier will shut down at low or high voltage input; Low voltage disable
point: 80V±3V; Hysteresis at least 15 VAC for restart. High voltage disable
point: 295V±5V; Hysteresis at least 10 VAC for restart.
2) Between 85V and 176V the output power will be derated linearly according to
input voltage per Figure 4, Figure 5, and Figure 6.
3) Over Voltage Isolation: The Rectifier will be disconnected from the AC input
when a preset non-adjustable value is reached.
AC Fail Alarm: The Rectifier issues an "AC Fail Alarm" when AC input voltage
drops below 164Vac. This alarm clears when AC input voltage recovers above
169Vac.
Output Protection:
a) Overload / Reverse Current: An output fuse is provided on each Rectifier. This
fuse is not customer replaceable. The Rectifier can be plugged into or pulled out
of a shelf while operating, without damage or opening the fuse.
b) Current Limiting: The maximum current delivered by the rectifier can be set via
the Controller from 10% to 121% of its rating at maximum rated output voltage.
Output Current Limit Error: ≤ ±1.5A.
c) High Voltage Shutdown:
1) Internal: If Rectifier output voltage exceeds an adjustable preset value and
it is delivering more than 10% of its rated current, the Rectifier shuts down.
After approximately 6 seconds, the Rectifier automatically restarts. If
Rectifier output voltage again exceeds the high voltage shutdown value
within 5 minutes, the Rectifier shuts down and locks out. Manual restart is
then required. If the Rectifier does not experience a high voltage condition
within the 5-minute time-period, the restart circuit is reset.
