Input Protection:
a)
Fusing: The rectifier contains double pole/neutral fusing (non user-replaceable). Customer is to
provide AC input branch circuit protection.
b)
Low Input Voltage: The rectifier shuts down and its protection indicator (yellow) illuminates if input
voltage decreases below 85VAC. The rectifier automatically restarts when the input voltage returns
to within the normal operating range. A low input voltage condition does not trip the recommended
input protection device.
c)
High Input Voltage: The rectifier shuts down and its protection indicator (yellow) illuminates if input
voltage increases above 280VAC. The rectifier automatically restarts when the input voltage
returns to within the normal operating range.
d)
Power Interruption: Interruption and restoration of input power does not affect the proper operation
of the controls, alarm signals, or visual indicators. On restoration of input power, the rectifier
automatically restarts without manual intervention and without operating protective devices, even if
connected to a completely discharged battery string or capacitor bank.
•
Output Protection:
a)
Current Limiting: The maximum current delivered by the rectifier can be programmed from 10% to
120% of full load rating via the controller. If communication to the controller is lost, the rectifier
default value is 121% of full load rating. Full load rating for rectifier is defined as the maximum
current available over the entire output voltage range (88A for R24-2500, 104A for R24-3000). The
rectifier can start when connected to a completely discharged battery or capacitor bank without
operating rectifier protective devices or needing any manual intervention.
b)
Fusing: The rectifier contains an output fuse (non user-replaceable). Rectifier output power is lost
and its fault indicator (red) illuminates if the output fuse opens The rectifier can be plugged into or
pulled out of a shelf while operating, without damage or opening the fuse.
c)
High Voltage Shutdown:
1.
Adjustable Control: If rectifier output voltage exceeds an adjustable preset value and the
rectifier is delivering more than 10% of its rated current, the rectifier shuts down. (Adjustable
from 24.00 VDC to 29.75 VDC via the controller. The restart hysteresis is 0.5 V ±0.2 V.)
The rectifier then restarts and a HVSD restart timer starts (time value configurable via the
controller, factory default is 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 or by removing the rectifier,
waiting until the LEDs on the rectifier extinguish, then turning power to the rectifier on or re-
inserting the rectifier). 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.
2.
Backup: If rectifier output voltage exceeds 31.0 V ±0.5 V (non-adjustable) and the rectifier is
delivering more than 10% of its rated current, the rectifier shuts down. The rectifier then
restarts and a HVSD restart timer starts (time value configurable via the controller, factory
default is 5 minutes). If output voltage again exceeds the high voltage shutdown value before
