• Input Protection:
a) Fuse: On the input, two UL recognized fuses are used, not user-replaceable.
b) Input Voltage Protection: Derating from 85 VAC to 176 VAC (R48-3200, R48-3200e, R48-3500e) or
85 VAC to 185 VAC (R48-4000e). Withstand 415 VAC input without damage.
1. The rectifier will shut down at low or high voltage input; low voltage disable point: 80 V ±3 V;
Hysteresis at least 15 VAC for restart. High voltage disable point: 295 V ±5 V for R48-3200 and
R48-3200e, 310 V ±5 V for R48-3500e and R48-4000e; Hysteresis at least 10 VAC for restart.
2. Between 85 VAC to 176 VAC (R48-3200, R48-3200e, R48-3500e) or 85 VAC to 185 VAC
(R48-4000e) the output power will be derated linearly according to input voltage per Figure 5,
Figure 6, Figure 7, and Figure 8.
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 164 VAC. This
alarm clears when AC input voltage recovers above 169 VAC. This level can be set by the controller.
• 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: ≤ ±1.5 A.
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 56 VDC to 59 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 59.5 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
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).
