Pickup 15.0–30 Vdc
AC Range
24 Vdc:
Pickup 12.8–30 Vdc
Note:
Optoisolated inputs draw approximately 4 mA of current. All
current ratings are at nominal input voltages.
Frequency and Rotation
System Frequency:
50 or 60 Hz
Phase Rotation:
ABC or ACB
Frequency Tracking
Range:
40.1–65 Hz
Note: Voltage connected to V1 required for frequency tracking.
Communications Ports
EIA-232:
2 Side
EIA-485 (optional):
1 Side, 2100 Vdc of isolation
Baud Rate:
300–38400 baud
Time-Code Input
Recloser control accepts demodulated IRIG-B time-code input at Port
1 (optional) and Port 2. Do not connect the time-code input into both
Port 1 and Port 2 at the same time. Recloser control time is
synchronized to within
±
5 ms of time-source input.
Operating Temperature
Relay Module:
–40° to +85°C (–40° to +185°F)
Batteries:
–40° to +60°C (–40° to +140°F)
Entire SEL-351R Falcon
Unit:
–40° to +50°C (–40° to +122°F)
Note: LCD contrast impaired for temperatures below – 20°C (–4
°
F).
The entire SEL-351R Falcon unit was operation tested up to +70°C
(+158°F). The 20°C (36°F) difference between the +50°C rating and
+70°C allows for temperature rise due to sunlight.
