MODEL
# ES350 240VAC 50 AMPS/POLE
Automatic
Transfer Switch
Automatic switching between shorepower, generator and inverter
- Designed
for rigorous use utilizing two heavy duty contactors rated up to 50 amps
- 120/240v
shoreline, 12kw generator and an inverter relay rated 6kw, 50
amps 120v
- Transfers
both hot and neutral legs simultaneously
- Designed
to shed inverter power loads when used with a 30 amp transfer switch
- Utilizes
both mechanical and electrical interlocks to insure no power feedback
- Capable
of monitoring voltages on both the generator and shore line - specify
volt board when ordering
- Built-in
time delay allows generator to get up to speed
- Quick
and easy installation
- Designed
for OEM and aftermarket applications
The
ES350 is designed to monitor both legs of the generator supply with the
generator always being the dominant source. In addition to functioning
as a generator time delay (average 30 sec.), the integrated control
circuitry monitors the generator supply voltage. Should generator power
output drop to 105VAC or less for 5 seconds after the time delay
sequence, the control board switches power back to the shore input. If
shore power is not available, the ES350 will source inverter power.
Once the generator output measures above 105VAC, the ES350 will switch
from shore power or inverter power back to generator power.
The
ES350 is designed for use with generators having a rated output of 50
Amps at 120/240VAC single phase 60 Hz, an external power source (shore
cord) of 50 Amps at 120/240VAC single phase 60 Hz and an AC inverter
supplying up to 50 Amps at 120VAC.
