AC Automatic Master
Control
Shore power is the dominant input
(master). Five seconds after shore power is energized with the genset running the AC
master control will take the genset off line and after a three second delay automatically
engage the shore power.

A/B Selector
|
|
The A/B Selector is a 2-input, 1-output auto-selector utilizing a "primary/
secondary" selection method for input. When connecting to dockside
power,
the 9R-ABSEL50I-C (240v) and the 9R-ABSEL30/50-C (120v) will
automatically sense the incoming dockside AC source and transfer it to the
output. When adequate AC power appears on the Primary input, the Secondary
input is immediately disconnected and locked-out from operation (even if already
in operation).
Benefits:
- NEMA Type 3 Enclosure
White, non-conductive polycarbonate material, allowing for safe
isolation of AC power.
- Easy to Install
Flange mounted with top-side AC terminals.
- Mechanical A to B Lockout
Mechanically interlocked to inhibit simultaneous operation
- Electrical A to B Lockout
Components are electrically locked-out to inhibit simultaneous
operation.
- 120 Volt or 240 Volt 50 Hz
or 60 Hz Input
The 9R-ABSEL50I-C is for 220 or 240vac. The
9R-ABSEL30/50-C is for 115 or 120vac.
- Up to 50 AMPS Per Input
Each input is rated to accommodate three wires plus ground at 50
AMPS at 120 or 240vac.

with Charles C-Power®
AC Master Control for Totally
Automatic AC Input
Builder's Requirements
Maximize AC input
capabilities and flexibility.
- Automatic selection of first in (fore or aft)
connection with auto lock out of second source.
- Electrically isolate the yacht from the dock.
- Boost 208 dock voltage to 230 volts.
- Supply 220 volts to the panel from 110 volt input.
- Sense AC input sources and direct power to the panel.
- Do all of the above automatically without manual
switchgear.
Charles Solution:
- Install one 93-ABSEL501-A to automatically select the
220V50 amp input and one 93-ABSEL30/50 to automatically select the 110V 30 amp input.
- One 93-ISOBOOST50-A on the 220V input and one
93-IXFMR3/8-A on the 110V input accomplish these requirements.
- A 93-IXFMR3/8I can be wired for 110V 30 amp in and
220V 15 amp out.
- The 93-ACMC50I-A senses AC input and directs the
current to the panel.
