Features
High/Low Voltage Protection | The EMS continuously monitors AC power.
When AC power deviates below 104 volts or above 132 volts, the EMS
automatically shuts down power to the RV. Once the AC power rises above 104
volts or drops below 132 volts, the 2 minute 16 second (136 seconds) time delay
counts down and power is restored automatically.
Time Delay for A/C Compressor | When first plugging in, if AC power is
interrupted, or the EMS detects a fault, the 2 minute 16 second time delay is
activated.
3-Mode Surge Protection (EMS-PT30C) | This feature provides full surge
protection L-N, L-G, and N-G. Rated: 1,790J, 44,000A surge current. Response
time <1 Nano seconds.
5-Mode Surge Protection (EMS-PT50C) | This feature provides full surge
protection L-N, L-N, L-G, L-L, and N-G. Rated: 3,580J, 88,000A surge current.
Response time <1 Nano seconds.
Surge Indicator | The EMS will indicate E10 if the surge protector is damaged in
the EMS, L-N, or L-G, due to a power surge.
Reverse Polarity Protection | If AC power has a reverse polarity condition, the
EMS will indicate E-1, and not allow power to the RV.
Open Neutral Protection | If AC power has an open neutral, the display will not
light, and the EMS will not allow power to the RV.
Open Ground Protection | If AC power has an open ground condition, the EMS
will indicate E 2, and will not allow power to the RV.
AC Frequency Protection | If AC power frequency deviates plus/minus 9Hz
from 60Hz, the EMS will indicate E 7 (low frequency) or E 8 (high frequency)
and will not allow power to the RV.
Accidental 240V Protection | If 240 volts is detected, the EMS will indicate E 3
and 240V, and will not allow power to the RV.
Display | Display continuously scrolls at (2) second intervals all AC power
information: voltage(s), current(s), frequency, error code, previous error code (if
applicable).
Previous Error Code | Previous error code (PE) indicates what error occurred
and why power was interrupted. To delete code, disconnect power from EMS.
Weather Resistant | Can be exposed to elements, however, may not be
submerged. Unit is designed to be mounted or used vertically.
Microprocessor Controlled | The EMS utilizes a state-of-the-art microprocessor
with proprietary software.
Built-in Lock Bracket | Allows owner to prevent theft by securing the EMS to
power source pedestal using a lock, such as a bicycle cable lock.
