Battery Current & Voltage Bar Graph Meters (
GREEN, YELLOW, RED
).
d. Current Indicator.
This illuminated Bar Graph monitors the current
being drawn from the battery by the inverter. Depending on the amount of
current being drawn, the Bar Graph reading generally will be in the GREEN
or YELLOW zone. When the reading rises to the RED zone, the inverter
may automatically shut down. In this event it is likely that the draw of the
equipment or appliance being operated is greater than the battery is
capable of producing.
Voltage Indicator.
This Bar Graph indicates the DC voltage available at
the input terminals of the inverter. This voltage will be lower than the voltage
at the battery terminals by an amount equal to the voltage drop along the
input cables and connectors. This drop is equal to the product of the input
current and the resistance of the cables and the connectors. When the
output power is low, the input current will be low and the drop will also be
low. The input voltage at the inverter will thus be almost equal to the battery
voltage. At higher output loads, the input current will be higher and the drop
will also be higher, in this case, the input voltage at the inverter will be lower
than the battery voltage.
The inverter is designed to operate with input voltages ranging from 10 to 15
volts of direct current (DC). When the voltage drops below 10.5 volts DC,
the voltage indicator will register in the lower RED zone and an audible
alarm will sound. If the voltage drops below 10 volts DC, the voltage
indicator will go out and the inverter will automatically shut down.
The inverter will also shut down automatically when the input voltage
exceeds 15 volts DC.
Despite this “built in” protection the inverter may be damaged if the input
voltage exceeds 15 volts DC and damage caused by excess voltage input is
not covered under the warranty. Under optimum conditions, the voltage
reading will be in the GREEN zone.
Note:
In the event of automatic shut down or continuous audible alarm, turn the
inverter OFF (O) until the source of the related problem has been deter-
mined and resolved.
e.
Two Standard North American NEMA 5-15R Receptacles
are
provided on models PSE-12100A and PSE-12150A. On PSE-12250A, the
output is available from unconnected, Live (BLACK), Neutral (WHITE) and
Earth ground (GREEN) wires for connection to an external breaker panel. A
plate with standard North American NEMA 5-15 receptacles(e) wired in
series with a 15 A circuit breaker (j) is provided as an accessory. Use this
receptacle if you require power to be drawn from the front panel. (This will
require connection). As this receptacle(e) is fed through a 15A breaker (j),
the power drawn from here should be limited to 1500 watts.
