ECO Charger EC-90 Owner's Manual - page 4
CHARGER
The EC-90 has a built in dual rate charger with temperature compensation. The circuit is
activated by connecting the Eco-Charge PS-151 power supply to the “CHARGER IN” XLR
connector on the battery. Charge status is monitored by a LED indicator located next to the
“CHARGER IN” connector.
REGULATED OUTPUT
The dual voltage EC-90 uses a high efficiency switch mode regulator to provide 6V or 7.5V
output from the 12 volt battery. This regulator has a maximum output current of 2 Amperes.
The switch mode regulator is activated when the proper power cable is connected to the
XLR output. To avoid draining the battery, it is advised to remove this power cable when
not in use.
SHORT CIRCUIT PROTECTION
The EC-90 is protected from short circuit by an automatic resettable fuse. The fuse is
designed to interrupt the flow of dangerously high current during fault conditions. It will
automatically reset after the fault is cleared and power to the circuit is removed.
OPERATION
CHARGING
Fully engage and lock the male XLR connector on the PS-151/PSE-151 power supply
to the “CHARGER IN” female XLR connector on the battery. This connector is located
on the right side of the battery and is surrounded by a red box on the top battery label.
The LED charge status indicator is located to the right of the charger connector. Plug the
power supply into the proper voltage receptacle. The charger circuit should now be on
and charging the battery. The LED charge status indicator is RED during the charge cycle
and will turn OFF when complete. At this point, the battery may be used. Charge times
vary with the amount of use. The first charge will take longer than normal as the battery
chemicals form. Do not interrupt the charge process for optimum battery performance.
WARNING
The EC-90 battery requires a 15V / 1A unregulated power supply to activate the internal
charger circuit. The power supply is available from Eco-Charge. The PS-151 is for 110V
outlets, the PSE-151 is for 220-240 outlets.
Use of any other power supply may damage
the battery. Do not use a sealed lead acid battery charger with the EC-90, severe
damage may occur.
