-UP
If the voltage rises to above 12 volts, then the peak voltage state is entered.
Then, when the current has diminished to one-tenth of the maximum
selected current, the float state is entered. If the battery is charged to over
13 volts, turning on the power supply will cause the charger to remain in the
float state.
This turn on cycle occurs following a power outage.
Discharging Battery….
If a load is placed on the battery, and the charger
had been in the float state, and the battery voltage stays above 13 volts, the
charger will remain in the float state supplying up to full current. If the battery
voltage is discharged to less than 12 volts, and the load is removed, the
charger will enter the peak voltage and eventually the float state as above.
If the radio station is connected directly to the battery and not through the
Super PWRgate output, then the battery will supply the load while the battery
is being charged. In fact, the current will be shared between the load and the
battery. This method of powering a radio station was described by W1ZR in
an article in QST, Dec 2003.
LED Indicators
Green (ON)….
Indicates that the charger is fully active and will provide up
to maximum current to the battery according to the battery’s state. Note that
this LED does not measure nor indicate current flow, only the charger’s state,
ie. “fully active state and would charge a battery if it were connected.“
Green (ON) and RED (PK)….
Indicates that the charger is in the peak
voltage state (PK) and will provide up to maximum current to the battery. As
the current is diminishing the charger attempts to reach an elevated battery
voltage. When the current drops to one-tenth the maximum current setting
the state changes to float.
Green (ON) and Yellow (FL)….
Indicates that the charger is in the float state
(FL) and will provide up to maximum current to the battery to maintain the
battery at the float voltage of 13.5 volts.
Choosing and Setting the Maximum Charge Current
The charger has two 40A fuses that are used as a high current switch (need
a high current jumper wire. Note that leaving the fuses out provides a charge
current of 1 ampere. To get different charging current values install the fuses
as follows.
1 Ampere…..
......No fuse
4 Amperes……..
Fuse in left socket
7 Amperes……..
Fuse in right socket
10 Amperes……..
Fuse in both sockets
