PSU Current Measurements
Pressing ‘
enter’
accesses the two current measurement menus by scrolling up and down using the arrows.
Output Currents
After pressing
enter,
the display will briefly
show this message, whilst connecting….
Followed by a typical display like this:
The bottom
‘Outputs’
display shows the total current being used by outputs 1 and 2. This does not include the
battery charging current. You can quit the Output Currents display by pressing the up arrow key.
NOTE:
There is a
300mA reserve of battery current, for example if a 5A PSU is already providing 5A, an extra
300mA (depending on the battery charge condition) can also be provided. In this case a total of 5.3A is being
supplied.
Battery Charging Current
Selected by pressing ‘
enter’
, the following display is shown:
The current shown is typical of a fully charged battery.
NOTE:
If the battery current is varying wildly, this will probably be due to a discharged battery taking significant
charging current and sharing the total current capacity with the output load, where the load is varying.
PSU Voltage Measurements
Three different menus are available in this measurement mode, these can accessed by pressing ‘
enter’
and
using the scroll arrows.
Battery Voltages
When selected, the following display is
shown:
The battery voltages shown is typical of a fully charged set of batteries. Battery 1 and Battery 2 voltages are
shown separately, the bottom Batteries voltage display is the sum of the individual battery voltages.
NOTE:
The individual battery voltages will seldom be identical, but should be balanced to at least 1V with
respect to each other. Actual voltage values will depend on the charge state and temperature and are not
necessarily related to the PSU charging voltage.
Output Voltages
When selected, this display is shown:
The output voltages will vary according to temperature and load current and will not necessarily be identical.
NOTE:
Voltage at the load will vary according to current causing voltage drop by the installation wiring. There
will also be a small difference (a few tens of millivolts) caused by the PSUs small internal resistance needed for
current monitoring. This is will be reflected by a small variations of the displayed voltage readings shown on the
screens and is normal.
Charging Voltage
When selected, this display is shown:
The charging voltage is the internal PSU voltage used for battery charging when AC power is present and is
dependent on temperature.
NOTE:
The charging voltage, battery voltage and output voltages will not necessarily be the same depending
on mode and conditions.
Waiting for Data
Output 1 = 1.20A
Output 1 = 0.30A
Outputs = 1.50A
Battery Charging
Current
0.02A
Battery 1 = 13.34V
Battery 1 = 13.65V
Batteries = 26.99V
Output 1 = 27.01V
Output 2 = 27.03V
Voltage at load will
drop with current
Charging = 27.00V
