Radient Duplex Duplex RDNA0397 Owner's manual - page 8
Safe
The Duplex charger uses advanced charging calculations which allows the safe
charging of all batteries and minimizes the risk of user errors.
Versatile
The Duplex will charge and discharge a wide variety of battery chemistries such as
LiPo, LiIon, LiFe, NiMH, NiCd and Pb.
Simple
The simple and efficient user interface makes operation easy. The displays shows in
real time the Duplex’s powerful functions allowing you to monitor the battery/voltage
charge, current/temperature of batteries, together with the charge capacity or the
elapsed discharge time or input voltage etc. Therefore, you can accurately establish
the present state and conveniently establish safe charge or discharge parameters.
Balancing individual cells
During the charge or discharge process, the Duplex can monitor and individually
balance each of the battery’s cells. During the process, it can monitor and
individually balance each cell in the pack within a tolerance of 0.01V.
Fast lithium battery charging and storage mode
Lithium battery charging requirements vary. ‘Fast’ charging reduces the duration of the
charge period, whereas charging to a ‘store’ state can control the final voltage of your
battery, so that batteries can be stored for an extended period of time and protect the
useful time of the battery. The Duplex is also capable of cycle charging/discharging to
condition batteries.
Convenient data storage
For user convenience, the Duplex can store and load charge/discharge date for a
maximum of twenty different batteries. You can store the data containing the desired
charge or discharge settings of a battery to recall at any time.
Maximum Safety
Delta-peak sensitivity: The automatic charge termination method is based on the
principle of Delta-peak voltage detection. When the battery’s voltage exceeds the
threshold, the charge process will be terminated automatically.
Automatic limit of charging current
You can set the charging current upper limit when charging your NiCd or NiMH
battery. This is particularly useful when charging NiMH batteries with low
impedance and capacity using the ‘AUTO’ charging mode.
Capacity limit
The charging capacity is always calculated as the charging current multiplied by
time. If the charging capacity exceeds the limit, the process will be terminated
automatically when you set the maximum value.
Temperature threshold*
During charging, the battery’s temperature will rise. If the temperature limit is
reached, the charge process will be terminated.
*This function is available by connecting an optional temperature probe, which is not
included with the Ascert charger.
Input power monitoring
If using a car battery as the power source, its voltage is monitored to protect it from
damage. The voltage drops below the lower limit, the charge process will be
terminated automatically.

SPECIAL FEATURES
4>Set up DC power supply voltage and current
5>Brushed motor drive
The voltage of each cell is shown in this display.
The charger's output can be used as a DC power supply.
Press the ‘Start/Enter’ button. Press the ‘Decrease’ or
‘Increase’ button to adjust the digital power’s voltage. Press
the Start/Enter button again to adjust the current. The voltage
range is 5.0-25.0V and the current range is 0.1-10.0A.
Press the ‘Start/Enter’ button for more than 3 seconds. The
display will show the current, voltage and digital power
duration and Wattage. Note that the maximum power is 50W
per side.
The brushed motor must be connected to the appropriate
charger outputs.
Press the ‘Start/Enter’ button twice to select the test
duration (in minutes). Use the ‘Decrease’ and ‘Increase’
buttons to adjust the value. Now press the ‘Start/Enter’
button select the current, followed by the Voltage and
adjust the values in the same way.
Now press the ‘Start/Enter’ for more than 3 seconds to
start the new process. A beep will sound as the process
begins. The test time range is 1-90 min, Current is 0.1-20A,
and the test voltage is 1-15V
You can easily break-in a new bushed electric motor using a variable voltage and
running time. With this function you also check the motor’s performance to optimize
your power-train.The break-in process is essential for maximizing the power of a new
brushed motor. New motors have square brushes which press up against the curved
commutator.The break-in process gently shapes the brushes so that they develop a
curved surface that fits snugly against the commutator giving greater conducting
surface area with lower losses and higher effciency.
