Product User’s Manual –
5.0 POWER SUPPLY
supports input voltage ranges from 7V to 25V. The recommended power
sources are:
●
6 – 18 cells NiMH or NiCd battery.
●
2 – 6 cells LiPo or LiIon battery.
●
7V – 24V sealed lead acid battery.
●
7V – 24V power supply (
Must be in parallel with a battery with same voltage
).
The power source can be connected to SmartDrive40 either via the DeanT connector, or
soldered directly to the pad at the bottom layer.
NOTE:
1.
If a power supply that cannot sink current is being used (bench top and AC to DC
switching power supply), the input voltage will rise when the driver is regenerating
(motor is slowing down). Thus, it is important to connect a battery with same voltage
in parallel with the power supply to absorb the current generated by the motor. Else,
the input voltage might rise to a level where SmartDrive40 will be destroyed
permanently.
2.
For application where the current is > 20A, it’s recommended to solder the wire
directly to the pad at bottom layer.
Steps to solder the wire to the DeanT connector are shown below:
The items needed to solder wire to

1.
Before start soldering, identify the polarity of DeanT connector. There are + and –
marking on the DeanT connector.
