5. POWER SUPPLY
Enhanced SmartDrive40 supports input voltage ranges from 10V to 45V. The recommended
power sources are:
●
6 – 18 cells NiMH or NiCd battery.
●
3 – 6 cells LiPo or Li-Ion battery.
●
10V – 45V sealed lead acid battery.
●
10V – 45V power supply (
Must be in parallel with a battery with same voltage
).
The power source can be connected to Enhanced SmartDrive40 either via the terminal block,
or soldered directly to the pad at the bottom layer.
There is no polarity protection on
MDS40B, please double check the connection before connecting to power source.
NOTE:
1.
If a power supply that cannot sink current is being used (example: 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 Enhanced SmartDrive40 will be destroyed
permanently or the power supply trigger protection mode.
