CHOOSING A POWER SUPPLY
There are two important parameters to consider when choosing a power supply in your
application, voltage and current.
Motor Power Supply
Voltage Input Range: 12 to 36 Vdc
Refer to your motor label for rated voltage. The integrated motor control is intended to be
operated from a low voltage DC power supply rated between
12 to 36 Vdc
. The maximum voltage
of the GreenDrive
TM
is 42 Vdc, therefore do not exceed this voltage. The maximum continuous
operating current handled by the GreenDrive
TM
is 10 amps. Where the maximum motor current
is less than 10A, the power supply rating should be based on the rated motor current as shown
on the nameplate. Filter capacitors are supplied internal to the GreenDrive
TM
control for
increased reliability under typical power conditions. It is recommended that the power supply
meet the latest editions of UL60950 and CSA 60950 specifications.
Current Input Range: 3x Rated Motor Current (Typical)
The maximum or rated power supply current needed should typically be at least three times the
rated motor current to ensure adequate current headroom for intermittent motor overloading.
