AmpFlow high-efficiency power supplies have an output voltage that is adjustable by plus or minus 10%. And they include an EMI filter to minimize interference with radio signals and a soft-start circuit that reduces the AC inrush current peaks.
Built-in current limiting protects the unit from overloads and short circuits. The current limiting feature enables these power supplies to keep functioning through the high-current start-up surges from DC motors. Most power supplies designed for use with LED lighting or other electronics will simply shut down when exposed to the high current demands of DC motors. AmpFlow power supplies are designed specifically for use with electric motors. Our power supplies will just limit the current to the rated maximum, even when a larger load is called for (like when a DC motor starts up). Also, inductive loads (like DC motors) can cause damage to power supplies that are not designed for them.
If the motor is likely to keep spinning after the power has been turned off, the reverse voltage generated by the motor can cause damage to the power supply. The use of a diode will prevent this reverse voltage from reaching the power supply. Here are sketches for diode placement for Brushed and Brushless motors. In most cases, these diodes are not required, but they are recommended for applications with high inertia.
