The Kpower DM1500 is a digital servo for 1:8, 1:10 and 1:12 RC cars, with additional applications in pool-cleaning robots, smart toilets and smart switches. Its 4.8–7.4 V operating range, copper gears and 210° ± 1° travel support controlled mechanical movement. Voltage-specific speed, torque and current specifications help match the servo to the power supply and load requirements of a project.
Features
Digital servo with copper metal gears and a plastic case.
210° ± 1° travel angle with a 900–2100 μs control-signal range.
50–333 Hz refresh frequency and 6 μs dead band.
Waterproof construction; no IP rating or immersion limits are specified.
22 AWG PVC wiring.
