SSPS-105 Super Hi-Power servo for RC models

This is our flagship model - this hi-power servo has been developed by Tonegawa-Seiko co. since 1975. The 105 Series is a line-up of models that have been met a lot of applications. The bodies are made of die-cast aluminum. Since these models have superior water resistance design, they can also be used under critical conditions. Used in R/C planes having wingspans of over three meters or in 1/4-scale radio-controlled model cars.

    • Wiring diagram (when using R/C receiver)

Five wires come out from 105 servo.

Three of these five wires, are used for control signal with photo cuppler drive. Connectors are provided that enable direct connection to FUTABA or JR receivers, so the unit can be used immediately.

In addition, you have to prepare a separate power supply for the servo power motor drive power. Note that we have 12V or 24V operating voltage model selection. Be sure to select the one that meets your system power unit for this.

    • Sample wiring diagram without RC radio system.

The wired control unit is available by our product, instead of a RC radio.

Servo motor control can be accomplished by voltage to pluse width conversion with CPU A/D converter unit.

The control voltage is by a 5kB VR/POT or D/A etc. 5V regulator is mounted on the board, so the operation can be within a range from 6V to 12V.

Precautions

This product was developed for radio-controlled applications. Always observe the following points when using in industrial equipment and other applications.

  1. This product is extremely powerful. Always have the required safety measures in place before operating.
  2. Always check that the linkage and other such components operate properly.
  3. Avoid operating methods that will subject the unit to continuous high loads. (Such as holding heaving objects.) Please refer to Operating Manual.
  4. Never use in life-support equipment or rescue-related products.
