Selecting the output voltage
Meanwhile almost all servos are suitable for a 5.9V supply voltage.
Therefore, the default setting for servos directly connected to the DPSI
RV Mini is 5.9V. If 7.4V servos are to be used, the output voltage can
be set to battery level ("Bat.") by jumper. In case LiPo batteries are
used servos are supplied with 7.4V.
Some servos are restricted to 4.8V according to manufacturer's
specifications (e.g. fast tail rotor servos for helicopters). Connect these
servos directly to the receiver. Its supply voltage then is set to 5.2V by
jumper at the DPSI RV Mini. 5.2V correspond to the voltage of 4-cell
NiCd batteries which are the reference for 4.8V servos.
As of today, all commercially available receivers can be operated with
5.9V with no limitation. Therefore, the receiver voltage at the DPSI RV
Mini is set to 5.9V by default.
Hint:
The higher the difference between input and output voltage, the higher is the
power dissipation which must be converted to heat. If using many servos it is
advisable to select a higher output voltage at the DPSI RV Mini.
Hint:
Using a 4-cell battery pack (NiCd/NiMH) on a DPSI RV Mini is not permissible!
