DPSI RV Family Operating Instructions Version 2.1

If for center of gravity purposes, the batteries are to be placed far away
from the DPSI (i.e. long connection cables), it is advisable to twist the
cables of the batteries.
We recommend using our EMC Lithium Polymer batteries. These are
supplied completely cabled and can be attached immediately to the
DPSI. An additional charging connector at the battery enables charging
without having to disconnect the battery from the DPSI. Charging
devices for all battery types are also available from EMCOTEC.
Selecting the output voltage
Meanwhile, almost all servos and receiver are applicable for a supply
of 5.9V. Therefore, the default setting for directly to a DPSI connected
servos is 5.9V (DPSI 2001 RV) or 6,0V (DPSI RV). If 7.4V servos are
to be used, the output voltage of the DPSI can be set to 7.4V by
jumper. In case of using a LiPo battery the servos are supplied 7.4V.
Hint:
The higher the difference between the input- and output voltage, the higher the
power dissipation converted to heat. If using many servos, it is advisable to select
a higher output voltage at the DPSI.
Recommendation for output voltages of DPSI RV:
