3. Features
A DPSI RV is used as a redundant power supply and current distributor
for receivers and servos in RC-Models. The redundancy is
accomplished by using two connected batteries. If one battery fails, the
second battery guaranties safe operation. In the normal case, both
batteries are discharged simultaneously. Furthermore, current is cut in
half in each of “parallel” connected single battery.
All servos directly connected to a DPSI RV are supplied with full power
and each servo obtains maximum current without burden the
damageable receiver.
Due to switching the supply voltage electronically (the switch
transmitter does not switch on the current but only supplies a switch-on
signal), there is no power loss, weak contacts or transition resistance.
For all DPSI RV systems, the electronically switches are built
separately, i.e. the electronically parts are doubled. The switches are
failsafe and are driven by self-holding circuitry, rather by a micro-
controller. Thus, an operating DPSI RV stays powered on, even if the
on/off switch transmitter is removed or broken or if the microcontroller
is malfunctioning.
Using DPSI RV systems, RC receiver sets reach new dimensions. In
particular, a stabilized output voltage, which supplies the receiver as
well as all servos, accounts for. A DPSI RV therefore offers:
Battery switching function
Complete voltage regulation for all RC components
Electronically, failsafe switches
Current distribution with HF filtering
Battery voltage monitoring with acoustically warnings
