The voltage for the receiver AND the servos is regulated at a constant value for the first time in this new range of products. The problems that arise with traditional, fully loaded, 5-cell batteries are therefore eliminated. The entire receiver station is now supplied with stable voltage, which the user can adjust via jumper to a range of 4.8 to 6.0V. Thus allowance is made for every type of application.
For the first time, a micro-controller is integrated into the DPSI RV, which monitors the battery voltages by means of an intelligent algorithm. When the battery (or batteries) are 60-70% discharged, this status is acoustically announced by a built-in buzzer. This rules out the risk of empty batteries. There is always enough reserve to complete a flight and then charge the batteries.
The generous dimensions of the cooling surfaces and the voltage control now make it possible to use new battery technology such as lithium-ion or lithium-polymer cells. These extremely light cells have an energy density up to 400% greater than NiCd cells, for example. Which means, high capacity with low weight. The LONGGO batteries are the premium product among the lithium-polymer power sources. Two selected and matched lithium-polymer cells are each assembled on a high performance receiver battery, which is available in four different capacities. 1200mAh at 60g weight, 1500mAh at 85g, 2100mAh at 122g and 3300mAh at 167 grams. These batteries can withstand currents of up to 20A. With parallel connection of two battery packs by means of the DPSI-RV, peak currents of up to 40A are possible without any problems, without the voltage breaking down.
The DPSI RV Twin version is based on the DPSI RV LDO and enables complete redundancy by using two receivers, which can be automatically switched between, at your option (depending on signal quality). This means that for the first time the entire receiver station is doubly secured. A failsafe signal of the receiver is used to switch over to the second receiver in case of a failure. Thus a total of 8 channels are completely switched over and distributed to 25 servo outputs. For the first time, ALL servos can continue to be controlled in the event of a receiver failure. The system is also suitable as a teacher-student system or as a "pilot backup". A second pilot (or "student") can take over the entire model along with all control functions using his own transmitter by means of deliberate switching (or due to an interference).
The DPSI RV is suitable for all large models (motorized models, jets, airliners, large gliders, etc.) 12 receiver channels can be distributed to a total of 32 steering gears in this case. There are always up to 4 servo connections available for all important functions.
The DPSI RV Mini is suitable for medium-sized motorized models (approx. 2.20 m - 2.70 m wingspan). Here, as a rule, 2 servos are used for each aileron, for the elevator 1 servo each, and 2 servos for the vertical rudder, if required. Additional servos (gas, choke, tow release or the like) are then attached directly to the receiver. In this way, all servos that use a lot of power and have long connection cables are supplied directly by means of the DPSI.
