POWER DIV.EMCOTEC DPSI RV LDO ADSMINI

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 theDPSI

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.
