The Power Box 40 was developed by Modellbau Deutsch provide you with a reliable twin-pack power supply for the receiver in your model aircraft.

The extraordinarily high performance of the electronic modules (2 x 20 A) and the suitably dimensioned circuit board providing two independent voltage controllers for each battery pack, the external LEDs which can be optionally plugged in for each pack, all these features are components not used in model construction until now in connection with the cross-over function.

The sockets for the battery-pack inputs are firmly integrated into the circuit board as so-called high-current sockets designed for high currents and low transition resistance and, for safety purposes, provided with triple-plug contacts for each battery-pack pole.

The two cables connecting the receiver are designed with double cable cross-section, supplying power to both receiver and servos via two gold plug connectors so that, if our cross-over is used, these contacts are also double. These supply cables are, naturally, pull-relief installed in the Power Box, and the solder points on the circuit board are protected in a vibration-proof way by means of special adhesive.

The high performance of the electronic components enables the current to pass from the battery packs to the receiver without high current losses, so we have no hesitation in recommending operation with even four cells (important in the case of JR/Graupner remote-control components). You can connect your battery packs straight onto the Power Box 40 via a high-current plug. It is, however, more convenient to use external switches to connect the supply of current. For this purpose we have developed switches that cannot be compared to those with which you may have been familiar until now. Our Power Switches have an output of 20 A, simultaneously switching four floating double contacts. All connection cables are securely soldered to generously dimensioned surfaces, all connection cables, including the circuit board, are glued in the housing with special adhesive so as to be relieved of strain and resistant to vibration. A green LED indicates the switching position, a charging socket for charging currents up to 2 A is provided.

Should you have any questions regarding the power supply for your model, we would be pleased to advise you.
