BIC
(Dual Power
Servo interface-Battery Information Center)
DPSI BIC product
description. PDF
The DPSI BIC is the first power
supply concept which, besides a battery switching function and a
“low drop out” voltage regulation, also contains a LC-display, which
provides the user with information about the state of his equipment.
The DPSI BIC displays all important measured values in plain text.
Besides the battery voltages and the current flow of the connected
loads the withdrawn capacity and on-time are displayed. Rough
running push-rods or defective servos can be diagnosed by increased
current consumption. Reduced battery capacity or defectiveness of
the batteries are also detected in time. An acoustically error
indication makes sure, that the user does not miss any malfunction.
Different battery types can be programmed to ensure correct voltage
monitoring. The intelligent algorithm evaluates discharged batteries
reliably.
Three printed
circuit boards, equipped on both sides with most modern
parts allow for optimal space usage and are integrated into
a stable and ergonomic housing. Usage of pin-and-socket
connectors allow for simple exchange of connector cables and
guarantees maximum flexibility. The generous sized heat sink
serves for good heat dissipation and allows for high
currents of the connected loads. Therefore, receiver sets
with up to 8 digital servos can be supplied from the DPSI
BIC without problems. If using 5-cell NiCd/NiMH batteries
even up to 15 servos can be operated.
|
An optional external switch allows for applications where no direct access
to the pushbuttons of the DPSI BIC is possible. The DPSI BIC
can therefore be used as a cockpit instrument while the
switch is mounted into the side wall of the fuselage. The
ultra bright LED in the switch indicates operation and
errors optically.
|
There is additional accessory available, which contains all parts to
provide existing batteries with MPX sockets and to connect
the receiver (via a doubled high grade connector cable). An
additional bracket for spare completes the set.
The DPSI BIC is packet in a stable plastic case and
delivered with a detailed operating manual (the guide also
is available for download found in DOWNLOADS).
|
The DPSI BIC is available in 4 colors - as well as the
optional external switch (red, blue, black, white).

DPS
(Digital Power Switch)
DPS product
description. PDF
The high power switches present an alternative to the
traditional on/off switches. The switching operation is
carried out totally electronically using power
semiconductors. A pin turns on an integrated electronically
switch with lock when put into the "On" female connector.
Only changing the pin to the "Off" female connector turns
the DPS off. An ultra bright LED signals the active system.
Batteries up to 8.4 volts can be connected. The maximum
continuous current is approx.
8 amps (temporarily 20 amps).
|
Two versions (connection cable with JR UNI contacts or with MPX high
current connectors) allow for the usage in regular receiver
applications as well as for e.g. ignition equipment. An
integrated ESD protection guards the parts from high voltage
peaks (e.g. through static discharge). The Digital Power
Switch can also be used for products of other manufacturers
which do not yet own a fail-proof electronically switch
(e.g. for battery switching).

DPSI RV - Regulated Voltage
In layman's terms, power
your servos from a dual power source without loosing power
by sending the voltage through the receiver. These products
are HIGHLY recommended for large sailplanes like our Nimbus
4 and ASW 28, as well as large TOC type airplanes. |
|
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 6.0 volts. 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)
is/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. This 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. 1200 milli amps/h at
2.1 oz(60g) weight, 1500 milli amps/h at 3 oz (85grams),
2000 milli amps/h at 4.3 oz (122grams) and 3300 milli amps/h
at 5.8 oz (167 grams). These batteries can withstand
currents of up to 20 amps. With parallel connection of two
battery packs by means of the DPSI-RV, peak currents of up
to 40 amps are possible without any problems, without the
voltage breaking down.

DPSI RV LDO
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 servos.
Thus there are always up to 4 servo connections available for all
important functions. |
|
 |
DPSI RV Mini 5
The DPSI RV Mini 5 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 per rudder flap 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. |
|
 |
DPSI RV
Mini 6
The DPSI RV Mini 6, for example, is
of interest for models with 4 surface servos (jets, gliders). Here 4
channels for the rudder flaps are used in the wings (aileron left,
landing flap left, landing flap right, aileron right). The two
remaining channels are provided for the vertical rudder (1 servo)
and the elevator (2 servos, e.g. one each per rudder). The turbine
ECU (or tow release, landing gear, etc.) is then plugged directly to
the receiver, for example. |

DPSI TWIN
Double receiver = double
safety! |
|
In addition to the redundant power supply, the DPSI TWIN now also ensures
redundancy of the complete receiver. The TWIN version is
based on the DPSI RV LDO and enables the use of 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. In addition to the failsafe function with
automatic switching between two receivers (at the same
frequency), it is also possible to use two receivers with
different frequencies. Thus two completely separate (or
different) transmitters can be used (and even two completely
different receivers as well), which opens up unheard of
possibilities. |
|
To obtain information about the status of the entire system,
the DPSI ICE (Information Center) can be attached to the
DPSI TWIN, as an option. All of the relevant information is
displayed in this cockpit instrument (1.6" (40mm) diameter)
by means of 8 LEDs (which receiver is currently active, how
many interferences have occurred, are the batteries dying,
etc.). It is then easy to tell after each flight whether any
interferences occurred. This information can be used to
promptly determine defective receivers and/or crystals, for
example. In the case of a faulty range test, new positioning
of the receiver or antennae - among other things - can be
used to improve reception. It is thus possible to achieve
qualitative improvements of the entire receiver system. |
|
It is also possible to communicate with a PC using the
optional K/RS232 interface. The K-interface stems from the
automobile industry and represents a simple bidirectional
one-wire-interface. Thus a normal DPSI servo cable suffices
as a connection between the DPSI TWIN and the K/RS323
interface for exchanging data with the PC. Using the PC
software, it is possible to program the parameters of the
DPSI TWIN (output voltage, stick positions, type of battery,
etc.) All relevant operational parameters of the last flight
are recorded by the data logger
function of the DPSI TWIN and saved in non-volatile
memory. Thus, if a model crashes, the cause of the crash can
be determined without a doubt (due to interference in both
receivers, for example, or to low voltage). Analysis of the
causes of a potential crash is especially important for
expensive models in order to rule out technical failure
where applicable.
