Gryphon Extreme-Heli DC-DC Voltage Regulator - BLACK

☞ The case that the servo specifications are the same : If operating voltage specifications of four channel servos are all the same, all four channels are connected., ☞ The case that the servo specifications are different : If it is used three CCPM(6.0V) and a throttle servo(4.8V) mixed with devices such as governor, the throttle servo should be used to directly connect with the receiver.,

RX channel 5.2V(Fixed)
RX channel 5A(MAX10A)
Operating guide
Features
◆ As the world's famous products have kept just DC-DC voltage regulator of linear type, this product is also dual channel linear regulator that wouldn't fundamentally generate switching noise and ripples contrary to switching-type regulator and has superior voltage stability, current supplying capability, and transient response against radical load variation. Therefore, it is enable to safely apply to PPM, PCM schemes as well as all system including 2.4GHz.
◆ Total electric current consumption during extreme 3D, F3C flight approaches 8A. Thus traditional power supply scheme has limits not to effectively operate servos. To improve it, this product is applied with the reboost power bus scheme based on new concept that a regulator directly supply power to a servo for each channel instead of passing battery power through a receiver.
◆ Contrary to existing products that two same regulators are packed in a case, it has manufactured that each electronic device can achieve the best performance with designing hybrid type to use each other output component for CCPM servo's circuits emphasizing the power and responsibility, RX and Gyro's circuits emphasizing the voltage stability and noise-free.
◆ Output voltage setup is designed to choose required voltage among five preset voltages of 5.2V, 6.0V, 6.8V, 7.4V, 8.4V(Bypass) by four-stage DIP switch. Therefore, additional device to measure the voltage is not required for voltage setting and everyone can easily and quickly set the voltage.
◆ Low voltage alarm circuit is embedded to guarantee user's convenience and safety. According to the type of battery or the preference, alarm voltage can be arbitrarily established(7.3V or 6.5V) and chosen whether or not to use.
◆ If the voltage of main battery falls below the voltage established for low voltage alarm, low voltage alarm circuit begin to operate. Both LOW/BATT LED display and buzzer on main unit are simultaneously active, external LED board(GDB-1010 option), mounted on the fuselage, distinguishable even in flight is equipped. Three high-luminance LEDs on external LED board quickly flicker on and off in the case of low voltage so that it is possible to immediately recognize low voltage alarm condition even in day long flight.
◆ There are input/output ports for four channels. Three servos for CCPM as well as throttle servo can supply the power optimized to servo specification(4.8V or 6.0V), and the voltage optimized to each servo even for system using 4.8V mixed with 6.0V servo.
◆ It is supported to use 7.4V HV servo. If output voltage is setup to 7.4V or 8.4V(Bypass), it is able to achieve more stable power supply and transient response than 7.4V battery direct connecting scheme to perform the buffer regulator function along with capacitor circuit.
◆ If the battery voltage is lower than the regulator setup voltage, safety accident from shut-down bypassing the battery voltage to the output voltage can be prevented.
4. Switch connection
Connect Fail-safe-on Pin-flag contactless switch to SW port of main unit. Three models of pin type(GSB-1010P), slide switch type(GSB-1010S), and connector type(GSC-1010) are supported, and user can choose one type depending his/her preference and convenience. Pin typed switch is supported as basic type at the factory. If Pin-flag on the switch board is pulled out, power is turned on.
☞ Switch board(GSB-1010P) could use double-sided foam tape or cable tie, or has a hole to fix with 3mm bolt in the middle of the switch board. Fix tightly with it.
☞ Contactless switch consumes very small current as standby current in off status. Therefore, a battery must be kept separate from connectors of a regulator for long term storage more than a month.
Caution and reference
5. Battery connection
Power input basically supports DINS connectors. Connect a battery to precisely check +/- polarity of male connector. At this time, if switch is on-state, short sound like 'peep' from buzzer could be listened(same as switch is on). This is the signal that low voltage alarm is normally operating. Female connector is the connector for charging and checking voltage. For dual battery, user would exchange female connector for male connector to connect the battery.
☞ Must be careful with polarity during exchanging connectors. If +/- polarity of a battery is inversely connected, internal circuit should be destroyed.
6. Receiver & Servo channel connection
Connect four JR typed female-female extension cable enclosed in the product to the channel of the receiver and the RECEIVER channel of the regulator. The regulator supplies 5.2V of power to the receiver via connected cable, and receives the signal of corresponding channel to bypass to the servo channel of the regulator in return. The servo connects to the servo channels of the regulator corresponding to 1~4 channels. As a result, the connection for the reboost power bus scheme that the servo is supplied the power from the regulator and the signal from the receiver is completed.
☞ Power(5.2V) to output to the receiver and power(5.2~8.4V) to output to the servo channel are independent circuits to completely separate. Thus, if the receiver is improperly connected to the servo channel of this product mixed with cables of the gyro or governor, the failure of the devices could be occurred so that it must be careful.
7. Using AUX channel
Use to connect the LED board(GDB-1010 option spec) for low voltage alarm. In addition, if +/- terminals of AUX terminal is used, the same voltage as the servo channel could be additionally used.
