How to use
VR Pro adopts a horizontal row as
input and output,(seethe rightpicture).
According to the label instructions, the
four sockets on the left are for servos.
The four sockets on the middle are
connect to the receiver with the output
wire (#46815). The four sockets on the left correspond one to
one to the four sockets on the middle. This design has the
advantage of plugging the largest power consumption servos in
VR Pro Duo to reduce the receiver burden. Also solve the 4
output wires taking too many receiver channels problem.Two
sockets on the right side are respectively for fan and control
switch.
VR Pro Duo has two battery input
wires on the opposite side. It can be
connected with two batteries for power
supply. VR Pro Duo can also connect
1piece of battery for work.(We suggest
to use Dualsky 20C series 2S li-po
battery for VR Pro Duo) When these
wires are connected correctly, please remove the FSS-3 plug pin
to work.

During working, the built-in two monitors display the two
batteries voltage respectively. the built in tri-color monitors
display battery voltage: over 7.4V with green light, 7.4V to 7V
with yellow light, lower than 7V with the red light. When the red
light on, the user should stop using as soon as possible.The red
light warning has memory function, it indicates that the battery
has fault (low voltage, poor contact or system overload). Close
the switch and re-open it can reset the memory. When one
battery fails, the system will switch to another battery to work
automatically. This enhances the safety of power supply greatly.
In normal operation, FSS-3 power indicator always lights, if
any power failure ( low battery, overload or bad connection), it
will enter the alarm mode, the lights will flicker, this mode also
has memory function. Power off and eliminate the malfunction.
Power on again to restore the normal status.
FSS-3 power switch, FSS-4 power switch (optional), the
voltage display circuit and output voltage select switch are all
using the "fail safe" design. Any fault will not take the initiative
to turnoff VR Pro Duo power output. When the voltage select
switch fails, the output voltage will be set to 5V.
● Not suitable for children under 14 years old without adult
guidance;
● Do not use it in the high temperature or humid environment;
● When using this product in strong vibration environment,
vibration mitigation measures should be used;
● Please remove the packing material before use VR Pro Duo;
● Since the output current is large, please use 4 output wires to
connect the receiver;
● This product supports switching voltage. Please select the
voltage according to the supply voltage of your receiver,
servo or other equipmentsl;
● Do not change the output voltage while VR Pro is working;
● Output port short circuit will damage VR Pro;
● In order to ensure the VR Pro Duo working properly, please
obey the following formula to limit the thermal power in a safe
range:
(1) (input voltage - output voltage) x output current < = 15W;
(2) Please pay special attention to that, if the VR Pro current
is over 15W for a long time, the temperature will rise
quickly, it will damage the regulator;
(3) When the cooling fan is mounted (#46816, optional), the
thermal power can be increased to 20W;
(4) VR Pro will not stop working when the input current is too
large. But the internal limit working temperature is 120
degrees. When the temperature is more than this limit, it
will damage the control IC.
● The two input batteries should be in the same specification
and same charge cycle;
● The voltage indication and alarm is preset according to the
lithium polymer battery;
● Notes: If you don't use the regulator in 24 hours, you'd better
disconnect it from the battery because it remains a 3mA
quiescent current.
Safety attentions
(Failure to follow these instructions can be damage your
product, and cause serious bodily injury or death.)

主要技术参数
使用说明：
VR Pro Duo 采用水平排针作为输出，
如右图。按稳压器标签指示，左边四个插口
(Servos) 连接 4 个通道舵机，中间 4 个插口
(Receiver)通过输出线（#46815）与接收机
相连。舵机插口号与输出插口号对应，舵机
对应通道就是对应输出线插在接收机上的通
道。此设计的优点在于可以将耗电量最大的
几个舵机连接在VR Pro Duo上，降低接收机工作负担。
同时解决了4路输出线占据过多接收机通道的问题。右边分别为风扇和控
制开关插口，只要对应连接即可。连接时注意插头凸起对应插口槽。

VR Pro Duo另一侧有两路输入电池连
接线，可以接两颗电池冗余供电。VR Pro
Duo也可以只接一块电池工作。建议采用2
组双天20C系列2S锂聚合物电池为VR Pro
Duo供电。旁边的3档开关可以选择输出电
压，档位分别是5V/6V/7.4V。上述连接确
认无误后，将FSS-3上的插针移除即可工作。
工作中，内置双路监视器分别显示两路电池电压：7.4V以上，绿灯亮，
7.4V-7V，黄灯亮，如果电压低于7V，红灯亮，此时应尽快停止使用。红
灯警告有记忆功能，表示该路电池曾经故障（电量低、过载或接触不良），
关闭电源消除故障后，重开方可恢复。一路电池故障，系统会切换另一
路电池维持正常供电，大大提升供电安全。
正常工作时，FSS-3电源指示常亮，一旦任何一路电源故障（电量低、
过载或接触不良），则会进入报警模式，指示灯开始闪烁，此模式同样
有记忆功能，关闭电源消除故障后，重开方可恢复。
FSS-3电源开关、FSS-4 (选配)、电压显示电路和输出电压选择开关
均采用Fail safe“失效安全”设计。任何故障不会主动关断VR Pro Duo
的电力输出。当电压选择开关失效后，输出电压被设定在5V。
● 本品不是玩具，14岁以下儿童使用需要有成人监护；
● 请勿在高温、潮湿的环境下使用；
● 在强烈振动环境使用本产品时，应做好缓振措施；
● 请勿将VR Pro Duo整个包裹后使用；
● 由于输出电流较大，请采用4根输出线连接至接收机；
● 本产品支持电压切换，使用此电压时，请确认你的接收机、舵机或其他
设备支持该电压；
● 不要在稳压器工作时切换输出电压；
● 输出端绝不可以短路；
● 为确保VR Pro Duo正常工作，请遵守下面的公式，将发热功率限制在
安全范围内：
（1）(输入电压 - 输出电压) x 输出电流 <= 15W；
（2）如果长时间大于15W，温度会快速上升，可能会损坏稳压器，请特
别注意；
（3）安装冷却风扇（#46816，选配件），热功率可以提升20W；
（4）VR Pro Duo不会因为输入电流过大而停止工作，但内部极限工作
温度为120度，超过控制IC将损坏。
● 两路冗余输入应采用相同规格和使用循环次数的电池；
● VR Pro Duo电压指示和报警按照锂聚合物电池预设；
● 如果你长时间（24小时内）不使用VR Pro Duo，请断开和电池的连接，
因为待机状态下也会有3mA耗电。
