●This product supports switching voltage. Please select the voltage according to the
supply voltage of your receiver, servo or other equipment.
●Do not change the output voltage while VR mini is working.
●Output port short circuit will damage VR mini.
●Input voltage higher than 10V will damage VR mini.
●Please do not cover VR mini while using it.
●Do not use VR mini in high temperature or humid environment.
●When using this product in strong vibration environment, vibration mitigation
measures should be used.
●The voltage indication and alarm is preset according to the lithium polymer battery.
●If you don't use the regulator in 24 hours, you'd better disconnect it from the battery
because a 4mA quiescent current draw remains.
●Not suitable for children under 14 years old without adult guidance.
2. Select output voltage: You can select the output voltage by the DIP switch on the
back side of VR mini. As shown in the below picture, there are 4 different voltage
you can set.
3. Failsafe port: This port can connect to Dualsky FSS switches. Output voltage will
be cut off when the FSS switch turned on. This port can also be used to connect 2A
high-power LED indicator to display the battery status. When battery voltage is
higher than 7.4V, LED will remain lit. When battery voltage is between 7 -
7.4V, LED will flash twice a time. When battery voltage is lower than 7V, LED will
flash once a time. Please stop using as soon as the single flash start. Single flash is
a memory status, indicated that battery has problem (low voltage, bad contact or
overload). Turning off the FSS switch can clear up the memory.
4. FSS-4 switch, the voltage display circuit and the output voltage select switch are all
using the "fail safe" design. Any fault will not take the initiative to turnoff VR Mini
power output. When the voltage select switch fails, the output voltage will be set to
5V.
If you use VR mini on electric RC airplanes, please disable the BEC function in
ESC. You can do it by disconnect the BEC positive pole wire as shown in the below
picture. Switch on the FSS-4, VR mini will start to work immediately.

如果模型为电动飞机，采用VR mini后，需要禁用ESC的BEC功能，可以通过断开
BEC的正极线来禁用，如下图。打开FSS-4开关，VR mini立即工作。
2.电压调节：可以通过VR mini背面的DIP开关调节输出电压，通过不同DIP开关位置，
可以设定5V，6V，7.4V和直通4种电压等级。具体设置如下图：
3.Failsafe接口：该接口可以连接双天的FSS开关，开关接通输出电压被关断，同时该
接口具有驱动2A大功率LED指示灯的功能，用于显示电池电压状态，当电压高于
7.4V时，连接在该接口的LED处于长亮状态，当电压在7.4V到7V之间时，连接在该
接口的LED处于双闪状态，当单体电压低于7V时，连接在该接口的LED处于单闪状
态，此时应尽快停止使用。单闪警告有记忆功能，表示电池曾经故障（电量低、
接触不良或系统过载），关闭开关后重开可以消除记忆。
4.FSS-4电源开关、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 mini的电力输出。当电压选择开关失效后，输出
电压被设定在5V。
1.输入输出接线：VR mini在出厂时已经为客户焊接好输入输出线，如外壳标签所示，
左边为输入线，右边为输出线。输入线接电池，输出端连接接收机，给接收机、
飞控等电子设备供电，如下图：
