3. Safety Information
- Always ensure proper ventilation around the power supply during operation.
- Do not operate the device in wet or damp conditions.
- Ensure all connections are secure before applying power.
- When using the battery charging function, ensure you are familiar with battery safety. Non-professionals should exercise extreme caution or avoid this function due to potential risks of fire or explosion.
- The 800W PSU is typically configured for 220V AC input. If operating in a 110V AC region, ensure the input voltage selector switch on the PSU is correctly set to 110V to prevent damage.
- Do not attempt to modify the internal components of the power supply. Refer all servicing to qualified personnel.
4. Setup and Assembly
The RD6012W kit requires assembly of the module, case, and PSU. Follow the steps below for proper setup.
4.1 Component Integration
The RD6012W module, S800 case, and 800W PSU are designed for integrated assembly. Refer to the provided installation manual (PDF) or online assembly videos for detailed visual instructions.

4.2 Power Connection
- Connect the 800W PSU to a suitable AC power source using a standard AC power cable (not supplied).
- Important: Verify the input voltage setting on the 800W PSU. It is typically set to 220V AC by default. If your region uses 110V AC, adjust the voltage selector switch on the PSU accordingly before connecting to power.
4.3 CR1220 Battery Installation
Install a CR1220 battery (not supplied) into the designated slot on the RD6012W module. This battery powers the internal clock for time display functionality.
5. Operation
5.1 Basic Control and Display
The RD6012W features a keypad and rotary encoder for setting voltage, current, and other parameters. The LCD screen displays real-time output voltage, current, power, and other status indicators.

5.5 Protection Features
The RD6012W incorporates several protection mechanisms to safeguard connected loads and the device itself:
- Over Voltage Protection (OVP): Shuts down output if voltage exceeds a set limit.
- Over Current Protection (OCP): Shuts down output if current exceeds a set limit.
- Over Temperature Protection (OTP): Activates if the system temperature exceeds 80℃.

6. Maintenance
6.1 Fuse Replacement
The unit is equipped with dual fuses for protection. A backup fuse is typically included in the package. If a fuse burns out, you can temporarily use the backup fuse. For optimal performance and safety, it is recommended to replace any burnt fuse with a new one of the correct rating (e.g., 1808-20A-65V Fast Blow Fuse).

7. Troubleshooting
- APP/PC Software Incompatibility: Before purchasing, download the APP or PC software to verify compatibility with your operating system (Android 5.0+, iOS 10.0-13.4, Windows 7+). Incompatibilities may occur with certain phone or PC systems.
- Wi-Fi Connection Issues: The Wi-Fi communication module supports only 2.4GHz signals. Ensure your router is configured to broadcast a 2.4GHz network and your mobile device is connected to it. 5GHz networks are not supported.
- No Time Display: Ensure a CR1220 battery is correctly installed in the module to enable the time display function.
- No Power Output: Check all power connections, including the AC input to the 800W PSU and the connections between the PSU and the RD6012W module. Verify the PSU's input voltage switch is set correctly (110V or 220V). Check if any fuses have blown.
- Device Overheating: Ensure adequate ventilation around the unit. If the Over Temperature Protection (OTP) activates, allow the unit to cool down before resuming operation.
- Persistent Issues: If you encounter problems not covered in this section, please contact customer support for assistance.
