5. Setup and Installation
5.1 Physical Installation and Dimensions
The XY7025 module and control panel are designed for integration into various enclosures or setups. Refer to the dimensions below for proper mounting and opening sizes.
Figure 5.1: Product dimensions for the XY7025 module and recommended opening size for the control panel.
- Main Module Dimensions: Approximately 111mm (L) x 72mm (W) x 43mm (H).
- Control Panel Dimensions: Approximately 86mm (L) x 50mm (W) x 40mm (H).
- Recommended Opening Size for Control Panel: Approximately 81.6mm (L) x 40.6mm (W).
5.2 Electrical Connections
- Input Power Connection: Connect your DC input power source to the "IN+" and "IN-" terminals on the main module. Ensure the input voltage is within the acceptable range (e.g., 8V-60V for a 70V output, typically input must be higher than desired output for step-down).
- Output Load Connection: Connect your load to the "OUT+" and "OUT-" terminals. Observe polarity.
- Control Panel Connection: Connect the ribbon cable from the control panel to the corresponding header on the main module. Ensure correct orientation.
- Grounding: For safety and stable operation, ensure proper grounding if applicable to your setup.
Note: Always double-check all connections before applying power. Incorrect wiring can damage the device or connected equipment.
6. Operating Instructions
6.1 Powering On/Off
- Power On: After all connections are secure, apply input power. The control panel display should illuminate.
- Power Off: Disconnect the input power source.
- Output Enable/Disable: Press the ON/OFF button on the control panel to enable or disable the output. When disabled, the output voltage will drop to zero.
6.2 Setting Voltage and Current
The XY7025 allows precise adjustment of output voltage and current limits.
- Setting Voltage (V-SET):
- Press the V-SET button. The voltage display will start blinking.
- Rotate the rotary encoder knob to adjust the desired output voltage.
- Press the rotary encoder knob to confirm the setting, or wait a few seconds for it to auto-confirm.
- Setting Current Limit (I-SET):
- Press the I-SET button. The current display will start blinking.
- Rotate the rotary encoder knob to adjust the desired maximum output current. This acts as a current limit.
- Press the rotary encoder knob to confirm the setting, or wait a few seconds for it to auto-confirm.
- Switching Display Modes (SW):
- Press the SW button to cycle through different display modes, such as input voltage, output power, etc. (Specific modes may vary slightly).
6.3 Constant Voltage (CV) and Constant Current (CC) Modes
The XY7025 automatically operates in either Constant Voltage (CV) or Constant Current (CC) mode:
- CV Mode: When the load current is below the set current limit, the power supply maintains the set output voltage. The "CV" indicator on the display will be active.
- CC Mode: When the load current reaches the set current limit, the power supply automatically reduces the output voltage to prevent the current from exceeding the limit. The "CC" indicator on the display will be active. This protects both the power supply and the connected load.

9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display/No power output | No input power; Incorrect wiring; Blown fuse (if applicable) | Check input power source and connections. Verify wiring polarity. Inspect for internal fuse if accessible. |
| Output voltage is lower than set | Operating in Constant Current (CC) mode; Input voltage too low; Overload | Check if the CC indicator is active. Reduce load current or increase current limit. Ensure input voltage is sufficient. Reduce load. |
| Output current is lower than set | Operating in Constant Voltage (CV) mode; Load resistance too high | Check if the CV indicator is active. The current is limited by the load. Ensure load is connected correctly. |
| Device overheats | Insufficient ventilation; Excessive load | Ensure proper airflow around the module. Reduce the load or operate within specified power limits. Consider active cooling if necessary. |
