XY8030S XY12530S CNC Step-Down DC Adjustable Stabilized Voltage Power Supply User Manual

1. Introduction

This manual provides detailed instructions for the setup, operation, maintenance, and troubleshooting of the DIY NOW XY8030S and XY12530S CNC Step-Down DC Adjustable Stabilized Voltage Power Supply modules. These modules are designed for applications requiring precise constant voltage (CV) and constant current (CC) output, with advanced features like MPPT solar charging, serial communication, and comprehensive protection mechanisms.

The XY8030S model offers up to 2400W output power, while the XY12530S model provides up to 3750W. Both models feature a 1.8-inch full-view high-brightness true color LCD screen with customizable color schemes and 4-way rotation support for enhanced usability.

2. Setup

2.1 Unpacking and Inspection

Carefully unpack the power supply module and inspect it for any visible damage. Ensure all components listed in the package are present.

2.2 Physical Dimensions and Mounting

The bare board dimensions are approximately 138mm x 92mm x 45mm (H). The recommended opening size for panel mounting is 81.6mm x 40.6mm. Ensure adequate space for ventilation, especially around the dual cooling fans.

Figure 1: Product dimensions and recommended opening size for panel mounting.

2.3 Wiring Connections

Refer to the wiring diagrams for proper connection of input, output, and optional components like the external temperature probe and communication modules.

Figure 2: Internal components and wiring points (IN+, IN-, OUT+, OUT-, Power switch, MPPT switch, NTC temperature sensor interface, GND, RX, TX, 5V).

Figure 3: Wiring diagram for solar charging with MPPT and external temperature probe. Precaution: Ensure the unit is OFF before connecting the battery. Avoid reverse polarity connection to prevent device damage or fire hazards. Turn on the output ONLY after the battery icon appears on the screen to initiate charging.

2.3.1 Bare Board Specifics

For bare board versions, switches, potentiometers, and dial switches are typically welded on. If a set with a screen meter is purchased, these components are not welded by default.

Figure 4: Bare board features, wiring diagram, and dip switch settings for current adjustment. The output voltage is adjustable from 0-85V, and the output current is adjustable from 0-30A. Analog control (0.3-10V) is available in numerical control screen mode. The dip switch allows setting constant current values in 16 gears.

2.4 Communication Setup

The module supports independent dual serial ports, serial port TTL, and on-board 485 communication. It can be connected to a WiFi module for remote control via APP/web or an infrared remote control module.

V-SET (Short: Set voltage CV, Long: Call M1 data set), SW (Short: Quick settings, Long: 4-way screen rotation), I-SET (Short: Set current CC, Long: Enter/exit data group settings), Encoder (Short: Shift, Long: Lock button), Power (Short: Output on/off, Long: Shut down).

3.2 Setting Voltage and Current

There are three methods to set voltage and current:

1. Quick Setup Mode:
   1. Briefly press the V-SET/I-SET button to enter voltage/current setting mode.
   2. Use the SW button or encoder button to move between digits.
   3. Rotate the encoder to adjust the voltage/current value.
   4. Once set, briefly press V-SET/I-SET to save and exit.
2. Encoder Mode:
   1. Briefly press the encoder button to activate the parameter (voltage/current) you want to set.
   2. Press the encoder button to switch between full selection and digit selection. In full selection, all digits are highlighted. Rotate the encoder to switch between setting voltage or current. In digit selection, the selected digit is highlighted. Rotate the encoder to adjust the value.
   3. To finish, either hold the encoder button/SW button for 2 seconds or wait 6 seconds without any button press. All settings are saved automatically.
3. Remote Control Mode:

   Use an infrared remote control or a 433M wireless remote control module to set voltage and current directly with the remote's numeric keypad.

3.3 Constant Voltage (CV), Constant Current (CC), and Constant Power (CW) Features

Figure 11: CV, CC, and CW Features Introduction.

1. Constant Voltage (CV) and Constant Current (CC):

   When the constant power function is not turned on, the power supply operates in CV and CC modes, automatically switching based on the load. If the load current is less than the set constant current value, the power supply is in constant voltage mode, where the output voltage is the set CV value, and the current is adaptive.

2. Constant Power (CW):

   After the constant power function is turned on, the constant current value defaults to the maximum. The constant voltage value (CV) serves as the initial voltage. The module calculates the equivalent resistance (R=U/I) and then the corresponding voltage based on the set constant power value (P=U*R). The constant power point algorithm automatically follows to achieve constant power.

3.3.1 Constant Power Switch and Value Setting

1. In the system parameter settings UI, select the CW option. Turn ON to enable constant power, and turn OFF to disable it.
2. After enabling constant power, briefly press ISET on the main interface to modify the constant power value.

3.4 Data Set Management

3.4.1 Quickly Recall Data Sets

• Recall M1 Data Set: Hold the V-SET button to quickly load the M1 data set.
• Select Data Set: Hold the I-SET button to open the data set selection window. Rotate the encoder to choose the desired data set. Then, either hold I-SET or briefly press the SW/encoder button to load the selected data set. The interface will display the currently loaded data set.

3.5 Adjusting System Parameters

3.5.1 Quickly Adjust System Parameters in the Status Bar

On the main screen, briefly press the SW button to select a status bar parameter. Rotate the encoder to switch between parameters. Briefly press the SW button or encoder button to adjust the parameter or open the parameter setting interface. Use the encoder to set the value. To save and exit, either hold the SW button/encoder button for 2 seconds or wait 6 seconds without any button press. All settings are saved automatically.

3.6 Screen Customization and Rotation

3.7.1 Activating Group Control Function

On the main power supply interface, briefly press the SW button to select the right status bar. Rotate the encoder to choose the group control switch activation icon, then briefly press the encoder button to open the selection dialog. Press the SW or encoder button to select and rotate the encoder to ON to enable group control mode. When setting voltage, current, or power on/off, the changes will automatically synchronize to all devices on the 485 bus (Note: Device addresses on the bus must be unique). Hold the SW button or wait 6 seconds without operation to exit and save settings automatically.

5.2 Common Issues

• No Output: Check input power, ensure output is enabled (green light on power button), and verify protection settings (OVP, OCP, etc.) are not triggered.
