Manual do usuario da fonte de alimentación CC de 3 canles MATRIX MPS-3010H-3C

1. Produto rematadoview

The MATRIX MPS-3010H-3C is a high-precision, 3-channel adjustable DC power supply designed for various applications including laboratory work, electronic repair, and DIY projects. It features two adjustable channels (CH1 and CH2) providing 0-30V / 0-10A each, and one fixed 5V / 3A channel (CH3), with a total power output of up to 615W. The unit offers a 4-digit bright screen display for voltage and current, independent control for CH1 and CH2, and supports 110V/220V input voltage conmutación.

Key features include high precision (0.03% + 10 mV, 0.1% + 5 mA) and stability with 10 mV, 1 mA resolution and low ripple (2 mVrms, 5 mArms). It incorporates a power-on slow-start circuit for stable and accurate DC output. The power supply allows for easy switching between independent, series, and parallel modes with a single button, eliminating the need for manual wire reconnection. It also supports presetting current and voltage without short circuits. User-friendly features include precision encoder adjustment knobs for accurate value changes, OCP/OVP/OTP protection, an intelligent fan system, and USB, RS-232, and RS-485 interfaces for computer or automated device connectivity.

5. Guía de configuración

5.1 Desembalaxe e colocación

Remove the power supply from its packaging. Place the unit on a stable, level surface with adequate space around it for ventilation. Ensure that the front and rear panels are easily accessible.

5.2 Conexión de alimentación de CA

1. Locate the AC input socket and the AC selector switch on the rear panel of the power supply.
2. Importante: Before connecting the power cord, ensure the AC selector switch is set to the correct voltage (110V or 220V) for your local power grid. Incorrect setting can damage the unit.
3. Connect the provided AC power cord to the AC input socket on the rear panel.
4. Conecte o outro extremo do cable de alimentación de CA a unha toma de corrente con conexión a terra.

5.3 Connecting Load

Use the provided test leads to connect your load to the output terminals. Ensure correct polarity (red for positive, black for negative). For CH1 and CH2, use the corresponding output terminals. CH3 (fixed 5V) also has dedicated output terminals.

6. Instrucións de funcionamento

6.1 Panel frontal rematadoview

The front panel provides all necessary controls and displays for operating the power supply.

• CH1 V, A display: Digital displays for Voltage and Current of Channel 1.
• CH2 V, A display: Digital displays for Voltage and Current of Channel 2.
• CH1 Adjustment knob: Encoder knob for setting Voltage and Current for Channel 1. Push to switch between coarse/fine adjustment.
• CH2 Adjustment knob: Encoder knob for setting Voltage and Current for Channel 2. Push to switch between coarse/fine adjustment.
• Indicador de modo: Lights indicating CC (Constant Current) or CV (Constant Voltage) modo.
• Menú: Button for accessing menu options.
