1. Produit terminéview
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 commutation.
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.
