The MPS-1800S Series are single-channel high-power DC power supplies, including models like MPS-1800S-30-60 and MPS-1800S-60-30. They offer output voltages ranging from 0-30V to 0-300V, currents from 0-60A to 0-6A, with a consistent power of 1800W. Utilizing PWM modulation and high-gain amplifier circuits, they deliver strong stability. A 5-digit display shows voltage and current simultaneously, and front-panel preset buttons allow precise, convenient parameter setting. Equipped with OVP, OCP, OTP, and short-circuit protection, along with a keypad lock function, the series uses imported core components to ensure long-term full-load operation. It supports remote voltage compensation for accuracy, comes with standard RS-232/RS-485/SENSE interfaces, and optional analog signal interfaces. Input specifications: Single-phase AC220V±10% (50Hz). Ripple: ≤0.2% FS+50mVrms; dynamic response time: ≤5ms. Dimensions: 215×360×88mm; weight: 5.5KG. Suitable for high-power testing and industrial power supply scenarios. Additional features include an intelligent temperature-controlled fan and high-density fin radiators for efficient, low-noise heat dissipation, plus a memory function that automatically saves preset parameters on shutdown for hassle-free reuse.
