Product overview
The ZAC50 series is a high-precision, fast-response power supply with stable frequency and voltage regulation. It delivers pure and stable voltage waveforms even under complex grid conditions including unstable voltage/frequency, severe distortion, flicker, and voltage sags. This solution protects high-precision equipment from grid disturbances while overcoming the frequency-stabilization limitations of conventional parameter regulators, making it an ideal replacement for traditional voltage stabilizers.
● Wide input voltage range: can adapt to the rated voltage range of ±18%~±25%;
● High overload capacity: power unit is modular, can withstand more than twice the rated current without voltage drop;
● Fast dynamic response: sudden load voltage transient change <1%, recovery time <20ms;
· Good man-machine interaction: 7-inch touch operation display with resolution of 800*480;
● Strong anti-interference: optical fiber drive control, with strong anti-electromagnetic interference and reliability;
● High protection level: the surface of the equipment cabinet is treated with electrostatic spraying, and the PCB is treated with anti-corrosion paint and resin injection.
