Precision voltage constant frequency power supply

Features supply voltage frequency stabilization; This product is a grid supply voltage, supply frequency are unstable voltage distortion serious case of the presence of flicker voltage drop and other comprehensive quality problems, to protect the grid sensitive equipment. supply quality power electronic devices. The power supply can solve all issues other than the power to provide you with a voltage, frequency is extremely stable waveform extremely clean power environmental standards and to overcome the shortcomings of UPS can not with inductive load can be applied to any load. Application: 1. railway, aviation, navigation system 2. The precision test medical electronic equipment 3. Imported electronic and electrical equipment supply 4. export of electronic and electrical product testing 5. CNC machine tools, textile, automated production lines 6. Generator Plant supporting high performance uninterruptible power supply system is mainly composed of technical parameters: ◆ Input voltage: 130-280V / 265-495V ◆ input frequency: 30-80HZ ◆ Output voltage: 220V / 380V ± 0.5% ◆ Output frequency: 50HZ ± 0.01% ◆ Waveform distortion: ≤ ± 2% ◆ isolation transformer output: safe and reliable adapt to any unbalanced load, each phase can be used independently. ? With the output high voltage. Overcurrent. Overload. Overheat short circuit protection and automatic alarm reaction speed. Ensure that no damage to the electrical equipment when the power supply output failure. ? Efficiency up to 90% for wide loads, for inductive, capacitive, resistive, and any mixed load. ? Fast dynamic response, 0-100% load change, the steady-state response time <20ms. ? Ability to adapt to the natural environment, good anti-jamming. ? Input passive filter, effectively improve the quality of power supply. ? Patented dual-loop control, high impact resistance, excellent load capacity.
