Precision regulated power supply frequency stabilization navigation Keywords: precision power supply, AC - DC - AC supply voltage frequency stabilization, frequency stabilization clean, power supply [Features] ◆ Rated Capacity: 500VA- 2000KVA ◆ Input voltage: 130-280V / 265-495V (mains status according to special custom range) ◆ Input Frequency: 20-100HZ (based on market conditions - can be specially customized range) ◆ Output voltage: 220V / 380V ± 0.5% ◆ Output frequency: 50 / 60HZ ± 0.01% ◆ Waveform distortion: ≤ ± 2% ◆ isolation transformer output, safe and reliable, to adapt to any unbalanced load, each phase can be used independently; ◆ efficiency up to 90%, using a wide load, for inductive, capacitive, resistive and so any mixed load; ◆ fast dynamic response, 0-100% load change, the steady-state response time is less than equal to 20%; ◆ use the ability of the natural environment, good anti-jamming ; ◆ Input passive filter, effectively improve the quality of power supply; ◆ dual-loop control, high impact resistance, excellent load capacity; ◆ independent electrical parameters of table show actual real-time measurement: Output frequency, output voltage, output current, output power and load power factor. [Application] ★ electrochemical industry: plating, etching, forming, can be used for electronic aluminum foil, chlor-alkali, carbon, silicon carbide production; ★ industrial plating, electrolytic copper foil precision, low ripple hard chrome plating; ★ industrial metal surface electrophoretic coating and electrophoretic coating aluminum surface; ★ precision measurement, medical electronic equipment; ★ imported power electronic and electrical equipment; exports of electronic and electrical product testing; ★ CNC machine tools, textile, automated production lines; ★ for the generator plant support to form a high uninterruptible power supply system. Cause Power Problems arising: electricity power plants is a certain limit, at the time of peak load capacity exceeds its electricity sector must buck power supply, which leads to the formation of the entire grid voltage; low power consumption peak in When the load is light, which would make the grid voltage increases cause the entire grid formation of two over-voltage; when the power factor is too low, on the use of the electricity sector added or disconnect the grid power factor capacitor to adjust, then will the provoked a spike voltage grid. Reports from the laboratory: major cause of damage to the equipment is sophisticated electronic voltage surges, ie short (about 10ms) or long-term over-pressure, which accounts for 45.3% of all causes of damage, and lightning 9.4%, leaving the device is not working The reason is that the normal machine error voltage is too low, accounting for 87% of power spikes accounted for 9%. Usually one computer will encounter more than 120 times the average monthly power problem, a computer, a power problems both cause keyboard lock; hardware aging relatively minor adverse effects, it may also lead to complete loss of data or motherboard combustion and other more big accident.
