Description

This series adopts microprocessor chip with fast respond, high-accuracy process control, making the inverter operating in four-quadrant, continuously feedback,and regenerative braking frequency below 40%. Electric regeneration efficiency up to 97%. Using SPWM modulation to greatly reduce distinctive peaks of current and form perfect sine wave current, input side current THD lower than 5%, power factor up to 99%.It can prevent power grid flowing back, overheating, overcurrent, out of phase, undervoltage,and short circuit. Characteristics: Power range:55KVA-110KVA Rated current: 150-200A Working DC power voltage: DC 620/1150V Output AC power voltage : three-phase AC 400/660V Chopper voltage: DC620V±5V/DC1150V±5V Operating frequency: 46-60Hz Accuracy index: setting error less than 0.5% Overload capability:110% long-term,150% 1min,180% 2s. Working conditions: containing built-in intelligent fan, high and low order harmonic filter, external short circuit protection. Protection class: IP20 Protection function: OCP,OVP,UVP,overheating protection and polarity protection. EMC: Accord with GB/T 17626.4( IEC61000-4-4)4 class EFT interference test;GB/T 17626.3( IEC61000-4-4)4 class radiation EMF test;GB/T 17626.2( IEC61000-4-4)4 class ESD test. Environmental ambient temperature: -10℃~+60℃(non-frozen) Ambient humidity: below 90%(non-frost) Altitude: less than 1km Cooling mode: forced-air cooling Installation method: wall-mounted, floor type Standard: ISO,FCC,CE Application: Dedicated for mine hoist, salvage ship, winch, forging equipment, oil-fieldpumping unit,crane, port crane, tower crane, high power cutter, etc
