About Tumo-Int 2000W Low Frequency DC 24V To AC 120V Pure
Low Frequency versus High Frequency Inverter This low frequency inverter charger use high speed power transistors to invert the DC to AC, but drive transistors at the same frequency (60Hz or 50Hz) as the AC sine wave output. High frequency power inverters typically drive the transistors at a high frequency closer to 50KHz or higher. When delivering the same amount of power, for example, the 6KW low frequency inverter transformer outputs more power at each cycle, so it is required to work harder, resulting in larger and heavier transformer and package. In contrary, a 6Kw high frequency inverter delivers less power at each cycle, allowing for a smaller and lighter transformer and package. In general low frequency inverters are far superior for starting difficult loads. ie. motors. Hence, low frequency inverters are more suitable for household such as refrigerator or air condition. Pros of Low Frequency Inverter ●Stronger over load capacity ●Stronger to input surge ●Stronger output impact resistance ●Stronger short-circuit ability ●Better voltage between zero and ground line ●Less output level components ●Bigger power devices capacity ●Lower device damage when faults ●More reliability and simple maintainability Basic Specification: Rate DC input: 24VDC Utility AC input: 75~135VAC Charging current: 15~25A Rated output power: 2000W Stable output voltage: 120/220V±3% Output frequency: 50/60Hz±3% Efficiency: ≥85% Protection class: IP30 THD: ≤3% Overload: 120%10min, 150%1min Work temperature: -20℃~50℃ Communication port: RS232/R11/J45 (optional) Packing List: 1*Tumo-Int 2000W Pure Sine Wave Inverter Charger 1*User Manual
