the auxiliary starter is designed to assist in starting and charging 12 V or 24 V lead batteries in vehicles such as trucks and construction machinery, and in starting internal combustion engines if the battery is fully drained or the ambient temperature is very low. The rectifier is equipped with a heat switch that turns the system off when the transformer overheats. Class 630 has a timer that automatically turns the device off after the set time, thereby preventing the battery from overcharged during quick charging. It is perfectly suitable for assisting the start-up of vehicles with petrol and diesel engines such as trucks, vans, agricultural machinery etc.Product characteristics:rapid charging option clear LCD timer to prevent overcharge of batteries to enable engine start-ups with fully drained batteries with capacity between 20 and 1550 Abrasion voltage 12V / 24VTechnical data: Power supply voltage: 230V, 50Hz Charging voltage: 12V/24VMaximum charge current: 12 V - 60 A; 24 V - 90 AStart current: 12 V - 360 A; 24-550 ASulake: 3x50Actuated battery capacity: 20-1550 AhRecital directional cables length: 150 cmSurface cable length: 200 cm
