Forklift chargers, as the name suggests, are chargers specially designed for charging electric forklifts. Most chargers can be applied to electric trucks, electric lift trucks, electric pallet trucks, stackers, forklifts, golf carts, electric tour buses, and starting batteries on cars, tanks, and small and medium-sized generator sets.
Maintenance method: Check whether the input power plug of the forklift charger is well connected to the mains. You can try it by inserting the input plug of the forklift charger into a normal power outlet. If the situation remains the same, open the charger shell and observe the internal whether the fuse is broken, if not, first check whether the power input line is in good condition. After eliminating the fault of the power input line, you should check whether the components near the high-voltage area on the circuit board are soldered, and whether the fuse holder is in poor contact, focus on checking whether the transformer T1, triode V1, V2, etc. have the phenomenon of virtual welding. In addition, the open circuit of R5 or R6 will also cause the above faults. If the fuse in the machine is broken, you must not replace the high-ampere fuse tube (the fuse tube of the charger is generally 2A). Focus on checking whether D1-D4, V1, V2, R4, R7 and D15, D21 are damaged. If damaged, you can choose the same type of replacement. Please note that when the above components are damaged, one or two may be damaged at the same time, and sometimes several may be damaged at the same time. During maintenance, you need to check and replace these components one by one before powering on.
Maintenance method: The cause of the failure is the damage of the output stage vibration-absorbing resistor-capacitor R31 and C17. In addition, C12 open circuit or virtual welding can also cause the above faults.
Maintenance method: Check whether C8 on the circuit board is soldered or damaged. Generally, replacing C8 can solve this fault.
