Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing embodiment:
Fig. 1 is the circuit diagram of the utility model one embodiment.
Embodiment
As shown in Figure 1, the circuit diagram of the utility model one embodiment.
Present embodiment, a kind of pressure regulation charger comprises transformer T1, and this transformer T1 comprises a primary coil and one group of secondary coil, and this primary coil has a common port and some taps; The tap changer 20 that one hilted broadsword is thrown more; The movable end of this tap changer 20 is connected the alternating current input with common port, namely connect to exchange end 1; This tap changer 20 has some stiff ends and tap corresponding and connection one by one; Also have a charging module 30, this charging module 30 is connected in secondary coil, has the charging end 32 of exportable full-wave rectification charging signals.
In actual the use, charging end 32 same polarities are connected in the storage battery that is recharged, be communicated with then and exchange end 1 in civil power, tap changer 20 is begun to regulate gradually from the tap away from common port, charging end 31 voltages are risen, conform with the specified charging current of current storage battery up to the current value of electric current gauge outfit 60 and can begin charging.As seen, this device can charge at the numerous storage battery of specification, can adapt to by simple adjusting, and is simple in structure, easy to use.
