Features:  This product supports the input and output of single power supply and dual power supply, and can be converted to each other. The following are supported:  1. Single power input, single power output.  2. Single power input, dual power output.  3. Dual power input, dual power output.  4. Dual power input, single power output.  This product supports the power input and output of the above four modes.     Specification:  Size: 119*51*19 mm (length * width * height).  Maximum peak voltage: 100V.  Maximum peak current: 12A.  Maximum peak power: 1200W.  The above is the limit data of this product. Do not use it beyond this specification or at full load to avoid danger. For safety reasons, it is recommended that the load side do not exceed 80% of the power of the power supply terminal and leave a margin. The output current and voltage of the board depends on the power of the front-end transformer (simple calculation is the voltage multiplied by the current).  The same transformer has different sizes, but the power is different. In fact, the output current is different (the wire diameter of the secondary coil determines).  In fact, it is better to have a larger power, leaving a margin, the transformer will not heat easily, and the transformer is smaller, that is, the pull cart we mentioned, when the load needs a large current, not only the transformer heats up, the output voltage will also drop, and the long-term full-load operation will shorten the service life of the equipment.  Therefore, we need to consider how much current the load needs, and the power supply provided must be greater than the required current, so that the power supply part can meet the load needs, only the power supply part can operate safely and will not be burnt out.  The front and rear input and output terminals of our module adopt large wiring terminals with safety cover plate, which can withstand large current and high voltage, the safety cover can also protect us from accidentally touching the terminal and being powered. This is safer and more reliable than small terminal blocks.  Our module uses four rectifier Bridge, which is more stable and reliable than single-Bridge rectification and double-bridge rectification. If the number is large, we can use small size, and we do not need a huge rectifier bridge with a cooling fin, suddenly put it there, which affects the appearance and the space of the chassis, and the overall size and specifications are more unified.     Package included:  1 x Dual Power Supply Rectifier Filter Module
