BP5048 / BP5048-15 / BP5048-24 Power Module AC / DC Converter BP5048 / BP5048-15 / BP5048-24 The BP5048, BP5048-15 and BP5048-24 are AC / DC converters which can be used to supply DC output from a commercial power supply (200 to 220 V AC). Using these modules enable simple, easy drive of microcomputers, LEDs, and other electronic components without using a transformer. They also allow set PCBs to be kept compact and lightweight, with extremely few attachments. These products can accommodate the 200V AC power supplies used as household power supplies in Asia and Europe, as well as in buildings and facilities in Japan. !Applications Power supply circuits for vacuum cleaners, refrigerators, washing machines, air conditioners, irons, electric carpets, cordless telephones, air purifiers, humidifiers, dehumidifiers, home bakery devices, electric crock pots and rice cookers, illumination devices and other small household appliances, as well as power supply circuits for gas leakage sensors, and other industrial products !Features 1) Elimination of a transformer enables compact, lightweight power supply boards. 2) Wide input voltage range.(249 to 358V DC for DC voltage conversion) 3) DC power supplies can be easily configured, with few attachments. 4) Because no transformer is used, the power supply board is less vulnerable to splitting or cracking from impact or shock. 5) Allow easy assemblage of components. !List of the BP5048 series Power supply voltage BP5048 BP5048-15 BP5048-24 Unit 249~358 249~358 249~358 V Output voltage 12 15 24 V Output current 300 200 200 mA !Absolute maximum ratings (Ta=25°C) Parameter Power supply voltage Symbol Limits Unit VIN 358 V Operating temperature range Topr −20~+80 °C Storage temperature range Tstg −25~+105 °C !Recommended operating conditions (Ta=25°C) Parameter Symbol Min.

(2) Over current and shorted circuit The overcurrent protection circuit limits the current to about 330mA (BP5048), 240mA (BP5048-15), 230mA (BP5048-24) with drooping model. If there is any danger of the load being shorted or overcurrent being produced, always use a protective device such as a fuse. (3) Insulation These products are not insulated on the primary side, and there is a danger of electrical shock if they are touched. (4) Avoid subjecting these products to strong impact. (5) Lead pins should be securely connected. If lead pins are not securely connected, irregular voltages could be produced, causing breakdowns and damage.
