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.

!Operation notes
(1) Output current should be reduced with increasing ambient temperature.
(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.
