Delta Electronics H60SB Non-Isolated DC/DC Converters

Delta Electronics H60SB Non-Isolated DC/DC Converters solve for applications where a regulated output voltage (adjustable) is needed from a widely varied input voltage source. These converters have an adjustable output current limiting function that supports a battery-charging circuit. H60SB converter modules provide a single output voltage which is adjusted over a wide range (0 to 60VDC). The input voltage range is 9VDC to 60VDC, and the output current is up to 50A. The peak efficiency of this standard half-brick DC-DC converter is up to 98%, allowing for DC-to-DC voltage conversion for output power up to 3000W. These Delta Electronics converters come with a host of industry-standard features like overcurrent protection, overtemperature protection, input UVP, and pre-bias startup input reverse polarity protection. Delta Electronics H60SB series units can be connected in a parallel application for higher output power without external Oring-fet. These DC-DC converters are ideal for battery charging, optical transport, data networking, server, and communication applications.
