DB

The DB series of high efficiency dc/dc converters are available as single, dual, or triple output versions, with up to 40 watts of output power. This product is ideal for telecom and networking applications, and is designed for a 2:1 input range, either nominal 24VDC (18VDC-36VDC), or nominal 48VDC (36VDC-75VDC). They are also PCB mountable, with a form factor of 2″ x 2″ x 0.4″, and incorporate six sided shielding. Standard specifications include Pi input filter, excellent load regulation, remote on/off capability, and short-circuit protection. The isolation voltage meets telecom requirements of >1500VDC.

● High Efficiency up to 90% ● Fixed Switching Frequency ● Six-Sided Continuous Shield ● 2:1 Wide Input Voltage Range ● 40 Watts Maximum Output power ● Standard 2.02” x 2.02” x 0.4” Package ● International Safety Standard Approval ● Single, Dual, Dual Positive (Total Output Current 8A), and Triple Outputs Available
