EC3SCW-48S12
Cincon EC3SCW-48S12 isolated DC-DC converter, 30 W, 4:1 18-75 V input and a regulated 12 V output at about 91 percent efficiency in a 2x1 inch case.
The EC3SCW-48S12 is a Cincon EC3SCW series isolated DC-DC converter rated at about 30 W with a 4:1 input range of about 18 V to 75 V DC and a single regulated 12 V output at up to about 2.5 A, in a 2x1 inch six-sided shield metal case. The 4:1 input range covers a 48 V telecom bus or a wide industrial supply, and the isolation of about 1500 VDC separates the input and the output for safety and noise immunity. The module reaches an efficiency of about 91 percent with a fixed 300 kHz switching frequency, it provides a regulated output with a continuous short-circuit protection and a no-load input current of only about 40 mA, and it meets the IEC/EN/UL 62368-1 safety standard. The shielded 2x1 inch case gives a good thermal and EMC behavior and an industry-standard pin-out, so the part fits a telecom board or an industrial card that must derive a larger isolated rail from a 48 V bus. Typical applications include telecom and datacom, industrial control, power distribution and a higher-power industrial card. Every module BeiLuo ships is factory-traceable and includes an import declaration, a certificate of origin and a RoHS compliance file. Our FAE team helps you choose the module and plan the layout and the filtering.
FAE Professional Review
The EC3SCW-48S12 gives an isolated 12 V rail at about 30 W from a 48 V bus with a 4:1 input range, a shielded 2x1 inch case and an efficiency of about 91 percent, so it suits a telecom or an industrial card that needs a larger rail. The low no-load current and the protection are useful for a continuous design. Keep the input capacitor close and follow the filter guidance.

Frequently Asked Questions
What projects suit the EC3SCW-48S12?
It suits a telecom board or an industrial card that must derive an isolated 12 V rail at about 30 W from a 48 V bus, with a 4:1 input range, a shielded case and an efficiency of about 91 percent.
Confirm the power and the isolation.
How do I keep the emissions low?
The six-sided shield and the fixed 300 kHz switching help, but plan the input filter and the layout as well: keep the input capacitor close, keep the switching loop small and follow the recommended filter. Confirm the conducted emissions with the real load.
Our FAE team can review the EMC.
