FEC30 DC-DC Converter up to 30 Watts DIP

The FEC30 DC-DC converters cover three input ranges: 9–18 V, 18–36 V, and 36–75 V DC. These correspond to nominal 12 V, 24 V and 48 V supply systems respectively. Each model is designed for one of these ranges, allowing the series to be used in a variety of battery-powered and distributed power applications.

The series offers a selection of fixed output voltages including 1.5 V, 1.8 V, 2.5 V, 3.3 V, 5 V, 12 V, and 15 V for single-output models, as well as ±12 V and ±15 V for dual-output models. Depending on the output voltage, the maximum output power per module ranges from about 9 W (for the 1.5 V versions) up to 30 W for the higher voltage models. Dual output units can provide up to ±12 V or ±15 V at 15 W per rail (30 W combined). This variety allows engineers to choose a converter that closely matches their load requirements without unnecessary overhead.

No. The FEC30 series is designed to maintain stable output regulation down to 0% load. In other words, it does not require a minimum load current to stay within its specified performance. This is beneficial for systems that have light load or no-load operating periods, as the output voltage will remain regulated even when the load is very small or temporarily disconnected.

FEC30 DC-DC converters are certified to IEC/UL/EN 62368-1, which is the safety standard for ICT and AV equipment (covering industrial, telecom, and computer applications). They carry the necessary markings (such as CE) indicating compliance. The 1600 VDC isolation barrier and rigorous design testing ensure that these converters meet safety requirements for reinforced insulation in their intended applications. (Additionally, the manufacturer provides certification documents for reference.)

The FEC30’s six-sided continuous metal shielding greatly reduces the emission of electromagnetic interference (EMI) from the converter. By enclosing all sides of the module, it prevents most radiated noise from affecting nearby sensitive circuits, and also helps protect the converter from external interference. This feature makes it easier to meet EMC regulations at the system level. In practice, you should still follow good layout practices (like input/output filtering and grounding) to minimize noise. The manufacturer offers an EMC considerations document specific to the FEC30 series, which provides guidelines on input filters and recommended external components to ensure compliance with standards like EN 55032 for EMI.

Each FEC30 converter is galvanically isolated to 1600 VDC between the input and output. This high isolation rating is important for both safety and noise reasons. It protects the low-voltage output side from any high potential on the input side, which is crucial in systems where the input might be a higher voltage or not grounded the same as the output. The isolation allows the converters to be used to break ground loops and to provide a stable, noise-free supply to sensitive electronics even if the input power source is noisy or ungrounded. It also meets safety isolation requirements, meaning the device can be used in certified systems where insulation barriers are needed for operator protection and equipment integrity.

The FEC30 series achieves high efficiency, with typical efficiency ranging from around 78–85% for the lowest output voltages up to roughly 88–90% for the higher voltage models at full load. In practical terms, a higher efficiency means less power is lost as heat within the converter. For example, a 30 W module at 90% efficiency dissipates only about 3 W of heat (whereas at 80% efficiency it would dissipate 7.5 W). Because the FEC30 modules are relatively efficient, they generate less heat and put a smaller thermal load on your system. This simplifies cooling requirements – often natural convection is sufficient, though at maximum load and higher ambient temperatures, some airflow or heatsinking may be needed to keep the module within safe operating temperatures.

Yes. The FEC30 modules include a remote ON/OFF control pin. By default this uses positive logic, meaning the converter is enabled when the control pin is left open or driven high (within a specified voltage range), and it can be disabled by pulling the pin low (toward 0 V) or shorting it to the module’s ground. This remote control feature allows you to switch the output of the converter on or off electronically, which is useful for power sequencing or for reducing system power consumption when certain loads are not needed. The control input draws minimal current, and the exact logic thresholds are provided in the datasheet. Using the remote ON/OFF pin does not affect the isolation between input and output.

FEC30 converters are designed for industrial, transportation, telecom, and IT applications where a stable isolated supply of up to 30 W is needed. Typical use cases include powering communication modules, control systems, embedded computing boards, sensors and instrumentation, and other electronics from a distributed DC bus. For example, in telecom infrastructure the 48 V battery bus can be converted down to logic-level voltages using an FEC30 module. In industrial automation, a 24 V supply rail can feed various control circuits via these converters. The wide input ranges and robust design (with an encapsulated, shielded package and wide operating temperature capability) mean the FEC30 series performs well in environments with variable supply voltages, electrical noise, and harsh ambient conditions. Engineers choose these modules when they need reliability, safety isolation, and flexibility in a compact power solution.
