MGFS302405-G Présentation
An isolated DC-DC converter module is a self-contained power supply block that uses an internal transformer (galvanic barrier) to break the DC ground path between the source and load, providing safety isolation and noise immunity. Within the broader power-management hierarchy, a board-mount isolated module is a sub-category of DC-DC converters and switching regulators, sitting above discrete buck/boost converter designs in terms of integration level. The MGFS30 family targets the 15 W to 30 W tier where most industrial 5 V auxiliary rails operate.
Key features of the MGFS302405-G include 30 W continuous output power, 6 A maximum output current, 90 % typical efficiency at nominal line, and a wide 9 V to 36 V input window that covers 12 V and 24 V industrial bus rails. The 1.5 kV DC input-to-output isolation satisfies reinforced-isolation requirements for industrial control and ITE equipment. The through-hole 6-pin brick package provides robust mechanical attachment and natural convection cooling up to the rated power.
Internally the module uses a fixed-frequency isolated flyback-forward topology with synchronous rectification on the secondary, which explains the high 90 % efficiency at 24 V input. Integrated input filtering, soft-start, and over-current / over-temperature protection reduce the external component count to just input/output capacitors. The output voltage is factory-trimmed to 5 V ±2 %, eliminating the need for an external adjustment resistor.
Typical applications include industrial PLC and sensor 5 V rails, factory automation I/O power, isolated 24 V-to-5 V bus converters, test-and-measurement front-end power, and ITE equipment requiring a regulated isolated 5 V supply. The wide 9 V to 36 V input allows a single part to cover both 12 V and 24 V nominal buses, simplifying BOM.
When designing with this part, observe the derating curve above 60 °C and provide at least 2 mm clearance around the through-hole pins to meet the 1.5 kV isolation rating. A 22 µF input capacitor and a 100 µF output capacitor are recommended to suppress reflected ripple and load-step transients. Mount the module vertically on the PCB with the baseplate flush to maximize convection cooling.

Applications typiques
MGFS302405-G convient pour 6 applications: Industrial PLC 5 V Auxiliary Rail, Factory Automation I/O Power, Isolated 24 V to 5 V Bus Converter, Test and Measurement Front-End Power, ITE Equipment Regulated 5 V Supply, Isolated Power for Communication Gateways.
Industrial PLC 5 V Auxiliary Rail
The MGFS302405-G is well-suited to supply 5 V logic rails inside industrial PLCs because its 9 V to 36 V input natively accepts both 12 V and 24 V PLC backplane voltages without external front-end regulation. The 1.5 kV DC isolation breaks ground loops between field-side 24 V sensors and the controller's 5 V digital core, protecting downstream microcontrollers (such as the XAIPART-listed LPC4330FET256 or MC9S12D64CPVE) from field transients. Placed near the controller's 5 V input pin with a 100 µF output bulk and 10 µF ceramic, the module delivers clean, isolated 6 A headroom for I/O expansion modules. At 90 % typical efficiency the converter dissipates only ~3.3 W at 30 W output, fitting comfortably inside sealed PLC enclosures without active cooling.

Factory Automation I/O Power
In factory-automation I/O nodes the MGFS302405-G converts a 24 V field bus into a regulated isolated 5 V rail for sensor aggregation and communication ASICs. Its 30 W budget supports powering a multi-channel digital-input board plus an RS-485 transceiver like the ISL83072EIUZA or isolated Ethernet PHY LAN8742A-CZ-TR. The 1.5 kV isolation prevents ground-potential differences between machines from coupling into the control network. The through-hole 6-pin brick is rugged enough for DIN-rail mounting vibration profiles, and the -40 °C to +85 °C operating range covers unheated cabinet environments. Designers should reserve at least 2 mm clearance around the pins to preserve the rated isolation barrier on the PCB.

Isolated 24 V to 5 V Bus Converter
The MGFS302405-G serves as a compact, isolated point-of-load converter stepping a 24 V industrial bus down to a clean 5 V/6 A rail for downstream point-of-load regulators (e.g. the LT8640EUDC or LMZ14203HTZ). Its 90 % typical efficiency at 24 V input keeps total system losses low enough to avoid active cooling, and the 1.5 kV isolation barrier allows the 5 V domain to float relative to the chassis ground. Compared with discrete non-isolated buck designs, the MGFS302405-G provides factory-tested isolation compliance and reduces BOM count by approximately 15 external components. The wide 9 V to 36 V input also means the same module covers 12 V bus systems without redesign.

Test and Measurement Front-End Power
Bench-top and modular test-and-measurement instruments benefit from the MGFS302405-G's clean isolated 5 V supply for front-end analog signal-conditioning stages. The 1.5 kV isolation shields sensitive ADC inputs (e.g. the LTC2358HLX-18 or MCP3426A0T-E/SN) from ground loops between the instrument chassis and the device under test. The 5 V at 6 A budget supports powering op-amp signal chains (e.g. LTC6226IS6, LT1461AIS8-5) plus the ADC reference and a small FPGA housekeeping block. Its 90 % efficiency at 24 V input allows fan-less operation inside a sealed bench enclosure while still meeting EMC margins in the instrument's CE/UL test report.

ITE Equipment Regulated 5 V Supply
Commercial ITE equipment such as networking switches, point-of-sale terminals, and digital signage controllers use the MGFS302405-G to derive an isolated 5 V supply from an internal 12 V or 24 V intermediate bus. The Cosel MGFS30 family carries the ITE (commercial) application classification, which means the converter is safety-certified for end-product CE/UL/IEC 60950-1 recognition. The 6 A output budget supports powering a small main processor (e.g. LPC18S30FET256, MCIMX6X2CVN08AC) plus peripherals like Ethernet PHYs (KSZ9031RNXIA) and USB isolators (ISO7041FDBQR). The module's 6-pin through-hole package simplifies manufacturing with wave-solder assembly and provides robust mechanical retention during field service.

Isolated Power for Communication Gateways
Industrial communication gateways — protocol converters, IoT edge nodes, and remote telemetry units — use the MGFS302405-G to provide an isolated 5 V rail that powers both a microcontroller and an isolated transceiver. The 1.5 kV isolation between the 24 V field side and the 5 V logic side is mandatory in many IEC 61850 and IEC 61131-2 substation environments, and Cosel's MGFS series is widely accepted for these installations. Pairing the module with the XAIPART-listed ISO7762FDWR digital isolator and an Ethernet PHY (LAN7800-I/VSX) creates a complete isolated communication front end. The wide input range also lets a single PCB variant accept either 12 V battery-backed or 24 V plant power without jumper changes.

Notes de conception
Place a low-ESR 22 µF ceramic or tantalum capacitor within 5 mm of the +Vin/-Vin pins and a 100 µF low-ESR capacitor within 5 mm of +Vout/-Vout. The input capacitor reduces reflected ripple current from the isolated flyback topology, and the output bulk capacitor absorbs load-step transients up to 6 A. Without these capacitors the module may oscillate or show >100 mV output ripple under dynamic load. Estimated: a 100 µF aluminum-polymer cap typically keeps peak-to-peak ripple below 30 mV at 6 A load-step.
The MGFS302405-G is rated for full 30 W output up to approximately 60 °C ambient with no airflow; above 60 °C it must be derated linearly to zero output at 85 °C. Mount the brick vertically with the baseplate flush against the PCB to maximize natural convection cooling through the through-hole leads, which also act as small heatsinks. Estimated: at 50 °C ambient and 24 V input, the module dissipates ~3.3 W (10 % loss) and runs ~25 °C above ambient without forced air.
Maintain at least 2 mm clearance between the input-side pins (+Vin/-Vin) and any output-side copper (including +Vout plane, traces, and chassis ground) to preserve the 1.5 kV DC isolation rating. Do not run digital signals or noisy power traces between the input and output pin clusters; route around the brick to avoid coupling common-mode noise across the isolation barrier. Keep the input and output ground planes physically separated and only joined at the module's -Vin/-Vout pins. The Cosel MGFS series datasheet mechanical drawing provides the certified keep-out zones for reference.
Do not connect the +Vout pin directly to an external adjustable LDO feedback without buffering — the module's output is factory-trimmed to 5 V ±2 % and adding a feedback loop will fight the internal regulation. Do not exceed 36 V input continuously; transients above 40 V can permanently damage the internal MOSFETs. Avoid hot-plugging the input supply at full load — precharge the input capacitor through an inrush limiter (NTC or soft-start circuit) to prevent the input fuse from nuisance-tripping. Estimated: a 5 Ω NTC inrush limiter in series with +Vin typically limits inrush below 5 A at 24 V hot-plug.
Place the module near the edge of the PCB or in a cut-out so the through-hole pins have direct thermal contact with the surrounding air on both sides of the board. Keep high-dV/dt signals (gate drives, switching nodes) away from the brick — the 1.5 kV isolation does not shield against radiated EMI, and common-mode current can inject noise into the regulated output. For best EMC performance, add a small common-mode choke on the +Vin/-Vin lines and a Y-cap (2.2 nF, Y1/Y2 rated) between +Vin and chassis ground before the module input. The Cosel MGFS series EMC compliance report provides reference filter component values.
