The 41GA5E Series is a new compact AC/DC converter range available from Ideal Power.
Manufactured by Yuan Dean, the series delivers 1W to 5W from a fully encapsulated 1″ × 1″ PCB-mounted package. It supports a wide input range, offers output options from 3.3V to 48V DC and provides 3kV AC input-to-output isolation.
For engineers working with limited PCB space, the range offers a practical way to add AC/DC conversion without taking up more room than necessary.
Meet the 41GA5E Series
The 41GA5E Series brings several output, voltage and wattage options together in one compact converter family.
Key features include:
- 1W to 5W output options
- 90 to 264V AC universal input
- 120 to 370V DC input capability
- 3.3V to 48V DC output options
- Efficiency up to 85%
- 3kV AC input/output isolation
- Fully encapsulated 1″ × 1″ package
- Short-circuit, overload and overvoltage protection
- UL/cUL/IEC/EN 62368-1 approvals
- EN 55032 Class B EMI compliance
- 3-year warranty
With several combinations available, design teams can stay within the same converter family across different low-wattage requirements.
Universal 90 to 264V AC input
If your equipment will be used across different regions, the input range needs to cope with different mains supplies.
The 41GA5E Series supports 90 to 264V AC, covering the mains voltages commonly used around the globe.
It can accept 120 to 370V DC too, giving you another option for equipment that runs from a high-voltage DC source.
Compact 1″ × 1″ encapsulated package
PCB space can become tight once control, communication and interface circuitry are added.
The 41GA5E Series measures 25.4 × 25.4 × 16.1mm and comes in a fully encapsulated plastic case. Its compact footprint helps keep the AC/DC section contained within a small area of the board, leaving more space for the rest of your design.
Output options from 3.3V to 48V DC
The range is available with:
- 3.3V DC
- 5V DC
- 9V DC
- 12V DC
- 15V DC
- 24V DC
- 48V DC
Output ratings run from 1W to 5W, depending on the model you choose.
Having several output voltages and wattages within one family can make product selection simpler, especially if you are developing related products with different electrical requirements.
Efficiency up to 85%
Selected models reach up to 85% efficiency.
Lower conversion losses can help reduce heat inside compact assemblies, which can make thermal management easier where airflow or board space is limited.
The series uses free-air convection cooling, so it does not rely on a dedicated fan under its stated operating conditions.
3kV AC input/output isolation
The 41GA5E Series provides 3kV AC input-to-output isolation, helping maintain electrical separation between the mains input and the low-voltage output circuitry.
Isolation resistance is rated at 100MΩ minimum at 500V DC.
For designs where electrical separation forms part of the safety requirements, these specifications give engineers a clear starting point during component selection.
Built-in protection
The 41GA5E Series includes:
- Short-circuit protection
- Overload protection
- Overvoltage protection
Short-circuit and overload protection recover automatically once the fault condition clears.
These protection functions help the converter respond safely to abnormal conditions and can be considered alongside the wider protection requirements of the finished equipment.
Operating temperature from -25°C to +70°C
The 41GA5E Series operates from -25°C to +70°C, subject to the stated derating curve.
Full output is available across the lower part of the temperature range, with output derating required as the ambient temperature rises.
For storage, the series is rated from -40°C to +85°C.
Safety and EMC approvals
The series holds UL, cUL, IEC and EN 62368-1 approvals, supporting recognised safety requirements for electronic equipment.
For EMC performance, it meets EN 55032 Class B requirements for conducted and radiated emissions, with immunity covered under the relevant EN 61000 standards.
The series comes with a 3-year warranty for added peace of mind.
Where can the 41GA5E Series be used?
Its small PCB footprint, wide input range and choice of DC outputs make the 41GA5E Series suitable for a range of low-wattage electronic equipment.
Typical applications include:
- Industrial controllers
- IoT gateways
- Fire alarm control panels
- Security systems
- Embedded control boards
- Electronic instruments
- Communication devices
Across these applications, a compact AC/DC converter can make component placement easier, help simplify board design and support consistent operation across different input conditions.
