![[Power Supply Design Proposal Example] Ultra-wide range support for input DC 24V to 110V.](https://image.mono.ipros.com/public/product/image/d76/2000739413/IPROS95578210802661058190.png?w=280&h=280)
By eliminating the switch, it is possible to achieve stable output! Reliability has also improved!
We received a request from a customer to develop a power supply with an ultra-wide input voltage range of 12 to 110V. Typically, when the range is wide, it is necessary to separate the power supply by input voltage, such as 12 to 24V or 48 to 72V, or to use a switch to toggle between them. By using a buck-boost switching converter that can automatically switch between boost and buck operations, we can accommodate an ultra-wide input range of DC 24V to 110V. Eliminating the switch allows for stable output and improves reliability. [Challenges] ■ Development of a power supply with an ultra-wide input voltage range of 12 to 110V ■ When the range is wide - It is necessary to separate the power supply by input voltage, such as 12 to 24V or 48 to 72V - Or it is necessary to use a switch to toggle between them *For more details, please refer to the related link page or feel free to contact us.

Adopted synchronous rectifier circuit for output! Achieved high efficiency within the size of 60×250×150!
We received a request to fit a power supply with an output of 24V 10A and an input of AC 100-200V wide range, including peripheral circuits such as output signal control, into a size of 60×250×150. Typically, in natural air cooling, the power supply is calculated at 8.5cc per watt, and if a standard circuit design is used, it will not fit within the requested size. Therefore, our company has achieved high efficiency by adopting a synchronous rectification circuit at the output to enhance the conversion efficiency of the switching regulator, fitting it into the size of 60×250×150. [Challenges] ■ Power supply with output of 24V 10A and input of AC 100-200V wide range - We want to fit it into a size of 60×250×150, including peripheral circuits such as output signal control. *For more details, please refer to the related link page or feel free to contact us.

Achieving an accuracy of ±0.5% of the actual value! We respond to high precision demands in constant current output.
This is an example of a DC current amplifier for large coils developed and designed by our company. There was a request for a constant current output accuracy of ±1% or less relative to the input voltage. Therefore, we selected high-precision devices for the isolation amplifier used in the control section. By using devices that can achieve an accuracy of 1/100 compared to general-purpose resistors and capacitors, we optimized the circuit design around the isolation amplifier. Additionally, there was a request to minimize the use of magnetic components, so we used materials like aluminum and brass. 【Product Overview (Partial)】 ■ Name: Constant Current Power Supply ■ Application: Constant current power supply for large coils ■ Input Voltage Range: AC 93V to 115V 3φ ■ Output Specifications: 0 to 25V, 5A ■ Number of Channels: 1 channel *For more details, please refer to the related links or feel free to contact us.
Achieving 24V/10A or 48V/5A output! Introducing examples of DC stabilized power supplies for controller devices.
We received a request for two types of power supplies with output voltages of 24V and 48V, under the conditions of the same shape, the same input voltage range, and the same output power. Therefore, we implemented two output circuits of 24V/5A and achieved 24V/10A or 48V/5A output by switching between parallel and series operation through internal wiring changes. Furthermore, the circuits can be shared, allowing for a reduction in development time and initial costs. 【Case Overview (Partial)】 ■ Name: DC Stabilized Power Supply for Controller Devices for Power Plants ■ Application: DC Power Supply ■ Input Voltage Range: AC85–132V, DC80–163V ■ Output Specifications: 24V/10A or 48V/5A ■ Number of Channels: 1 Channel *For more details, please refer to the PDF document or feel free to contact us.
