The global ACDC DIN Rail Power Supply market was valued at US$ 694.5 million in 2020 and is anticipated to grow with a CAGR of 5.2% over the forecast period of 2021-2027, according to a report(source: Marketintelligencedata). ACDC DIN Rail power supplies can be widely used in a wide range of applications from building automation and industrial control to electric power, railway and medical. In order to be well-adapted to various industries, they need to meet stringent requirements that deliver high efficiency and reliability, save board space, and reduce overall system cost without sacrificing performance. Meanwhile, they need to operate in different environments. Mornsun is proud to introduce its top 4 cost-effective, compact AC/DC DIN Rail power supplies of rail power solutions to address these challenges.

120-480W Ultra-slim LIFxx-10BxxR2 Series with PFC

Mornsun Power introduced a low profile ACDC DIN Rail power supply with PFC rated from 120W to 480W. This series has ultra-slim compact structure with thickness of 41/48mm that enable designers to reduce their power solution volume by as much as 40% compared with competing product. Such compact size (41x124x110mm for 120W/240W, 131.5*48*125mm for 480W) make them stand out of the market and far ahead of the mainstream. They are very flexible and convenient to use in cabinets and chassis mounts, easy to install, disassemble, and replace.

LIFxx-10BxxR2 series also offers universal input voltage 85-264VAC/120-370VDC, accepts AC or DC dual-use, and meets harmonic current standards (IEC/EN61000-3-2 CLASS A) to protect the system against malfunction and help achieve better voltage quality and less power loss. The product’s surface is protected by nickel plating to prevent rust and moisture, thus making it more durable. Its high efficiency up to 94% coupled with the extended -40°C to +70°C operating temperature range delivers more power and high reliability in harsh conditions. In addition, the device’s strong transient capability at 150% over power and short-circuit current up to 200% maximum allows for smooth turn on performance. Offering both safety and durability, all series hold complete certifications and provide competitive technology.

75W Cost-effective LI75-20BxxR2S Series
Another highly cost-effective compact DIN Rail power supply LI75-20BxxR2S series without PFC function was also designed to meet designers’ needs for size, performance and cost in applications.This series’ thickness is 6% slimmer than the nearest competitive module with a lower profile, measuring 32x125x87.5 mm. Target applications include industrial control, LED, street light control, electric power, security, communication and other scenes with limited space.

In addition, LI75-20BxxR2S series also delivers wide operating temperature range of -40°C to +70°C, good EMC performance with conducted emission and radiated emission meeting CISPR32/EN55032 CLASS B, harmonic current meeting IEC/EN61000-3-2 CLASS A along with multiple protections such as output short circuit, over-voltage, over-temperature, and constant-current protections, which makes it highly reliable in some extreme conditions.

Other exceptional features include an universal input voltage range of 90-264VAC, 105%-150% constant current protection, and peak efficiency up to 90% for 48V/1.6A output.

Backed by Mornsun’s advanced technology, optimized process with maximum automated manufacturing, it helps save labor and maintenance costs for the designers as well.

15-150W LIxx-20BxxPR2 Series

The stepped shape plastic LIxx-20BxxPR2 series covers output power of 15W, 30W, 60W, 100W, 150W and offers output voltages of 5V, 12V, 24V and 48V. This series saves space with thickness of only 58mm, which make it easy to install in the narrow space.

Thanks to its ripple & noise of 39mV that is twice times lower than the competing products, it has the better reliability to enable the system to avoid the risk of data loss and running errors. Another advantage lie in its extended temperature range of -40℃ to +70℃ with derating to 85% load when the input voltage is 85VAC. The system is able to start up normally even in the cold winter while the outdoor temperature going lower to -40℃. Other capability such as great EMI performance meeting CISPR32/EN55032 CLASS B without external components, no bending feet and lying wire required for the design that not only makes them reliable but saves costs as well.

The LIxx-20BxxPR2 series also comes with high efficiency up to 91.5%. Other key features include input voltage range of 85-264VAC (277VAC available) or 120-370VDC (390VDC available), meeting over-voltage class III, the ability that withstands 300VAC surge input for 5s, which helps improve reliability in electronics that operate in harsh environments.

120W LI120-20BxxR2S Series

With a dimension of 36x125x100mm and weight of 410g, the LI120-20BxxR2S series is smaller and lighter solution with 10% smaller in the thickness than the competing product that help improve the space utilization for designers. Compared with the complex heat dissipation design in the market, this series optimizes the duct design and utilizes the shell for better heat dissipation. In addition, less heat sinks required in this device is also help to reduce cost for the power design.

Operating an input voltage range of 90-264VAC/127-373VDC, the LI120-20BxxR2S series supports the output voltage of 12V, 24V and 48V. It also supports wide range operating ambient temperature range of -20℃ to +60℃, High isolation voltage of 4000VAC and multiple protections such as output short circuit, over-current, over-voltage, over-temperature protection. It enables 3 seconds start-up in low temperature, and provides low-voltage bus power for industrial control, new energy, petrochemical, metallurgy, railroads, DC charging stations and other internal rail-mounted control cabinet systems.
