Product Introduction
In factory automation, control cabinet integration, and various industrial sites, the stability and ease of installation of the power supply module often determine the operating efficiency of the entire system. Based on years of power supply manufacturing experience, Leyu Electric introduces the DR‑60 series DIN rail switching power supply.
Designed specifically for industrial control environments, this series has a body width of only 78mm and can be directly snapped onto TS‑35/7.5 or TS‑15 standard DIN rails without additional mounting brackets, significantly saving space inside control cabinets. It currently offers four mainstream output voltages: 5V / 12V / 15V / 24V. Among them, the 24V model (DR‑60‑24) delivers 60W of power and 2.5A current, sufficient to drive common loads such as small PLCs, relays, and sensors.
The DR‑60 features a 88–264VAC wide voltage input, adapting to power grid conditions in different regions worldwide (single‑phase 110V or 220V) while maintaining stable output during voltage fluctuations. The entire series has passed safety certifications such as UL60950‑1 and TUV EN60950‑1, and meets EN55022 Class B electromagnetic compatibility requirements, making it suitable for heavy industrial environments.
Product Features
True “plug‑and‑play” installation
The rail clip uses a metal spring structure, allowing removal and fixing without tools, saving 60% installation time compared to screw‑fixed power supplies.
Full‑range AC input No switch needed – automatically adapts to 88–264VAC or 124–370VDC, suitable for both 110V and 220V power scenarios, reducing inventory models.
Multiple electrical protections
Short circuit protection: current limiting, auto‑recovery after fault removal
Overload protection: enters constant current mode at 105%–160% rated power
Over voltage protection: output shut down, requires power‑on reset All protection actions will not damage the power supply itself.
Free air convection cooling No built‑fan, relies on natural heat exchange between housing and air – zero noise, no dust accumulation risk, ideal for clean rooms or quiet environments.
100% full load burn‑in test Every DR‑60 undergoes a 2‑hour full load burn‑in at 60℃ before leaving the factory, eliminating early failure risks.
2‑year free warranty Covers material and process defects – direct replacement for non‑human damage.

FAQ
Q1: What is the actual output power of the DR‑60‑24? Can it be overloaded? A: Rated power is 60W. Short‑term (<3 seconds) peak load up to 90W is allowed (overload protection point approx. 105%–160%). Long‑term overload is not recommended as it may trigger over‑temperature protection or shorten lifespan.
Q2: What should I pay attention to when installing on a DIN rail? A: First hook the upper clip onto the top edge of the rail, then press downward to snap the lower spring clip onto the rail. To remove, use a screwdriver to pry the spring clip downward. Ensure the rail is properly grounded (if system requires).
Q3: Why is the input voltage range specified as 88–264VAC instead of 100–240VAC? A: The Leyu DR‑60 has a larger design margin, maintaining stable operation even when rural grid voltage drops to 88V or industrial voltage rises to 264V, offering better compatibility than industry standards.
Q4: Can the output voltage be adjusted via a potentiometer? A: Yes. The 24V model has an adjustment range of 21.6–26.4V, used to compensate for long cable voltage drops or to drive devices that require higher voltage (e.g., 24V solenoid valves sometimes operate more reliably at 26V).
Q5: Operating temperature is -20℃ to +60℃. Does derating start at +50℃? A: No derating needed at +50℃. Linear derating to 80% load occurs from +50℃ to +60℃. Refer to the “derating curve” on the product label for actual use.
Q6: Are CE and UL certifications for the whole unit or just components? A: Whole unit certification. The DR‑60 series has passed TUV lab EN60950‑1 testing and UL 60950‑1 certification (documents available from Leyu sales).
Q7: How to handle a failure during the warranty period? A: Contact Leyu after‑sales support with proof of purchase. After inspection confirming a product quality issue, a free replacement of the same or upgraded model will be provided within 2 years.

First, a few wordsEver had a battery‑powered device die because the voltage dipped? Or a solar panel array underperform because the DC level just wouldn’t match what comes after?That’s where a DC‑DC converter steps in. It’s not glamorous, but it’s inside almost every system that runs on DC – EV auxi
Choosing between a 12V and a 24V system often feels like a technical crossroads. If you are designing a control panel or upgrading an automated line, this decision dictates which components you can buy and how much heat your cabinet will generate.
Selecting the right power source for your Programmable Logic Controller (PLC) cabinet is more than a technical checklist; it is the heartbeat of your industrial automation.
Choosing the right power solution determines whether your industrial automation system runs smoothly or faces constant downtime. If you have ever looked inside a modern control cabinet, you likely saw a metal strip holding various modular components.
In the fast-paced world of modern manufacturing, reliability isn't just a goal; it is a requirement. At the heart of almost every automated control cabinet, you will find a critical component: the DIN Rail Power Supply.
Installing a DIN Rail Power Supply might seem like a straightforward task for a seasoned electrician, but it requires precision and a deep understanding of safety protocols.
