The MDR-10 is a low-power switching power supply series from Leyu Electric, designed specifically for DIN rail mounting. This series offers four standard voltage output models: MDR-10-5 (5V/2A), MDR-10-12 (12V/0.84A), MDR-10-15 (15V/0.67A), and MDR-10-24 (24V/0.42A), all with a rated power of 10W. The product dimensions are only 22.5mm (W) × 90mm (H) × 100mm (D), and it weighs approximately 0.17kg, making it very space-saving in control cabinets. Leyu Electric offers a two-year warranty on this power supply, reflecting confidence in its quality.
The MDR-10 series complies with multiple safety and electromagnetic compatibility standards (designed with reference to UL508, TUV EN60950-1, EN55011, etc.) and can be used as a component installed in end equipment.

Based on the official datasheet, the MDR-10 series features the following prominent characteristics:
Ultra-thin DIN rail mounting: 22.5mm slim design, standard 35mm DIN rail snap-fit, suitable for space-constrained distribution boxes or control enclosures.
Universal input voltage: Supports wide input of 85~264VAC or 120~370VDC, compatible with 47~63Hz mains frequency, adapting to power grids in different countries and regions.
High conversion efficiency: Depending on the model, efficiency reaches 77%~84% (at 230VAC input, rated load), effectively reducing heat generation.
Comprehensive protection mechanisms:
Overload protection: When output power exceeds 105% of rated, enters hiccup mode, automatically recovers after fault removal.
Over-voltage protection: Each model has its own protection trigger point (e.g., 5.75-6.75V for 5V model, 27.6-32.4V for 24V model). When triggered, output shuts down and requires re-power-on to recover.
Low leakage current: Less than 1mA/240VAC, improving system safety.
Strong environmental tolerance:
Operating temperature range: -20℃~+70℃, humidity 20%~90% RH (non-condensing).
Storage temperature: -40℃~+85℃.
Vibration resistance: 10~500Hz, 2G acceleration, 60 minutes along each X, Y, Z axis.
Electrical isolation performance: Input-output withstand voltage 3KVAC, input-FG 2KVAC, output-FG 0.5KVAC; insulation resistance ≥100MΩ (at 500VDC).
Compared to other 10W DIN rail power supplies, the advantages of the MDR-10 series are mainly reflected in:
Fine specifications, precise load matching
Four voltages (5V, 12V, 15V, 24V) are available, allowing users to select the voltage closest to their downstream equipment’s needs, avoiding power waste or voltage conversion losses. For example, the 12V model has a rated current of 0.84A, just right for driving small relays or LED indicators.
Low ripple & noise, stable output
Under 20MHz bandwidth, ripple & noise is controlled between 80mVp-p (5V) and 150mVp-p (24V), friendly to sensitive analog circuits or communication devices. Voltage tolerance (including set-up tolerance, line regulation, and load regulation) is controlled between ±1% and ±5%, with the 24V model achieving the best ±1%.
Ample start-up and hold-up time
At full load, start-up time is 500ms and rise time 30ms under 230VAC; under 115VAC, start-up time is 1000ms. Hold-up time is 25ms (115VAC) to 120ms (230VAC), helping to cope with brief power interruptions.
Complete safety certifications
Although marked as “designed with reference to” multiple international standards, it indicates that the product development phase has fully considered UL, TUV, EMC requirements, facilitating the end equipment’s certification process.
Packaging and cost advantage
72 pieces per carton, total weight 13.2kg, volume 0.91 cubic feet, suitable for bulk purchasing and warehousing.
Industrial control systems: Provide 24V or 12V power to PLCs, sensors, small relays, solenoid valves, etc.
Building automation: Power smart lighting modules, intercom systems, security cameras, access controllers, etc.
Machine internal auxiliary power: As a control board power supply unit in CNC machines, packaging machinery, textile machinery.
Instrumentation: Provide 5V for logic circuits, 15V for op-amp circuits, or 12V for display modules.
Renewable energy support: Such as control power for photovoltaic combiner boxes, wind turbine pitch systems (utilizing its wide input voltage feature).
Q1: Can the MDR-10 series operate continuously at full load in a 70℃ environment?
A: The datasheet specifies an operating temperature range of -20℃~+70℃, but does not provide a derating curve. It is recommended to reduce the load appropriately under high-temperature conditions or ensure adequate ventilation and heat dissipation in the control cabinet. If the ambient temperature exceeds 50℃, it is advisable to consult Leyu Electric’s technical support.
Q2: How to recover after over-voltage protection is triggered?
A: When over-voltage protection is triggered, the output is latched off. You need to completely disconnect the input power (unplug the plug or turn off the circuit breaker), wait a few seconds, and then reapply power. The output will then return to normal.
Q3: Can this power supply be paralleled to increase output power?
A: The official datasheet does not mention paralleling functionality. The MDR-10 series does not have active current sharing design and is not recommended for direct paralleling. For higher power requirements, please use the Leyu MDR-20 or MDR-60 series.
Q4: Can capacitive loads be connected to the output, such as LED strips?
A: Yes, but note that the inrush current from capacitive loads may trigger overload protection. It is recommended that the total load capacitance not exceed 2000μF (for 24V output) or be scaled accordingly. If a large capacitor is required, a current limiting resistor can be added in series, or a higher power model can be used.
Q5: Under what conditions is the ripple & noise specification “120mVp-p” measured?
A: According to the datasheet, measurements are taken at 230VAC input, rated load, 25℃ ambient, using a 20MHz bandwidth oscilloscope, with a 12-inch twisted pair terminated by a 0.1μF and 47μF parallel capacitor. In actual applications, ripple may increase slightly if the wiring distance is long.
Q6: Does this product have CE certification?
A: The datasheet states “designed with reference to” EN series standards, but does not explicitly list certification marks. It is recommended to confirm the certification status of specific batches with Leyu Electric at the time of purchase. However, the product design strictly follows relevant EMC and LVD requirements, suitable for light industrial levels.
Q7: What is the no-load power consumption?
A: The datasheet does not directly provide no-load power consumption data. Reference measured value: under 230VAC input, no-load power consumption is approximately 0.3~0.5W (subject to actual conditions). If very low standby power consumption is required, consider adding an external switch to the design.
