Product Introduction
Leyu Electric EDR-75 series is a 75W single-output industrial-grade DIN rail switching power supply, specifically designed for industrial control cabinets, automation equipment, and on-site power supply applications. This series supports TS-35/7.5 or TS-35/15 standard rail mounting, with a body width of only 32.5mm, occupying minimal space and facilitating layout in compact distribution boxes.
The EDR-75 series offers three commonly used output voltage models: 12V/6.3A, 24V/3.2A, and 48V/1.6A, with rated powers of 75.6W, 76.8W, and 76.8W respectively. The product features a wide-range AC input from 85VAC to 264VAC, while also supporting DC input from 120VDC to 370VDC, making it adaptable to various global power grid environments.
This power supply integrates fourfold protection: short circuit, overload, overvoltage, and overtemperature. In overload conditions, it adopts constant current limiting mode, with automatic recovery after fault removal. It uses natural convection cooling with a fanless design, ensuring no noise and higher reliability. The EDR-75 series has a fixed switching frequency of 67KHz. Each unit undergoes 100% full-load burn-in testing before leaving the factory and comes with a 2-year warranty, making it a cost-effective choice for industrial on-site power supply.
Product Features
Standard DIN Rail Mounting: Compatible with TS-35/7.5 and TS-35/15 rails. Snap-fit fixing for easy installation and removal.
Ultra-Slim Body: Only 32.5mm wide, effectively saving space inside control cabinets.
Universal AC Input: 85~264VAC, 47~63Hz, compatible with DC input (120~370VDC), suitable for global use.
Fourfold Protection: Short circuit, overload (constant current limiting, auto recovery), over voltage (shut down output, requires power cycle to recover), over temperature (shut down output, auto recovery after temperature drops).
Free Air Convection Cooling: Fanless design, no noise, no moving parts, especially suitable for long-term continuous operation.
LED Power Indicator: Power status visible at a glance, convenient for on-site troubleshooting.
100% Full Load Burn-in Test: Ensures reliability and consistency of every unit.
High Withstand Voltage Isolation: Input to output 3KVAC, input to FG 1.5KVAC, meeting industrial safety standards.
2-Year Warranty: Leyu Electric provides a 2-year quality warranty for worry-free use.
Product Advantages
1. Industrial-Grade Reliability The EDR-75 series has passed rigorous EMC testing, complying with EN55011, EN55022, EN61000-6-2 and other industrial immunity standards. It operates stably in industrial environments with vibration and electromagnetic interference. Overload protection uses constant current limiting mode rather than hiccup or shutdown mode, making it more friendly for impact loads such as motors and solenoid valves.
2. Economical and Cost-Effective While meeting the basic requirements of industrial applications, the EDR-75 series controls cost through mature circuit topology and manufacturing processes. It offers significant price advantages over high-end DIN rail power supplies of the same power level, making it suitable for high-volume OEM applications.
3. Wide Operating Temperature Range Can operate at full load in ambient temperatures from -10°C to +60°C, adapting to most industrial plants, outdoor cabinets (with protective enclosure), and other scenarios. Storage temperature range from -20°C to +85°C meets transportation and warehousing requirements.
4. Flexible Installation, Space Saving The ultra-slim width of 32.5mm, combined with DIN rail mounting, allows more electrical modules to be arranged on the same rail, especially suitable for space-compact small control boxes or internal equipment integration.
5. Global Input Compatibility Wide input voltage range with no need for a selector switch. Export equipment or cross-border projects can use a unified model, reducing inventory and after-sales complexity. Also supports DC input for battery backup or DC microgrid scenarios.
Application Fields
The EDR-75 series 75W DIN rail power supply is suitable for the following typical applications:
Small PLC Control Systems: Power supply for small PLCs and expansion modules from brands such as Siemens, Mitsubishi, Omron, etc.
Automation Equipment Control Cabinets: Auxiliary power supply inside packaging machines, labeling machines, small conveyor lines, etc.
Sensor and Actuator Power Supply: Provides 24V or 12V power for proximity switches, photoelectric sensors, small relays, solenoid valves, etc.
Building Automation: Access control systems, security cameras, intelligent lighting control boxes, etc.
Instrumentation: Power supply for field display instruments, transmitters, data acquisition modules.
New Energy and Energy Storage Support: DC input characteristic allows connection to battery banks for off-grid or backup power scenarios.
Communication Equipment: Small switches, routers, wireless data transceivers, etc.
FAQ
Q1: Which type of DIN rail is the EDR-75 series suitable for? A: It is suitable for TS-35/7.5 (7.5mm height) and TS-35/15 (15mm height) standard DIN rails. To install, hook the clip on the back of the power supply onto the top edge of the rail, then press the lower part firmly so that the spring clip engages the bottom edge of the rail. To remove, use a flat-blade screwdriver to pry the bottom clip downward.
Q2: What is the input voltage range? Can it be used with 110VAC and 220VAC? A: The input voltage range is 85~264VAC, auto-sensing, no manual switching required. It works stably with 110VAC (e.g., USA, Japan) and 220VAC (e.g., China, Europe) grids. It also supports 120~370VDC DC input. For DC input, connect positive to AC/L and negative to AC/N.
Q3: How does the power supply recover after overload protection? A: The EDR-75 series overload protection uses constant current limiting. When the load exceeds 105%~150% of rated power, the output current is limited to the maximum value and the output voltage drops. Once the load returns to normal, the output voltage automatically recovers without needing to power cycle.
Q4: Does the power supply need derating in high-temperature environments? A: The product can operate at full load in ambient temperatures from -10°C to +60°C without derating. However, ensure adequate ventilation around the power supply (at least 5 cm on all sides) and avoid installation in a sealed, non-ventilated small enclosure. If the ambient temperature exceeds 60°C, use is not recommended.
Q5: Is the output voltage adjustable? What is the adjustment range? A: Yes. For EDR-75-12, the output voltage adjustment range is 12~14V; for EDR-75-24, 24~28V; for EDR-75-48, 48~53V. Adjust via the potentiometer on the front panel (usually with a cross-head adjustment port). Turn clockwise to increase, counterclockwise to decrease. Use a small screwdriver to adjust slowly and monitor the output voltage with a multimeter.
Q6: What is the ripple and noise? Will it affect precision equipment? A: The full-load ripple and noise for the 12V model is ≤100mVp-p, for the 24V model ≤120mVp-p, and for the 48V model ≤150mVp-p (measured under 20MHz bandwidth). These values meet industrial control equipment power supply standards and can normally power PLCs, touchscreens, sensors, etc. If used for analog circuits extremely sensitive to noise, it is recommended to add an LC filter at the output.
Q7: Does the power supply support parallel connection to increase power? A: Direct parallel connection is not recommended. The EDR-75 series does not have current sharing functionality. Paralleling multiple units will cause uneven load distribution, possibly leading to overload or abnormal operation of one unit. For higher power, please select the EDR-120 or EDR-150 series. For redundant backup, use a dedicated redundancy module.
Q8: What is the warranty period? How to contact after-sales service? A: Leyu Electric provides a 2-year quality warranty from the date of manufacture for the EDR-75 series. If a fault occurs under normal use, please contact the purchase channel or Leyu Electric after-sales service department. Provide the product serial number and a description of the fault, and after-sales personnel will guide you.
Q9: What is the difference between the EDR-75 series and the NDR series? A: The EDR-75 series is positioned as an economical 75W DIN rail power supply with a body width of 32.5mm and an operating temperature range of -10°C to +60°C. The NDR series (e.g., NDR-120) features higher efficiency, an even slimmer body (32mm width), and an operating temperature range of -20°C to +70°C with higher efficiency (88%~89%). The EDR series is suitable for cost-sensitive applications with relatively mild environments; the NDR series is suitable for more demanding temperature and space requirements.
