Product Description
DR/EDR/NDR/MDR/HDR Series DIN Rail Power Supply
The DR/EDR/NDR/MDR/HDR Series are high-performance DIN rail power supplies designed to convert 220V AC input into reliable 24V or 12V DC output.
These series offer flexible solutions for various industrial applications including control cabinets, automation equipment, and machinery. Each series features compact rail-mountable design, high efficiency, and comprehensive protections including overload, overvoltage, and short circuit protection. Built with rugged metal housing and reliable components, they ensure stable 24/7 operation in demanding industrial environments.
Functional Features
1.Overcurrent Protection
When the output current exceeds 115%～130% of the rated value, the output voltage begins to drop.
2. Overvoltage Protection
When the output current exceeds 130%～140% of the rated voltage, the output voltage is shut off. This function is only available for power supplies above 250W.
3. Short Circuit Protection
When a short circuit occurs at the output terminal, the power supply will enter a protection state.
4. Overload Protection
When the load power exceeds 130%～140% of the rated voltage, the output voltage is shut off.

Product Selection Guide
For any questions, please contact us.
Please purchase the power supply based on existing product or model information.
Note: Actual product may vary slightly from photos due to photographic lighting and display differences.
1.If you do not know the model number, please provide the required output voltage (V), output current (A), or output power (W), along with the input voltage (e.g., 220V, 110V, 380V). Our customer service will recommend the appropriate model.
2. When the power supply is used for inductive loads such as motors or pumps (which require much higher starting power than rated), it is recommended to consult the motor or pump manufacturer to determine the required power supply capacity. For example, a 5A motor may draw 10A or more at startup; a 5A power supply would not be sufficient.
3. Model Number Explanation: The first letters represent the series name, which determines the外形 and features. The middle number indicates the rated power (W). The last number indicates the DC output voltage (V). The rated current can be calculated as Current = Power / Voltage. Example: NDR-240-24 means NDR series, 240W rated power, 24V DC output. The rated current is approximately 240/24 = 10A.
