Hikvision 75W Industrial NDR-75-48 DIN Rail Power Supply with 48VDC Output, Overload Protection, Short Circuit Protection

Product SKU: Hikvision NDR-75-48

Product Overview

The Hikvision NDR-75-48 75W Industrial DIN Rail Power Supply is designed to provide stable 48VDC power for compatible industrial, transmission and security system equipment. It features 75W output capacity, DIN rail mounting, overload protection and short circuit protection, making it suitable for compact control cabinets, network transmission equipment, industrial power distribution and professional security installations. The DIN rail form factor supports neat cabinet integration where reliable power is required for compatible low-to-medium power devices. This model is best selected where a compact 48VDC industrial power supply is required for a structured installation environment.

Key Capabilities

Best For

• Compact Industrial Cabinets: Suitable for DIN rail installations where 48VDC power is required in a smaller power capacity.
• Transmission Equipment: Practical for compatible network and security transmission accessories requiring stable DC output.
• Security System Infrastructure: Useful for professional CCTV, access control or communication equipment cabinets where compatible 48VDC power is needed.
• Control Panel Installations: A good option where power supplies need to be mounted cleanly on standard DIN rail.
• Lower-Power 48VDC Loads: Best where a compatible installation requires 75W power capacity rather than a larger industrial supply.

Why Choose the NDR-75-48

The NDR-75-48 is a practical choice when a professional installation needs reliable 48VDC power in a compact DIN rail format. Its 75W output capacity makes it suitable for compatible low-to-medium power equipment, while overload and short circuit protection support safer system operation when correctly installed. The DIN rail design keeps cabinets organised and serviceable, making it useful for structured security, industrial and network transmission projects. For systems supplied through Security Wholesalers, this power supply should be selected after confirming total device load, voltage requirements, cabinet space, ventilation, wiring method, protection requirements and installation environment.

Ideal Use Cases

Choosing the Right Model

• Choose this model if: You need a 75W industrial DIN rail power supply with 48VDC output, overload protection and short circuit protection.
• Choose a different power supply if: The installation needs a different voltage, higher wattage, lower wattage, outdoor-rated enclosure, plug-pack power adapter, PoE injector, UPS battery backup or device-specific power supply.
• Check before ordering: Confirm total wattage load, required voltage, wiring method, cabinet space, DIN rail compatibility, ventilation, circuit protection, installation environment and compliance requirements.

FAQs

1. What is the Hikvision NDR-75-48 used for?
   The NDR-75-48 is used as an industrial DIN rail power supply for compatible equipment requiring 48VDC power. It is suitable for security, transmission, network and industrial cabinet installations where a stable compact DC power source is required.
2. How much power does the NDR-75-48 provide?
   The NDR-75-48 provides 75W output capacity. Before installation, the total connected load should be calculated to ensure it remains within the available power rating with an appropriate safety margin.
3. What output voltage does this power supply provide?
   This model provides 48VDC output. Connected equipment must be compatible with 48VDC operation before the power supply is installed or connected.
4. What does DIN rail mounting mean?
   DIN rail mounting means the power supply is designed to clip onto a standard DIN rail inside a suitable cabinet or control panel. This helps keep professional installations organised, serviceable and easier to integrate with other cabinet-mounted equipment.
5. Does this power supply include overload protection?
   Yes. The NDR-75-48 supports overload protection, helping protect the power supply and connected installation when excessive load conditions occur.
6. Does it include short circuit protection?
   Yes. Short circuit protection is supported, helping reduce risk during fault conditions. For systems supplied through Security Wholesalers, correct wiring, circuit protection and qualified installation should still be followed.
7. When should I choose this instead of a larger DIN rail power supply?
   Choose the NDR-75-48 when the connected equipment only needs a lower 75W capacity. If the total load is higher or future expansion is expected, a larger compatible 48VDC DIN rail supply may be more suitable.
8. What should be checked before installation?
   Before installation, confirm the required voltage, total device load, cable size, DIN rail space, cabinet ventilation, circuit protection, grounding, environmental conditions, access for servicing and whether the installation must be completed by a qualified electrician or licensed technician.
