The Ultimate in High-Power Density, Versatility, and Multi-Industry Reliability
MEAN WELL is expanding its highly successful NSP family. Following the rollout of the 75W to 750W models, the family welcomes its new high-power heavyweight: the NSP-1000 Series.
The NSP-1000 packs a massive 1000W of power into a low-profile, ultra-compact enclosure (just 230 x 127 x 41 mm). Backed by an industry-leading 5-year warranty, it is engineered to be a durable, future-proof cornerstone for global industrial, medical, and commercial infrastructure.
Unmatched Versatility Across Industries
The NSP-1000 is uniquely certified across almost every major sector, eliminating the need to source different power supplies for different markets. It features 2xMOPP medical isolation and an ultra-low leakage current (<350uA), making it perfectly safe for medical BF-rated applications.
Additionally, it is certified for Information Technology (ITE), industrial automation, household appliances, and semiconductor manufacturing (SEMI F47).

Smart Power Management & High Scalability
Designed for complex electrical systems, the NSP-1000 offers advanced control and scaling options:
- 200% Peak Power Capability: Effortlessly handles high startup currents from inductive or capacitive loads.
- Fully Programmable Outputs: Fine-tune your system with an ultra-wide programmable output voltage (0–120%) and adjustable output current (0–100%).
- Parallel Expansion: Scalable up to 4000W (3+1 units in parallel) to handle growing system demands without requiring a redesign.
- Digital Communication: Features a built-in CANBus interface (with optional MODBus support) for real-time remote system monitoring and precision control.
Built for the Harshest Environments
Whether deployed at high altitudes or in extreme temperatures, the NSP-1000 delivers consistent performance. It features a conformal-coated PCB to protect against dust and moisture, operates up to 5,000 meters, and withstands temperatures from -40°C to +85°C.
Despite its high-octane cooling capabilities, the built-in smart fan operates at a low-noise level (<45 dB), making it ideal for noise-sensitive, quiet environments.
