As connected home and broadband devices continue to operate in always-on (24/7) environments, power supply reliability plays a critical role in maintaining stable performance. The NBS36W from NetBit Electronics is a wall-mount AC/DC power supply developed specifically for Customer Premises Equipment (CPE) applications and high-volume deployments, based on a high-efficiency switch-mode power supply architecture optimized for electrolytic-capacitor-free operation and extended service lifetime.
Addressing Traditional Power Supply Limitations
Conventional power supplies commonly rely on electrolytic capacitors, which can limit operational lifespan and introduce risks associated with ageing components. The NBS36W addresses these challenges through E-capless architecture that fully eliminates electrolytic capacitors.
This design removes key lifespan constraints while supporting long-term operational stability in connected device environments.
E-Capless Architecture for Long Operational Life
The NBS36W is described as the world’s first CPE power supply to fully eliminate electrolytic capacitors, enabling best-in-class reliability and designed to support an operational lifetime exceeding 10 years under typical operating conditions.
The power supply instead uses an innovative topology which can operate using solely
- Metallized polypropylene (MPP) film capacitors
- Polymer solid aluminium capacitors
- Multilayer ceramic capacitors (MLCC)
This approach eliminates failure mechanisms associated with liquid electrolyte leakage and reduces the risk of long-term PCB corrosion.
Stable Operation for Always-Connected Devices
The design focuses on delivering consistent electrical performance across continuous operating environments:
- Reduced inrush current, minimizing stress on internal components
- Improved system stability
- Power factor greater than 0.9 to support efficient energy usage
- Performance aligned with legacy CPE adapters without downgrade
These characteristics support reliable operation across broadband and connected home deployments.
Engineered for CPE Applications
The NBS36W is suitable for a wide range of operator and consumer equipment, including:
- Set-top boxes and PVRs
- DSL, DOCSIS and G-PON gateways
- Wi-Fi extenders
- Home automation systems
- Smart metering devices
Compliance and Eco-Design Alignment
The power supply meets recognised safety, efficiency and environmental standards, including IEC 62368-1 safety certification, ErP Lot 7 efficiency requirements, and RoHS/REACH compliance. Eco-design options include PCR materials alongside lead-free, phosphorus-free and halogen-free configurations.
Flexible Deployment Options
The NBS36W platform can be customised to meet specific application requirements, including configurable output parameters and custom labelling or branding options.
With its E-capless architecture and CPE-focused design, the NBS36W provides a reliable power platform engineered for modern connected device deployments.
