Explore our flagship OEM/ODM power supply units engineered for industrial automation, CCTV systems, telecom infrastructures, and high-reliability LED lighting environments.
In modern commercial, industrial, and architectural lighting, the LED driver is the vital link between an unpredictable electrical grid and sensitive solid-state diodes. Selecting off-the-shelf power supplies often results in early harmonic distortion failure, thermal runaway, flickers under voltage dips, and premature system breakdown.
As a specialized OEM/ODM manufacturer backed by 30+ years of power electronics innovation (Sanstar Microsystems / Micro Power), we engineer custom LED drivers with advanced Active Power Factor Correction (PFC > 0.98), Low Total Harmonic Distortion (THD < 10%), and galvanic isolation. Our tailored designs guarantee zero acoustic noise, flicker-free dimming, and long operating life under harsh environments.
Procurement teams facing high-volume global deployments must balance unit cost against warranty liability. Generic commodity supplies frequently compromise on electrolytic capacitor grade, EMI filtering, and surge protection levels.
| Engineering Parameter | Standard Off-The-Shelf Drivers | Custom Micro Power OEM/ODM LED Drivers | Strategic Benefit for OEMs |
|---|---|---|---|
| Input Voltage Tolerance | 180V – 240V AC (Narrow) | 90V – 290V AC Wide Input | Immuity to severe grid dips, brownouts, and rural voltage spikes. |
| Power Factor (PFC) & THD | PFC > 0.90, THD < 20% | PFC > 0.98, THD < 8% | Complies with global energy codes (DLC 5.1, ErP) & reduces line losses. |
| Surge Protection Level | 1kV – 2kV Differential Mode | 6kV – 10kV / 20kV Combined Mode | Drastically reduces field returns in outdoor streetlights and high bays. |
| Thermal Dissipation | Air Convection / Plastic Housing | Aluminum Enclosure + Thermally Conductive Potting | Maintains component temperatures below 65°C at 50°C ambient. |
| Dimming & Control Protocols | Single Protocol (0-10V or Triac) | Multi-Protocol (DALI-2, D4i, 0-10V, PWM, Matter, Zigbee) | Seamless integration into smart building management platforms. |
| Quality Assurance & Testing | Batch Sampling Inspection | 100% Full-Load Automated Burn-in & High-Voltage Test | Guarantees zero-defect delivery for OEM assembly lines. |
When selecting a custom OEM LED driver supplier, evaluating MTBF (Mean Time Between Failures) requires scrutinizing the thermal stress on critical components. A 10°C reduction in internal capacitor operating temperature effectively doubles the driver's lifespan. Our R&D team uses finite element thermal modeling to ensure localized hot spots are eliminated before PCB fabrication.
The power supply landscape is undergoing a technological revolution driven by decarbonization, IoT connectivity, and wide-bandgap semiconductor devices.
Gallium Nitride (GaN) and Silicon Carbide (SiC) power switches are replacing traditional Silicon MOSFETs in high-power LED drivers (200W–1000W). GaN technology enables switching frequencies up to 500 kHz, dramatically shrinking magnetics volume and raising efficiency beyond 96%.
Future streetlight and commercial luminaire tenders demand D4i (DALI for IoT) compliance. Modern OEM drivers must not only provide DC power but also supply 24V auxiliary power to sensor nodes and transmit real-time operational data (energy consumption, temperature, diagnostics) to central management systems.
Strict European ErP directives and global sustainability initiatives mandate that LED drivers be easily serviceable and recyclable. OEM buyers are transitioning away from non-repairable epoxy-potted drivers toward modular chassis with replaceable internal power sub-assemblies.
As the specialized power-electronics brand of Sanstar Microsystems Pvt. Ltd. (Nagpur, India), we bring over three decades of field-proven reliability to global OEM customers.
Unlike simple assembly facilities, our engineering team manages the complete design lifecycle: high-frequency transformer design, custom choke winding, PCB layout optimization, and firmware programming for microcontroller-based digital dimming drivers. We quickly adapt voltage, current, and physical footprint to fit your exact luminaire space.
Quality assurance is embedded in our manufacturing infrastructure. Operating out of an anti-static, highly structured production facility in Nagpur, India, every single LED driver and SMPS unit undergoes 100% full-load burn-in testing and high-voltage dielectric isolation testing prior to dispatch.
Navigating global compliance is seamless when partnering with Micro Power. Our product ranges carry recognized certifications including BIS (IS 13252), CE EMC/LVD directives, and UL compliance standards. Test reports and technical construction files (TCF) are provided to support your luminaire approval process.
Our dedicated export and OEM engineering desk works hand-in-hand with procurement managers. We support low-volume prototype qualification runs, provide customized private labeling, and manage scalable mass production runs with predictable lead times.
For standard electrical modifications (such as custom current settings, altered wire harness lengths, or specialized output voltages), our MOQ starts at 500 units. For complete ground-up mechanical enclosure tooling and bespoke PCB layout developments, typical MOQs range between 1,000 to 3,000 units depending on power rating.
We ensure thermal reliability by using high-thermal-conductivity aluminum housings, automated thermally conductive silicone potting, and premium 105°C rated capacitors. Our drivers are engineered with automatic thermal derating mechanisms that reduce output current if ambient temperatures exceed safe thresholds, preventing catastrophic LED failures.
Yes. Designed and built in India (where power grid variations can be severe), our drivers accept a ultra-wide input voltage range of 90V to 290V AC (with optional high-voltage cutoff up to 440V AC for 3-phase fault protection). Integrated MOV protection arrays safeguard against heavy voltage spikes and lightning surges.
We support all major global dimming protocols: 0-10V / 1-10V analog dimming, PWM, Triac / Phase-cut dimming, DALI-2 (IEC 62386), D4i, as well as wireless protocols including Casambi, Zigbee 3.0, and Bluetooth Mesh integrations.
We supply full safety documentation including BIS (IS 13252), CE-EMC (EN 55015, EN 61547), CE-LVD (EN 61347-1, EN 61347-2-13), and UL standard compliance documentation. 100% burn-in test certificates and dielectric strength test records are archived for full traceability.
