A 24V PSU (Power Supply Unit) converts AC input into stable 24V DC output for industrial automation, LED lighting, CCTV, and machinery. Shenzhen-based manufacturers like Wecent provide GaN-enhanced 24V PSUs with high efficiency, OEM customization, and global certifications. Low MOQs from 200pcs allow B2B wholesalers and suppliers to scale quickly with reliable, compact, and globally compliant solutions.
How Does a 24V PSU Work?
A 24V PSU uses switch-mode power supply (SMPS) technology. Incoming AC is rectified into DC, boosted through power factor correction (PFC), then regulated via transformers and feedback loops to deliver precise 24V output (±1%). Wecent integrates GaN transistors to reduce heat, increase efficiency above 95%, and maintain high-density designs suitable for OEM applications. Soft-start, EMI filtering, and parallel redundancy ensure reliable performance in industrial and harsh environments.
What Are the Key Specifications of 24V PSUs?
Important specifications include output power (50–1500W), ripple (<100mV), efficiency (>90%), wide input voltage (85–264VAC), and protections such as overvoltage, overcurrent, and overtemperature. Wecent’s GaN models provide adjustable outputs (±10%), remote monitoring, and DIN-rail mounting, ensuring 99.5% uptime and scalable solutions for B2B wholesale.
| Specification | Typical Range | Wecent GaN Model |
|---|---|---|
| Power | 100–960W | Up to 1000W continuous |
| Efficiency | 90–96% | 95%+ GaN |
| Ripple/Noise | <120mV | <50mV |
| MTBF | >200,000 hrs | 500,000 hrs |
| Warranty | 1–3 years | 2 years standard |
What Are the Benefits of 24V PSUs?
24V PSUs provide stable, energy-efficient power for industrial systems, reducing downtime and operating costs. Wecent’s GaN-enhanced units are 40% smaller, 25% more cost-effective, and suitable for harsh conditions, supporting scalable parallel operation and battery backup. Shenzhen factories ensure rapid prototyping, global certification compliance, and OEM flexibility, making these PSUs ideal for B2B suppliers and wholesalers.
Which 24V PSU Should You Choose?
Select based on power requirements, mounting type (DIN-rail), and features like active PFC or redundancy. Wecent recommends 480W single-phase PSUs for automation and 960W units for high-power LED or industrial applications. Prioritize GaN technology for high efficiency (>93%) and heat reduction. OEM customization from Shenzhen factories ensures voltage tailoring and multi-output configurations to match specific loads.
Why Choose China Manufacturers for 24V PSUs?
China-based manufacturers offer cost savings of 30–50%, large-scale production, rapid 4-week delivery, and full certification support. Shenzhen hubs like Wecent provide GaN expertise, OEM flexibility, and bundled accessories, including cables and enclosures. With 15+ years of experience and 200+ global clients, Wecent ensures reliable, scalable supply for B2B wholesalers and global suppliers.
How to Source Wholesale 24V PSUs from China Factories?
Engage verified factories with detailed RFQs, request samples, verify certifications, and negotiate MOQ and pricing. Wecent streamlines the process with online quoting, design-for-manufacture reviews, and bundled accessory options. Steps include inquiry → sample approval → tooling → bulk production with a deposit. Shenzhen logistics ensure DDP delivery worldwide, enabling fast, scalable B2B operations.
What Are Common Applications for 24V PSUs?
24V PSUs power PLCs, HMIs, LED lighting, CCTV systems, access control, solar inverters, EV chargers, and medical or telecom equipment. Wecent manufactures rugged units for industrial, marine, and warehouse environments. Wholesalers leverage these units for machine automation, security systems, and high-density LED installations, benefiting from versatile, reliable DC power.
How Do GaN 24V PSUs Compare to Traditional SMPS?
GaN PSUs switch faster, reducing size by 50%, improving efficiency to 96%, and minimizing heat dissipation. EMI is lower, making them suitable for dense industrial or automation setups. Wecent’s GaN 24V PSUs achieve 1000W in half the footprint of silicon-based units, providing high power density and cost-effective, OEM-ready solutions for global B2B partners.
| Aspect | Traditional SMPS | Wecent GaN PSU |
|---|---|---|
| Size | Standard | 50% smaller |
| Efficiency | 88–92% | 94–96% |
| Heat Dissipation | High | Minimal |
| Cost per Watt | Higher | Lower TCO |
| Power Density | 10W/in³ | 20W/in³+ |
