Product Details
Product Overview
The 150W 29.4V 5A / 25.2V 6A Power Adapter delivers regulated 29.4V DC at up to 5A, designed for applications that require continuous, reliable power in a compact form factor. The universal AC input (100–240Vac, 47–63Hz) ensures compatibility with power grids worldwide, while the standard 5.5×2.1mm DC barrel connector mates directly with most 29.4V equipment. Measuring just compact footprint, the 29.4V 5A Model fits neatly into tight enclosures and equipment racks without obstructing adjacent outlets，

Design & Build Quality
The 29.4V 5A Model employs a high-frequency switching topology with premium 105°C-rated capacitors, achieving 88% energy efficiency (DoE Level VI) and keeping surface temperature below 50°C under continuous full load. This thermal headroom makes the model suitable for enclosed cabinets, equipment racks, and installations where airflow is limited. The fanless design ensures completely silent operation — no mechanical noise in studios, offices, or bedrooms.
Typical Applications
With 150W of continuous output, the 29.4V 5A adapter is built for 7S lithium battery systems and other 29.4V DC equipment
E-bikes and e-scooters — charges 7S (29.4V) lithium packs at up to 5A, with CC/CV output that follows the battery's charge profile.
Robotic mowers and AGVs — powers the charging dock and on-board battery pack of autonomous equipment.
Portable power stations — 7S battery modules in portable and backup power products.
Industrial battery strings — 7S packs in floor-cleaning robots, medical carts and mobility devices.
Test and burn-in equipment — a stable 29.4V rail for battery test fixtures and aging racks.
Safety & Protection
Four independent protection circuits in the 29.4V 5A Model operate autonomously to safeguard both the unit and connected equipment:
• Over-Voltage Protection (OVP) — Shuts down output if voltage exceeds safe threshold; auto-recovers when fault clears.
• Over-Current Protection (OCP) — Limits output current to prevent damage from overloaded downstream wiring.
• Short-Circuit Protection (SCP) — Instantly cuts output when a short circuit is detected.
• Over-Temperature Protection (OTP) — Thermal shutdown activates if internal temperature exceeds design limits; resumes once cooled.
All protection modes are non-latching — the model automatically restarts after the fault condition is removed. Full UL/CUL, FCC, CE, and CB certifications support compliance for commercial, industrial, and residential installations worldwide.
Warranty & Technical Support
Every 29.4V 5A Model carries a 3-year warranty covering manufacturing defects. Technical support assists with compatibility verification, cable length selection, and connector configuration. OEM and ODM services are available for custom branding, cable lengths, and plug styles on bulk orders (MOQ 100 pcs, 7–10 day lead time).
