DC Power Adapter

5V DC Output | 1.5A (7.5W) | Interface: Mini-USB (Mini-B)

This high-performance switching power supply (SMPS) engineered for devices utilizing the Mini-USB (USB Mini-B) power interface. Delivering a stable 7.5W output, this adapter is designed to provide clean, ripple-free current to sensitive digital devices. Unlike standard consumer chargers, this unit is built for continuous duty, featuring industrial-grade components to ensure long-term voltage stability.

Technical Architecture & Protection

• Mini-USB Power Delivery: Specifically wired for power delivery via the Mini-B interface. Ideal for legacy hardware that requires a higher amperage (1.5A) than standard computer USB ports (typically 0.5A) can provide.

• EMI/RFI Suppression: Integrated filtering circuits prevent electromagnetic interference, making it suitable for use near medical equipment, radio receivers, or high-accuracy sensors.

• Safety Suite:

  • Over-Voltage Protection (OVP): Safeguards the connected device against internal component failure.

  • Short Circuit Protection (SCP): Automatic shut-down and recovery logic.

  • Over-Current Protection (OCP): Limits current to 1.5A to prevent thermal stress on the device's charging circuit.
