This document describes the features and characteristics of DPI series products, including single-chip design, compact size, stable output frequency, intelligent temperature protection, and complete overload and short circuit protection functions.
The DPI series combines single‑chip design, simplified wiring and high reliability, offering compact units roughly the size of a palm. Features include stable quartz‑based output frequency, battery low‑voltage auto‑shutdown, reverse‑polarity protection, intelligent temperature protection, and comprehensive overload and short‑circuit safeguards.
Power ratings range from 200 W to 2000 W with input voltage options of 110‑240 V AC. Efficiency exceeds 90 %. Mechanical dimensions vary by model (e.g., 70 × 48 × 155 mm for DPI‑12015) and weights range from 0.58 kg to 2.10 kg. The units provide LED status indicators and audible warnings for low battery, overload, and over‑temperature conditions. This manual is written in Chinese.
