Core Advantages
The TDC-IY series is a high‑reliability DC-DC converter designed for electric vehicles, industrial equipment, and battery backup systems. It converts high‑voltage DC (from 72V to 320V battery packs) to a precise 14V DC output, ideal for powering 12V auxiliary loads (lights, controllers, fans, infotainment).
Compact dimensions: 278(L) x 116(W) x 74(H) mm
Net weight: only 2.5kg — easy integration.
Natural cooling: no moving parts, silent operation, higher reliability.
