WLD-900V135A90KW67H-BB is a liquid-cooled bidirectional DC-DC converter, delivered by Wenlida Power Electronics with an all-digital design and dual-loop voltage/current feedback. It is a buck-boost design where input/output are only for labeling convenience and energy flows bidirectionally. Both LV and HV sides are configurable, 0-950Vdc (rated 600V), max 135A (150A for 10 minutes), max 100kW, symmetric on both ends. Conversion efficiency is >97% at rated power, voltage accuracy ±0.5%FS, quiescent loss only 20mA (no-load), and auxiliary power 220VAC or DC customization. The product uses liquid cooling (inlet ≤60℃/outlet ≤70℃, rated flow 15L/min, CQC18 male connector), IP67 high protection, -20~+60℃ operating temperature and up to 4000m altitude. It supports HV over-/under-voltage protection, reverse-polarity protection, LV over-current/over-voltage/under-voltage/over-temperature/short-circuit protection and droop-parallel customization; both ends start from 0V. Start-up and voltage/current control can be remotely configured via CAN or RS485 (Modbus RTU). It suits high-voltage DC conversion, DC micro-grids, energy storage, special vehicles and high-protection on-board/aerospace power.
