Topology Non-isolated boost
Dimensions: 215×100×78mm (21.5×10×7.8cm)
Features:
True 5KW rated power (sustained 5KW output requires input >200V; max 2.6KW at 130V input)
Wide DC input range: 130V – 330V
Adjustable constant-voltage output: 340V – 385V DC
Non-isolated boost topology, ideal as pre-regulator for inverters
Built-in protections: pre-charge circuit, input fuse, reverse polarity protection, output anti-backflow, over-temperature shutdown
Designed for low-voltage battery bank step-up to supply DC bus for inverter front stage
Note:
This module is intended as a front-stage boost converter for inverters. Output is constant voltage – DO NOT use for charging batteries.
For continuous 5KW output, ensure input voltage >200V DC and adequate cooling (forced air cooling recommended above 2KW).
Derate output power when input voltage is below 200V (e.g., 2.6KW max at 130V).
Non-isolated design: input negative is common with output negative. Pay attention to safety and insulation.
Pre-charge function reduces inrush current during startup. Reverse polarity protection will activate but always connect correctly.
Do not exceed output voltage range or connect loads that may back-feed voltage beyond specifications.
