GH75-CNxx(-Lxx) DC-DC Power Supply Module – Ultra Wide Input, Isolated Single Output
The GH75-CNxx(-Lxx) series is a compact DC-DC power supply module featuring an ultra-wide 80-1000VDC input range, isolated single output, and 75W continuous power with 120W peak output capability. Designed for energy storage systems, photovoltaic installations, and industrial equipment, it provides reliable power conversion with 4000VAC isolation and advanced protection features.
Product Description
The GH75-CNxx(-Lxx) series is a high-performance DC-DC converter designed for renewable energy and industrial applications requiring stable power conversion across a wide input voltage range. Supporting input voltages from 80VDC to 1000VDC, the module delivers isolated output voltages from 12V to 48V while maintaining efficiency up to 86%.
Built to comply with CE (EN62477-1) requirements, the series incorporates reverse polarity protection, under-voltage protection (UVP), over-current protection (OCP), and short-circuit protection (SCP) to ensure dependable operation in demanding environments. With 4000VAC isolation, compact dimensions, lightweight construction, and no minimum load requirement, it is ideally suited for photovoltaic systems, battery energy storage applications, and industrial automation equipment. Models with the “-Lxx” suffix include pre-installed input and output wires for easier installation.
