Read MoreThe Deutronic DVC251 Series DC/DC Converter is a versatile and durable power solution tailored for automotive and industrial applications. Delivering continuous power outputs from 137W to 252W, it ensures stable performance in demanding environments.
Key features include a wide input voltage range (10–154V DC, depending on the model) for compatibility with various power systems and multiple output voltage options (12.5–27.6V DC) with output currents up to 20A. The DVC251 Series features a rugged, fully potted design for enhanced vibration resistance and heat dissipation, as well as galvanic isolation up to 1.5kV for protection against voltage spikes. Advanced protections, such as over-temperature shutdown, short-circuit protection, and reverse polarity protection, ensure reliable operation. Compliance with EMC (EN61204-3) and electrical safety standards (EN61204-7) makes it suitable for harsh automotive and industrial settings.
With a compact and lightweight design (153x131x50mm, approximately 1.5kg), the DVC251 Series is easy to install and integrate. Its high efficiency of up to 90% and wide operating temperature range (-40°C to +75°C) make it an energy-efficient and dependable choice for challenging environments.
