Description

1U 1200W pure sine wave inverter is designed for rack mount installation. The unit features 24V/48V input AC and provides stable & clean power that is perfect for use in telecommunication and communication applications. The term ‘1U’ means one unit of rack mount, which equals 44.45 mm.

•  It is MCU-based and capable of providing power for resistive, capacitive, or inductive loads with high stability.
• It has a built-in Transfer Switch function that synchronizes with wall power. When a blackout occurs, power from batteries can be supplied immediately to load.
• It provides RS-232, USB, and Ethernet ports for firmware updates and real-time inverter status monitoring.
• Safety Protection: Including Overtemperature protection, short circuit protection, input reverse polarity protection, etc.

Besides the 1U 1200W pure sine wave inverter, Welltron has the capability to offer a wide range of other rack mount inverters for different applications and requirements, as we have professional inverter experts with over 40 years of experience. Please do not hesitate to contact us for technical support or for a special requirement. We would be more than happy to hear from you.
