The CET Power E-One 1000VA Series DC/AC Inverter is a high-efficiency power conversion solution, engineered to meet the demands of critical AC applications in telecommunications, transport, and public safety. Delivering 1 kVA (0.8 kW) of pure sine wave power from a 48 Vdc input, this inverter ensures reliable and stable performance in environments where uninterrupted power is essential. Its compact, lightweight design makes it suitable for rack, wall, or desk mounting, even in space-constrained setups.

Key features include a dual-input option for DC or by-pass AC power, low voltage ripple for extended battery life, and advanced safety mechanisms such as short circuit and reverse current protection. Achieving up to 91% efficiency in DC/AC mode and 99% efficiency in AC/AC by-pass mode, the E-One minimises energy loss while delivering consistent output. Its intelligent cooling system with a variable-speed fan reduces maintenance needs and enhances operational durability. The robust design supports operation from -20°C to 65°C, ensuring reliability under harsh conditions.

Ideal for applications such as 5G telecom base stations, mass transport signaling systems, CCTV traffic monitoring, and emergency radio networks, the E-One 1000VA Series provides dependable performance in critical scenarios. Fully compliant with international safety and EMC standards (IEC60950, EN55022 Class A), it meets rigorous quality benchmarks for industrial and professional use.

Choose the CET Power E-One 1000VA Series DC/AC Inverter for an efficient, compact, and versatile solution to power your critical AC equipment with confidence and reliability.
