Smart-UPS C 1000/1500/2000/3000 VA 120/230 Vac Rack-Mount 2U

SMC10002U, SMC15002U specifications

The APC SMC15002U and SMC10002U are rugged and reliable line interactive UPS (Uninterruptible Power Supply) systems designed to keep your critical electronic equipment operational during power disruptions. These UPS units are part of APC’s Smart-UPS family, renowned for their efficiency and effectiveness in protecting sensitive electronics in office and home environments.

One of the main features of both models is their ability to deliver pure sine wave output. This ensures that connected devices receive clean power, which is crucial for sensitive equipment like servers, networking hardware, and telecommunications systems. This feature significantly reduces the risk of damage or malfunction in sensitive electronics compared to standard modified sine wave UPS systems.

The SMC15002U offers a capacity of 1500 VA/900 W, while the SMC10002U provides 1000 VA/600 W. This flexibility allows users to select a model based on their specific power requirements, catering to various applications from small businesses to home offices. Both models incorporate Automatic Voltage Regulation (AVR) technology, which stabilizes voltage fluctuations by automatically adjusting the incoming voltage. This feature helps ensure that connected devices operate consistently and enhances their lifespan.

Battery management is another strong point of the SMC series. These UPS models utilize intelligent battery management systems that prolong battery life and provide notifications for battery replacement. The user-friendly LCD interface displays real-time information about the UPS's status, including battery capacity, load level, and input/output voltage levels, allowing for seamless monitoring.

Furthermore, the SMC15002U and SMC10002U include multiple outlets, providing ample connectivity for various devices. They also have a compact rack-mountable design, which is ideal for data centers and network closets where space is at a premium. The ability to integrate with network management systems through optional accessories allows for remote monitoring, enabling IT administrators to respond to power events swiftly.

In summary, the APC SMC15002U and SMC10002U are advanced UPS solutions that combine high-capacity power, pure sine wave output, AVR technology, and intelligent battery management to protect critical electronic equipment. Their robust features and reliability make them a valuable asset for anyone looking to safeguard their investments in technology against power interruptions.
