The Powercom Vanguard VGD-1500 is an online double conversion UPS designed to provide a continuous, stable power supply for sensitive electronic equipment. With a capacity of 1500VA and 1050W, it ensures a seamless transition during power failures thanks to a 0 ms transfer time and a pure sine wave output, which protects your hardware from voltage fluctuations and electrical noise. The system handles a wide input voltage range and includes built-in lightning, surge, and short circuit protection to keep your devices safe from external electrical threats. Inside the 16 kg chassis, you will find three 12V 9Ah sealed, maintenance-free batteries that can be hot-swapped by the user without powering down the system. These batteries are managed by an advanced system that allows for charging even when the UPS is turned off, reaching 90% capacity in about 4 hours. You can monitor the status through the front LCD panel or use the RS-232 and USB ports to connect to UPSMON software on Windows or Linux for more detailed management, including scheduled reboots and power failure history. Measuring 225 x 420 x 360 mm, this unit features two IEC-320 C13 outlets and an optional SNMP card slot for network integration. It is a practical choice for professionals needing high-reliability power, offering specialized functions like cold start, emergency power off, and a manual bypass setting for easier maintenance.
