Sentinel Power

On-line Double-conversion Uninterruptible Power Supply 700VA – 3000VA

Sentinel Pro (SEP) provides maximum online UPS protection to your critical servers, data processing IT systems and telecoms networks. Single-phase UPS guarantees high-quality power (0.99 pf). Easily handles a wide range of input voltages (140-276V) and has a high overload capacity (150%). Compact design and fuss-free installation make it a great choice for protecting Edge applications

For long runtime applications, Sentinel Pro (ER models) can be fitted with matching battery extension packs which also include additional battery boost chargers.

The UPS is highly efficient. SENTINEL PRO is designed to save energy and has a power-off push-button feature to reduce energy consumption to zero, when no load is connected or switched off. Sentinel Pro models include 700VA, 1000VA, 1500VA, 2200VA and 3000VA.

In terms of communications, each Sentinel Pro has a built-in mimic panel with an LCD to show input and output voltages, and battery charge status. The inverter is a totally new design, fully microprocessor controlled and constructed to achieve the highest levels of operating efficiency and configuration options. SENTINEL PRO UPS also have USB communication ports as standard, with a built-in expansion slot for additional adapters, protocol converters and relate contact cards.

Runtime Expandability 

Optional battery extension packs can be connected to increase UPS runtime. In addition, the Sentinel Pro range includes
ER versions with no internal batteries and more powerful battery chargers for longer runtimes.

Low Noise Level

Thanks to the use of high-frequency components and load-based fan speed control, the noise produced by the UPS is less than 40 dBA.
