Keep your devices running smoothly with the APC SMT1500 Smart-Uninterrupted Power Supply - 120V - 980 Watt - (8) NEMA 5-15R in black. This UPS simulates utility power to provide the highest degree of compatibility for active PFC servers and sensitive electronics. This UPS will also protect connected loads from lightning, spikes, surges, and other electrical disturbances. This device also offers an automatic self-test feature, which provides periodic battery self-tests to ensure early detection of a battery that needs to be replaced, an LCD interface, LED status indicators, and USB connectivity. This device also provides adjustable voltage sensitivity, which provides the ability to adapt the UPS for optimal performance in specific generator applications or power environments, and adjustable voltage-transfer points, which maximizes useful battery life by widening the input voltage window or tightening the output voltage regulation. The Green Mode will bypass unused electrical components in good power conditions to achieve high operating efficiency without sacrificing any protection, and high online efficiency generates less heat and reduces utility costs.
