Keep all of your devices running smoothly with the APC SMT750RM2U Smart Uninterrupted Power Supply. 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 spikes, surges, lightning, and other power disturbances. This device also features an automatic self-test feature, which provides periodic battery self-tests to ensure early detection of a battery that needs to be replaced, LED status indicators, and USB connectivity. This UPS also provides adjustable voltage-transfer points, which maximize useful battery life by widening the input voltage window or tightening the output voltage regulation, and adjustable voltage sensitivity, which provides the ability to adapt the UPS for optimal performance in specific generator applications or power environments. The Green Mode will bypass unused electrical components in good power conditions to achieve high operation efficiency without sacrificing any protection, and high online efficiency generates less heat and reduces utility costs.
