This 19W unit accepts a worldwide AC voltage range from 100V to 240V, eliminating the dangerous voltage drops that cause erratic slewing and potential electronic damage with standard power supplies. Its field-safe design is built around a 2.5m cable and a unique elbowed plug that protects your mount's delicate power socket from accidental damage.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eStable 12.8V \/ 1.5A Output for Mounts Down to -25°C\u003c\/h3\u003e\n\u003cp\u003eStandard power supplies suffer significant voltage loss in the cold; at -10°C, output can drop below 10.5V, forcing your mount's electronics to draw excessive current.
