COTEK SP1500-112 1500 Watt 12 Volt Pure Sine Wave Inverter | Wide Input Voltage Range | Power ON / OFF Remote Control (Green Terminal) | Output Voltage and Frequency Selectable WIDE INPUT VOLTAGE RANGE 10.5-16.5V: With wide input voltages, this equipment fulfills the majority user applications. To make a full use of it's batteries in maximizing the operation time, a wide input range is therefore required. This allows the system to continue operating even when the supply voltage is not stable. And by choosing a wide input range, the same part can be used in several different situations and thereby cutting the costs. POWER SAVING MODE SELECTABLE: SP1500-112 is suitable from different user scenarios to active power saving mode. It allows you to maximise your autonomy. The Power Saving Mode feature will shut off various connections to minimise power consumption by using only the essential and needed functions. INPUT AND OUTPUT FULLY ISOLATION: SP1500-112 offers Input Protection against Reverse Polarity (Fuse), Under Voltage and Over Voltage. It also has a design for Output Protection against Short Circuit, Overload and Over Temperature. With these advanced protection features, it prevents the equipment from electrical shocks. It also has Temperature and Load Controlled Cooling Fan. LOW PROFILE DESIGN: Stylish ID design and saving space for installation. The latest SP series pure sine wave inverter 1500W implements a state of the art design topology with the following advanced functions such as Wide DC input voltage and Wide Operating Temperature to fulfill majority of applications. It has Low profile and stylish design with output voltage selectable switch that makes the product more user friendly. RS 232 PROTOCOL COMMUNICATION: With RS 232, it provides alternative solutions to set the parameters. It also has a built in advance microprocessor to provide friendly interface. It also has the ability to Control "Fault" Alarm and Power ON/OFF remotely using an optional Remote Controller CR-8 / CR-16.
