PRODUCT DESCRIPTION
Samlex NTX-3000S-12 3000W Pure Sine Wave Inverter – 12V DC to 115V AC
The Samlex NTX-3000S-12 is a compact 12 V DC to 115 V AC pure sine wave inverter that delivers 3000 W of continuous power and 6000 W of surge power. It provides reliable, clean power for a wide range of applications, and the included LCD remote control makes it easy to monitor and operate.
Clean Pure Sine Wave Power
Pure sine wave AC output with high efficiency and very low idle current. The inverter is FCC certified, so electrical interference will not be a problem when operating near sensitive equipment.
Starts High-Surge Loads with Hypersurge Technology
Samlex Hypersurge technology helps the inverter start high-surge loads with ease, supported by 6000 W of surge power.
Three Standard 15A Receptacles
Connect multiple 120V AC household appliances directly to the unit using three standard 15 A receptacles. Each receptacle has its own 15 A circuit breaker to protect your devices and the inverter from overload.
Compact, Quiet and Easy to Connect
The compact, lightweight design is easy to install. A low noise, temperature-controlled variable speed fan keeps operation quiet, and a wide input voltage range adds flexibility.
LCD Remote Control Included
The NTX-RC LCD remote control is included. It is also compatible with the remote used by previous NTX series models, so existing setups work without changes.
Safety Certified
FCC certified and ETL certified to meet strict UL and CSA safety standards.
