Votronic 3178 SMI 1200 12V 230V ST-NVS MobilePower Inverter

The Votronic MobilPower SMI 1200 Sinus ST-NVS inverter 12 V DC / 230 V AC is designed for use in special vehicles, high-quality motorhomes, and other areas where high quality and reliability are required. It is designed for high continuous loads and delivers 1200W continuously and up to 2000W short-term peak power for handling high starting currents.

ST-NVS with integrated mains priority circuit

A special highlight of the SMI ST-NVS series is the integrated mains priority circuit. Thanks to this, your power system automatically draws its energy from the mains when connected to the power grid, thus conserving the batteries. If no mains power is available, the device automatically switches back to battery operation. The exact behavior of the NVS can be flexibly adjusted so that different configurations can be implemented as required.

The SMI 1200 ST-NVS: modern inverter technology from Germany

The devices operate according to the latest technology in a switched mode design. Microprocessor control in conjunction with modern SMD technology has made it possible to achieve a compact design. Noise- and friction-optimized smooth-running fans (speed-controlled) ensure perfect cooling and thus trouble-free continuous operation even at full power. Integrated protective circuits also monitor the thermal and electrical load as well as overloads and short circuits in the output circuit. The inverters feature intelligent power-saving control with automatic shutdown. This ensures that no more power is consumed in idle mode than is absolutely necessary. To protect the batteries, an undervoltage protection system is integrated, which switches off the inverter when the battery voltage drops.

flexible installation of the inverter display panel possible

To position the inverter optimally, the display panel can be removed by removing the two mounting screws and then reinserted in the desired position (rotatable in 90° increments) and screwed back in place. If the inverter is installed in a location that is difficult to access, the display panel can also be used as a remote control. To do this, remove the control panel from the device, reconnect it to the device using the 5 m control cable, and mount it in the desired location.

Optionally, an additional remote control can also be connected if you want a display directly on the device and in the board area.
