Power inverter Voltcraft PSW 300-12-G 300 W 12 V DC to 230 V AC

The Voltcraft PSW 300-12-G 300 W 12 V DC to 230 V AC power inverter converts automotive or battery 12 V DC into 230 V AC suitable for small mains-powered devices. With a continuous output rating of 300 W, the inverter is designed to supply power to chargers, small appliances and portable tools when grid power is unavailable. The PSW model designation indicates a waveform type suitable for many consumer electronics, and the unit includes built-in protection features and a compact housing for ease of transport and installation.

Advantages

The inverter offers stable conversion from 12 V DC to 230 V AC with a rated continuous power of 300 W, enabling operation of a range of low-power AC devices. Integrated protection against overload and short circuit improves safety during use, and the compact, lightweight design supports portability and easy mounting in vehicles or near battery banks. Clear AC output and standard mains socket compatibility make the unit convenient for ad-hoc power supply tasks.

Suitable for

• Charging laptops, mobile devices and camera batteries
• Powering small household appliances such as fans or LED lights
• Operating low-power hand tools and workshop equipment
• Temporary power supply during travel, camping or roadside emergencies

Key specifications

• Continuous output power: 300 W
• Input voltage: 12 V DC
• Output voltage: 230 V AC
• Output waveform: PSW (pure/modified sine designation depending on model details)
• Built-in protection: overload and short-circuit protection
• Cooling method: internal fan or passive cooling (device-dependent)
• Output socket type: standard mains socket for 230 V devices

How to use

Connect the inverter to a 12 V DC source such as a vehicle battery or a 12 V battery bank using the supplied cables or properly rated connectors. Ensure the battery or alternator can supply sufficient current for the intended load and that the inverter is placed on a stable, well-ventilated surface. Plug the 230 V AC device into the inverter’s output socket and switch the inverter on. Monitor the load to ensure it does not exceed the 300 W continuous rating and switch the inverter off when not in use to conserve battery capacity.

Usage recommendations

To prolong device and battery life, avoid running high-startup current appliances such as large motors or compressors. Check the power requirements of connected devices before use and keep the inverter in a dry, dust-free environment with adequate ventilation. Regularly inspect connections for corrosion and ensure the input wiring and fuses are sized appropriately for the expected current draw.
