Do you need to use 230V equipment from a 24V battery system without installing a large inverter? The Samlex SWI 250-24 is a compact pure sine wave inverter that converts 24V DC to 230V AC. With a continuous output power of 250 watts, it is suitable for smaller 230V devices within its power range.
In addition to the European 230V socket, the inverter features a 5V/2.1A USB port, allowing you to power or charge suitable USB devices directly from the inverter.
The combination of a pure sine wave, compact housing, low standby consumption, and various built-in safety features makes this Samlex an attractive choice for mobile 24V installations in, for example, a truck, commercial vehicle, or boat.
What does the Samlex SWI 250-24 inverter do?
The Samlex SWI 250-24 converts DC voltage from a suitable 24V system to 230V AC ±3% at 50 Hz.
According to the specifications, the inverter accepts an input voltage of 20 to 33V DC and provides a maximum of 250 watts of continuous output power.
This allows you to use equipment that normally runs on 230V in locations where only a 24V battery or battery bank is available.
Why choose a pure sine wave inverter?
The SWI 250-24 produces a pure sine wave output voltage. This waveform closely mimics that of the regular power grid, making the inverter suitable for a wide variety of 230V devices within its power specifications.
For mobile applications, this is practical when you want to use different types of equipment and require a clean, sinusoidal 230V output.
Always check the power consumption of your device before connection. The maximum continuous output of this Samlex is 250 watts.
What can you use the Samlex SWI 250-24 for?
This compact inverter is intended for situations where a 24V electrical system is present and you need 230V or USB power.
Examples include:
- In a truck or commercial vehicle with a suitable 24V battery system
- On board a boat with a 24V electrical system
- For mobile work and service installations without direct grid access
- For smaller, compatible 230V devices with a power demand up to 250 watts
- For powering or charging suitable USB equipment via the 5V/2.1A USB port
230V and USB from a single inverter
A practical advantage of the Samlex SWI 250-24 is that it provides more than just a 230V output.
On the front panel, next to the European VDE socket, there is a 5V USB port with up to 2.1A. This allows suitable USB devices to be connected directly without needing an external 230V USB adapter.
This makes the inverter particularly practical for mobile installations where efficient use of available connections and space is required.
What safety features does the Samlex SWI 250-24 have?
The SWI 250-24 includes various protective functions for both the inverter and the electrical system.
According to the product specifications, there is protection against low input voltage, high input voltage, overtemperature, overload, and short circuit.
The overload protection features an automatic reset. Additionally, there is an alarm and shutdown function for low battery voltage.
LED indicators provide information on the power and protection status. The built-in fan is temperature-controlled, ensuring active cooling is used when needed.
Compact design with low standby consumption
With dimensions of 235 x 112.4 x 45.9 mm and a weight of approximately 0.89 kg, the SWI 250-24 is a compact inverter.
This is especially useful when mounting space in a vehicle or boat is limited.
Its own power consumption is also relevant when running off a battery. A standby current of less than 0.7 amps is specified for this inverter.
The Samlex also features a standard on/off switch, so you can easily turn the inverter off when it is not needed.
What does ECE-R10 mean for this Samlex inverter?
In the product specifications, the Samlex SWI 250-24 is noted as ECE-R10 approved.
ECE-R10 relates to the electromagnetic compatibility of electrical and electronic equipment for vehicles. For an inverter used in a mobile vehicle environment, this is therefore a relevant product feature.
