Do you have access to a 230 Volt connection, separate from the fixed network or general infrastructure? Always take your own 230 Volt connection everywhere you go, independent of others? That is possible with these Professional Pure Sine Voltage Converters from HBM!

Power anywhere; in the camper or caravan, on the boat, in the handy bus, or even in your tent at the campsite. All you need is a 12 Volt battery and one of these inverters!

HBM offers a wide range of high quality pure sine wave inverters in various capacities:

300 Watts / 600 Watts / 1000 Watts / 1500 Watts / 2000 Watts / 3000 Watts

All professional pure sine wave inverters are actively cooled by an internal fan and passively cooled by the cooling fins on the housing. All pure sine wave inverters are equipped with the following protections: Overheating / overload / undervoltage (if the voltage of the battery falls below 10.3 V, the inverter switches off). If the inverter goes into protection, the red LED on the front will light up and a sound signal will sound.

In addition to one or more 230V connections, the sine wave inverters are equipped with one or more USB connections to charge USB equipment. All inverters are supplied with spare fuses and cabling (for the 12 Volt side).

What is a pure sine wave inverter?

The power grid as we know it at home consists of alternating current. That is current (voltage) that alternates between -230 Volt and +230 Volt. This change is a result of the rotating generator that generates the power in the power plant. Internationally, it has been agreed that this change takes place 50 times per second. The frequency of the change is therefore 50 Hz. The switching itself happens gradually. This means that the voltage rises from -230V to +230V and back again in a smooth wave motion. This flowing wave describes the shape of a sine wave. A generator is a mechanical device and has no trouble generating a perfect sine wave; that is a result of its rotating movement.

Now, however, we want to turn a 12 Volt battery (power source) into an alternating (50 Hz 230V) voltage that resembles that of a generator. Generating a perfect sine wave electronically is not so simple. Often, for reasons of cost, one chooses to approach the sine wave and not to imitate it perfectly. This is the case with the so-called modified voltage converters. These modified converters therefore do not have a smooth build-up and breakdown of the voltage. The construction and dismantling then takes place in small steps.

With the pure sine wave inverters the shape of the alternating voltage wave is therefore a real smooth sine wave.

Why a pure sine wave inverter?

Many equipment that is plugged into the wall outlet assumes that the voltage changes in a smooth sine wave. That is allowed, because that is after all an international agreement. However, if the voltage does not alternate with a perfectly smooth sine wave, but "jumps" up and down in small steps (as with a modified voltage converter), very small voltage peaks occur when the device is placed on such a stepped AC voltage is inductive. Examples of inductive equipment are transformers (adapters) and electric motors (roughly: anything with a coil in it). These very small voltage peaks are bad for the inductive equipment and shorten the life of such equipment. Sometimes an inductive device can even immediately malfunction if it is connected to a modified alternating voltage (eg LED drivers and other sensitive electronic equipment) and sometimes the equipment just lasts a long time. Resistive equipment (equipment with only a resistance character) can withstand connection to a modified inverter. Most other devices (such as motors and transformers) will hum slightly (sometimes loudly) if they are connected to a non-perfect sinusoidal AC voltage.


In summary: A pure sine wave inverter is safer for the devices that are connected to it. All devices can be connected to a pure sine wave inverter without any worries.
Connecting inductive equipment to a modified voltage converter can cause the equipment to burn out immediately or shorten its lifespan or (in the least severe case) often hear a hum in the device.
