Highly reliable & durable devices that generate a power supply of 230 V AC at a frequency of 50 Hz from a 12 V or 24 V DC (for instance, from batteries in cars, boats, on a camp site, in garden houses...). The very high inductive load capacity enables electric motors, mobile offices (laptops, etc.), fridges, electronic tools, etc., to be operated. These devices naturally conform to the highest quality & safety requirements & are equipped with overload, overheating, short-circuit, deep discharge & undervoltage protection. As soon as the input voltage sinks below 10.7 V or 21 V the devices trigger an alarm. If the voltage drops below 10 V, the devices switch themselves off. These protection mechanisms optimally protect the power supplies (batteries) as well as the connected devices. ...

Ballast transformer for operation of devices with European safety plug on the U.S. power grid. Due to the different mains voltages & connection systems this has been almost impossible up to now. This series autotransformer overcomes this technical obstacle. The input side with U.S. power cord, the output side with a protective contact socket. ...

Multi-functional meter for switch board mounting It enables the measuring voltage, current, frequency & performance factor Cos-Phi ; the record duration & effective functioning. The meter determines the exact value for effective performance (W), apparent power (VA), idle power (VAr) & power consumption (Wh) by these data. The function takes place via two key buttons. The min.-, max.- & average values are recorded & can be displayed. ...
