Product overview ISOMETER® - Insulation monitoring devices ISOSCAN® - Insulation fault location systems EDS

Find out today what will not happen tomorrow Reporting critical operating states today, so that unwanted inci- dents such as operational interruptions, costly material damage or even physical injuries do not happen. Safety of power supply To ensure electrical safety for people and electrical installations in an efficient way on a long-term basis, Bender offers insulation monitoring devices for all the key industries. In particular, these devices are used anywhere where a safe power supply is an essential requirement to prevent system failures, eliminate the risk of serious or fatal injuries...

For a high level of operational and electrical system safety: Unearthed power supply systems (IT systems) Modern power supplies require maximum availability, safety and predictive information Given a wide variety of production processes, continuous competitive pressure, the impact of soaring costs and operational availability around the clock, the maximum possible electrical safety for power supplies is required. Although great care has been taken during the design and implementation phases and is continued throughout the maintenance cycle,electrical installations may nevertheless be...

IT systems - information ahead of time ISOMETER®s in IT systems are an effective means of damage prevention, they enable increased productivity and optimised maintenance, which in turn lead to considerable reduction in costs. Bender's wide range of products allows the implementation of individual safety solutions and safeguards your investment.

Device version "Option-W" with increased shock and vibration resistance: Indicated by the letter "W" at the end of the order number.

Main circuits provide the power supply for electrical installations or buildings. These circuits include equipment for generating, converting, distributing, switching and consuming electrical energy. From the user's point of view, different types of loads should be distinguished between: pure AC loads (e.g. motors), AC/DC loads containing electronic components (e.g. converters) and pure DC loads (e.g. battery systems). Example applications AC main circuits with one motor AC/DC main circuits with a variable-speed drive
