Sophisticated control and protection Tavrida Electric reclosers provide protection from various faults, including short circuits, earth faults, high impedance earth faults, broken wires, islanding, incorrect tap changer operations, network overload and over or undergeneration. Embedded RTU and metering ensures the reclosers are SCADAready with no additional expenses. TELARM® Dispatcher and DualSCADA TELARM® Dispatcher is proprietary remote control and monitoring system that works as a standalone SCADA and/or in parallel with an existing SCADA system, acting as a backup method of controlling and monitoring reclosers. TELARM® Dispatcher offers a number of features not available with most conventional SCADA systems, such as remote access to system logs, fault and load profiles and the remote control of protection settings. With maintenancefree design rated to perform 30,000 open and close operations, Tavrida Electric reclosers keep expenses to a minimum over their entire lifespan.

Magnetic field sensors are used in particular for contactless detection of the piston position in pneumatic cylinders. Using a patented operating principle, our magnetic field sensors detect permanent magnets of different strength attached to the piston in all common cylinders error-free. The sensors operate wear-free, are short-circuit proof, rugged and IP67 rated. We also offer solutions for use in welding or hazardous areas as well as for analog queries.

The power supply units of the PSU67 series are IP67 rated and can be mounted in the field. The devices bypass short power drops of maximally 50 independently. In addition, no-load and short-circuit protection as well as the passive air cooling increase the fail-safety of the devices. The output current is - depending on the type - 2 A, 4 A or 8A. Thanks to their universal AC/DC input, the power supplies can be used worldwide in numerous networks. The high efficiency of up to 90% provides a good energy balance.

The sun | power VR M battery is particularly suitable for village power supply, security lighting, UPS systems and home storage. By using HOPPECKE ESS technology, the sun | power VR M battery offers excellent cycle stability and increased service life. Furthermore, the HOPPECKE system connector ensures increased short-circuit safety. Sun | power VR M is maintenance-free regarding water refilling.

The electronic temperature switch of BEDIA is fitted with thin-film resistor Pt 1000 in a bridge circuit. This sensor element provides close switch point tolerances and a quick response. Switch point and reset hysteresis may be selected within the admissible operating range when ordering so as to allow the monitoring of both very wide and very close temperature ranges. The switching output is protected from short-circuit and overload. The short-circuit current is limited by the output transistor switching off inthe event of a fault. It will automatically reset as soon as the fault has been remedied. The switch is available with ground-connected, plus-connected or potential-free DC switching output. The switch is open in the event of power failure or disconnection of the power supply, independed of the switching function. It is available both as normally open (NO) or normally closed (NC) switch.
