Type DataPro, SonicPro, EnerPro Surge Diverter DataPro, SonicPro, EnerPro DataPro, SonicPro, EnerPro - heavy-duty surge diverters for efficient protection of measurement devices and sensors Rail mounting Leakage current of up to 20.000 A Fail-safe performance Surge diverters DataPro 2x1 and SonicPro 3x1 The DataPro 2x1 and Sonic Pro 3x2 surge diverters serve as protection units for the highly sensitive electronics at the end of data, measurement and control cables using 12 4 V DC/ 2 to protect sensors and transmitters. The devices are capable of protecting sensors and transmitters effectively from being damaged due to overvoltage effects. Surge diverter EnerPro for power supply Specifications are subject to change. H:\bs\bs-db-01-en.cdr / Rev. 01 - 20.06.2008 - page 1 EnerPro 2x1 is a surge diverter für 24 V DC supply voltages. The unit serves as protection for single-sided grounded devices with a voltage capacity of up to 6 A.

Containing a two-step protection circuit, the coarse protection is realised by using a gas-filled overvoltage diverter. The precision protection consists exclusively of filter and suppressor diodes. Leakage currents are negligible since no varistors are in uise. This is why remote monitoring or routine checks are not required. The high 20 kA leakage current capacity ensures long lifetimes and high operational safety of the surge diverters. Regular inspection is not necessary due to the use of fail-safe diodes which, in case of error, produce a short-circuit. Hint: In order to connect the protection device to ground, the output side ground connection of the overvoltage limiter should be chosen in all cases as otherwise the limiter cannot fulfill its protective functions as

Type DataPro, SonicPro, EnerPro Surge Diverter EnerPro220Tr/5 and EnerPro220Tr/20 for 230 V supply voltage The overvoltage limiters EnerPro220Tr/5 and EnerPro220Tr/20 serve as lightning and overvoltage protection for 230 V mains supply voltages. The units are housed in snap-on enclosures for 35 mm DIN rails (according to EN 500229) which in addition have a green LED to indicate operating voltage as well as a red LED for the overload display (only EnerPro220Tr/20). EnerPro220Tr/5 and EnerPro220Tr/20 are equipped with a high power, valvetype lightning arrestor as well as with a cut-off circuit...

Overvoltage Protection _Type DataPro, SonicPro, EnerPro Surge Diverter If the leakage current of the overvoltage limiting device is overwhelmed by a current surge, then the base elevates itself over the equipments non-fused ground contact to U = L di/dt. It adds to the limited voltage of the overvoltage protector and gives the electronic input additional charge. However, the equipment’s ground contact should be laid on the leakage potential of the overvoltage limiting device. One more source of errors is a wrongly placed ground connection. It is, therefore, never permissible to fit the ground...
