SVN Hour meters

SVN-2 hour meters measure and display the operating hours digitally to ensure the timely maintenance and monitoring of the remaining service life of the tractor and road-building machinery, equipment, electrical installations and units (UV bactericidal devices, machine tools, chillers, compressors, stand-alone power plants, pumps, generators. etc.). The elapsed time metered in real-time hours is displayed on a digital LED or LCD display accurate to tenths of an hour, if activated. In case of power failure, the readings will be stored in the nonvolatile memory. The meters (depending on their version) are fed from a power supply of 12/24 VDC or 230 VAC. Versions SVN-2-3.1, SVN-2-3.2, SVN-2-05.1, SVN-2-05.2 The elapsed time is counted and displayed on a non- stop basis (if activated). SVN-2-01-3.1, SVN-2-3.21 The elapsed time is counted only if the DC or AC voltage is fed at the additional terminal C (to count the operating hours when the motor is on or when the equipment operates in a particular mode). SVN-2-02-3.1, SVN-2-3.22 The elapsed time is counted only if the AC voltage is fed at the additional terminal C (e. g. AC voltage of the generator or speed sensor), thus minimizing the risk of unauthorized increase in operating hours. Features high accuracy 6-digit LED display, 9.2 mm high silent operation no moving parts wide voltage ranges reliability due to nonvolatile memory (EEPROM) which retains data for 25 years low power consumption The non-resettable 6-digit elapsed time recorder displays time up to 99,999.9 hours. Operable in wide temperature span from minus 40 to plus 70 C° and have hermetic package class IP65. Iinterchangeability with electromechanical indicators. It has bezel with four holes for flush panel mounting.
