General Measuring device for testing operating times of low-, medium- and high-voltage switchgear devices, relay description contacts, contactors and switch disconnectors. Implemented operating modes • Operating times • Synchronism of contact opening operations / contact closing operations • Coil currents • External triggering via an auxiliary contact input Control Electronic switching outputs (IGBT) for single-phase control of the closing and opening coils. outputs All operating sequences can be configured and output in increments of 50 ms. Outputs protected against overvoltage, overload and overheating, galvanically isolated 2.5 kV Voltage detector 12...300 V AC/DC control outputs Measurementinputs General Recording Binary inputs Main contacts Auxiliary inputs Resolution Accuracy Coil current Measuring range Resolution Accuracy Inputs protected against overvoltage, overload and overheating, galvanically isolated 2.5 kV Interfaces Connection sockets 1 x control outputs coils Cable sets with 4 mm safety 1 x binary inputs main contacts/AUX switchgear device User interfaces Control panel with graphical display, one-handed operation, separate key for each test mode. Communication Bluetooth/Android/IOS External power supply 24 V / 0.5 ADC; 15 W (Power supply units from 9-30 VDC can be used) Integrated batteries Microprocessor-controlled monitoring Battery life for up to 18 hours Technical specifications subject to change without prior notice | ©02/2025 KoCoS Messtechnik AG www.kocos.com Doc. 7612011 Rev. 1.10
