New earth leakage control system suitable for use in medical environment. It applies a continuous voltage between the secondary of the isolation transformer and the earthing point of the system; in case of an earth fault, it mesures the current and consequently the islation resistance of the circuit. ISO64 is the most complete system for the control of IT systems in medical environment. Further to the standard control of the earth leakage required by EN61558-2-15 standard, also controls rhe impedance of the circuit or, first in the market, checks the proper connection of the relay to the system. ISO-64 systems automaticcally checks the connections of the relay reference to the central tap of the secondary transformer and to the earthing (PE) point. If any of these connections is interrupted, the ALARM LED on the front panel immediately flashes. This signal is really essential, as the lack of these connection may result in a bad performance of the system. ISO64 con be combined with the ISO-64R Remote controls to be installed in 503 switch box, and carry a test and sound off botton, mains light, fault light and buzzer.The max number of remote controls connected to each control system is 4. The single phase isolation transformers TMI64 and three phase isolatin transformers TTI64 are compatible with the system. |
