Insulation monitoring Special applications
Special Applications
Our product range includes a variety of products tailored to special applications like generators, healthcare facilities or disconnected loads. Our sales engineers are always available for consultation.
| A-ISOMETER® IR420-D6 | |
|---|---|
 |
The offline monitor of the IR420-D6 series is designed to monitor the insulation resistance of loads in the de-energized state. These loads, usually temporarily operated or de-energized most of the time, e.g. fire extinguisher pumps, slide valve drives etc. are supplied from TN, TT or IT systems. During the shut-down periods, hohwever, humidity or other effects may cause insulation faults in the wiring or the loads which may go undetected. |
| A-ISOMETER® IR423 | |
 |
The A-ISOMETER® of the IR423 series is designed to monitor the insulation resistance RF of an unearthed AC system of 0…300 V to earth that is supplied by a mobile generator according to IEC 60364-5-551/DIN VDE 0100-551 (VDE 0100-551). The IR423 is suitable for AC systems with operating frequencies ≥ 30 Hz as well as for AC systems with directly connected DC circuits. The maximum permissible system leakage capacitance Cemax is 5 F. |
| A-ISOMETER® IR5002 | |
 |
The insulation monitoring device of the IR5002 series, continuously monitors the insulation resistance of unearthed DC systems to earth. The device is designed to signal a drop in insulation resistance below a minimum value. |
| A-ISOMETER® IRDH275BM-7 with coupling device AGH675-7 | |
 |
The device combination A-ISOMETER® IRDH275BM-7 and the coupling device AGH675S-7 is designed to monitor the insulation resistance of unearthed medium voltage systems (IT systems). It is suitable for universal use in 3AC, combined AC/DC and DC systems. AC systems may include extensive DC-supplied loads. |
