IR140Y |
 Ground Fault Monitor for Ungrounded Single-phase AC systems to 300V AC
|
|
The IR140Y series monitors the insulation resistance of ungrounded AC systems up to 300 V. The response value is steplessly adjustable via a potentiometer and DIP switches. Many different supply voltages in either AC or DC are available.

IR420-D4 |
Ground Fault Monitor for Ungrounded Single-phase AC systems to 300V AC
|
|
The IR420 series is designed to monitor the insulation resistance of ungrounded AC systems up to 300 V. The response range is steplessly adjustable from 1kΩ to 200 kΩ. Values are displayed and settings are changed via an LCD seven segment display. A large range of supply voltages can be applied to the unit. Connecting an external supply voltage allows for de-energized systems to also be monitored.
