Dold LK5895.12/011/61 DC24V 1k-250k, Insulation monitor, sku: 0065928

The insulation monitor LK 5895 of the VARIMETER IMD family is a solution for optimal insulation monitoring of modern IT systems. The device can be used in the most flexible way for AC, DC and AC/DC systems even with large leakage capacity to earth (PE). The adjustment of the setting values is simple and user friendly done on 2 rotary switches on the front of the device. Via LEDs the measured value, device parameters and device status are indicated easy to read.

• Insulation monitoring according to IEC/EN 61557-8
• Detection of symmetric and asymmetric insulation faults
• Measuring circuits can be disconnected via control terminals, e.g. for mains couplings
• 1 changeover contact each for prewarning and alarm
• Prewarning threshold setting range: 20 kΩ ... 2 MΩ
• Alarm threshold setting range: 1 kΩ ... 250 kΩ
• Energized or de-energized on trip can be selected for output relay
• Setting the maximum leakage capacitance to shorten the response time
• Simple, clearly arranged adjustment of the device with screwdriver
• LED chain to indicate the current insulation resistance
• Display of active measuring circuits
• Automatic and manual device self-test
• Alarm storage selectable
• External test and reset pushbutton can be connected
• Width 90 mm
