Advantages / Customer benefit

• Preventive fire and system protection
• Quick fault localisation through selective earth fault detection to L+ and L-
• Universal application in non-earthed DC / AC and mixed IT networks
with up to 1000 V nominal voltage
• Suitable for large leakage capacitances up to 3000 μF
• Simplest setting via engaging rotary switches
• For monitoring photovoltaic system, also with thin-film technology
• Optimised measuring times - normally shorter than with known methods
• Monitoring also with voltage-free mains
• Additional measuring circuit allows AC output monitoring even with the
inverter switched off, e.g. with hybrid vehicles
• Measuring circuit with broken wire detection
• No additional coupling device required
• Trigger output for insulation fault locating system
• Analogue output for value of the insulation resistance:
0 ... 10 V / 0 ... 20 mA (2 ... 10 V / 4 ... 20 mA)

The insulation monitor LK 5896 of the varimeter IMD family provides best and up to date insulation monitoring of modern IT systems in an optimum
and state of the art way, fulfilling the relevant standards. 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. The unit has 3 relay contacts to signal
Insulation and device failures. The analogue output provides a voltage and current signal proportional to the actual insulation resistance, which
can be connected to a superior control (plc), another system or external display unit. In addition the LK 5896 provides a second measuring circuit
that can be used to monitor an inverter on the AC side also when the inverter is disconnected.
