HV-Isolation Amplifier / Transducer DK 8400
Conversion and Isolation of Voltages up to ±1000 V
The HV-Isolation Amplifier/Transducer DK 8400 is used for conversion and galvanic isolation of bipolar und unipolar Voltages up to ± 1000 V DC.
- Excellent transmission characteristics
Precise conversion of unipolar and bipolar input and output signals - Easy commissioning
Ready to use without any settings or adjustments - High bandwidth, high accuracy
No distortion, no falsification of measured signal, optional with filter function - Universal power supply for 20...253 V AC/DC
Applicable world-wide for all common supply voltages - True 3-port Isolation
Protection against erroneous measurements due to parasitic voltages or ground loops - Extremely compact design
12.5 mm housing with plug-in screw terminal blocks - 5 Years Warranty
Defects occurring within 5 years from delivery date shall be remedied free of charge at our plant
The order key allows you to select the desired input and output ranges to which the unit will be adjusted at the factory before delivery. If required a measuring range compensation can be performed using the Zero/Scan potentiometers on the front of the device.
The slim housing with 12.5 mm width saves space in your switch cabinet and facilitates by the practical plug-in screw terminal blocks the assembly.
The new universal power pack for 20 to 253 V AC/DC means the DK 8400 can be used anywhere in the world, with all mains power supplies. A green LED on the front of the unit has been provided to monitor the power supply.
Analog signal processing ensures precise measurements with fast response times and excellent signal reproduction at the output, with an optional filter function.
The high efficiency of the innovative circuit technology significantly reduces the device’s self-heating. This results in extremely high reliability and long-term stability.
