Broad-range power supply 24 to 110 V DC (+/-25 %) and 110 to 230 V AC (+/-10 %)
Standards-compliant personal and plant protection Protective separation according to EN 61140
3-port isolation Prevention of incorrect measurements caused by potential differences
Ideal value for money High accuracy and isolation – 2.5 kV AC test voltage
Easy installation DIN rail bus connectors allow for easy and extremely cost efficient connection of the power supply to several VariTrans A 21000 or other Knick products in 6 mm housings.
Cost reduction with smaller enclosure More channels per meter DIN rail thanks to space-saving 6 mm housing and closely packed mounting
Long service life Extremely low failure rate (MTBF of 280 years) due to reduced self-heating
High accuracy and temperature stability Gain error 0.2 % and temperature coefficient 0.01 %/K
Calibrated range selection without complicated readjustments
Easy configuration DIP switch accessible from outside
Adjustable or fixed-range models
International use UL approvals for US and Canada
The VariTrans A 21000 isolates, transmits and converts 0 to 20/4 to 20 mA and 0 to 10 V with a high level of accuracy. In spite of its modular housing being only 6 mm wide, the new VariTrans isolation amplifier provides maximum protection of personnel and equipment through protective separation up to a working voltage of 300 V conforming to EN 61140. The test voltage is 2.5 kV AC. It can be supplied with either 24 V DC or 230 V AC.
