Welding applications
UL 508 (UR marking)
Using UL94-VO recognized materials
European Directive EMC 89 / 336 / EEC: CE marking
Low voltage directive 72 / 23 / EEC
IEC 61010-1 safety
Remarks:
Each model is multi-range according to primary connection configuration
Bipolar currents measurements when single supplied 0/+5V
These transducers can directly be connected to the 5V input of µ-controllers and instrumentation cards
CASR & CKSR models have an additional pin at the output for more flexibility in applications. This pin provides access to the internal voltage reference which can then be fed to the reference of an A/D converter (Analog Digital) This extra pin can also receive the internal reference (from 0 to 4 V) of the DSP (Digital Signal Processor) or A/D converters commonly used in Power Electronics, allowing cancellation of the reference temperature drift
Low influence in common mode
