Isolation application example
The transducer can be used according to EN 50178 and IEC 61010-1 standards under following conditions
(for example):
• Rated isolation voltage: 600 V
• Reinforced isolation
• Over voltage category OV III
• Pollution degree PD2
• Non-uniform field
The creepage distance and clearance of the transducer mounted on a PCB are greater than 8 mm only if the primary
circuit tracks stay out of the shaded area shown below:
070615/8
Figure 1: zone not permitted for primary tracks (to guarantee rated creepage and clearance)
LEM reserves the right to carry out modifications on its transducers, in order to improve them, without prior notice.
