| module HH-S7755 |
Function Features
★
Digital
chip,wide measuring range
★ Good
in accuracy and linearity, needn't turn down
current
★
It's
easy for repairing,adjusting and producing. needn't
change resistance
★
It is absolutely isolated between analog and digital
★
The ability to resist disturbance is strong. it can
effectively preventing magnetic disturbances
★
It has been considered from lots of EMC(electromagnetic
compatibility), so that it can pass the test
★ Long
life time, low probability of failure
★ Ensure
first-time pass rate of the product reach 99% at least, and provide module on approval for
one year
★
Configuration can be chosen, provide the best
cost-performance product
★ To gurantee the quality,
components are faithfully selected by the protocol,and the key components are adopted from
high-quality import brands
★
Accumulative
total of output is more than 2,000,000. production is nearly 100,000 each month
