Built-in overcurrent detection (OCD) units separate the control appli-
cation path to the safety loop. With two separate OCD units, the sensor
can monitor overload and short-circuit events simultaneously.
The protection and detection features of the MSR series target
AC or motor-driven applications. For solar-industry applications,
which need to be surge-tolerant to provide adequate lightning protec-
tion, LEM has designed and tested the MSR to deliver the required
performance per the standard 20- s surge test profi le.
LEM provides an MSR evaluation board for quick prototyping and
test (Figure 4).
