100-Volt DC
Transducer Allows
for Accurate Monitoring
Tualatin Valley Labs’ ( TVL’s) new dC10 dC Voltage
Transducer is designed to convert a dC voltage
input to either a 4-20 mA or a 0-5 VdC output
that is proportional to the input. The transducer
provides effective isolation to 4. 5 kV and includes
safety ratings for both UL and CSA. dIN configuration and standard 24-VdC power allow quick and
easy installation. voltage-transducer.com
ABB Improves Arc Protector
The ABB Low Voltage Products
division has released TVOC- 2, a new
generation of its proprietary Arc
guard System. It can detect faults in
low- and medium-voltage switchgear,
and disconnect power within 30 to
50 milliseconds, preventing injury
to personnel and damage to equipment. TVOC- 2 is now UL-listed, and
when installed along with ABB’s Emax
circuit breakers, carries a functional
safety rating of SIL- 2, certified by TÜV
