Phase Loss Protection

Voltage Transducer Applications

True RMS Voltage Monitoring

• Detect below normal or “brown out” voltage conditions; protect against possible motor overheating.
• Identify phase loss conditions by detecting voltage reduction in one or more phase of three-phase motor.
• Monitor over voltage conditions associated with regenerative voltage to help in diagnosing/avoiding motor drive issues.
• Detect voltage conditions which may cause stress in or damage to soft starter components (SCRs).

Voltage Transducer Features

True RMS Output

• Allows for use in situations where power supplied is poor power quality or other electrically harsh/challenging environments.

Standard 4-20 mA Loop-powered Output

• Industry standard output makes use with existing controllers, data loggers and SCADA equipment easy and reliable.

Input/Output Isolation

• Input and output circuitry electrically isolated for improved safety of use.

Compact DIN Rail Mounted Case*

• Space saving 35 mm wide enclosure mounts quickly for an attractive installation.

UL/cUL and CE Approved

• Accepted worldwide.
