VT3-OL Series AC Voltage Transducer
The VT3-OL Series Voltage AC Transducers are high-performance, True RMS transducers designed for accurate voltage sensing in three-phase applications. Housed in a DIN rail or panel mount case, the VT3-OL Series Voltage AC Transducer monitors common three-phase voltage ranges (120, 240, and 480 VAC) up to 600 VAC and includes Phase Loss Detection with an SPST Form A relay.
Available in 3-wire (Line-Line) or 4-wire (Line-Neutral) voltage configurations, it provides industry-standard analog outputs proportional to the connected voltage.
The VT3-OL is powered by 120 VAC. Consider the VT3-OS if you are looking for a 24 VAC/VDC powered solution. Explore our VT3 Selection & Application Guide to find the perfect fit for your needs.
TRUE RMS VOLTAGE MONITORING
- Detect below normal or “brownout” voltage conditions to prevent motor overheating.
MONITOR 3-PHASE VOLTAGE INPUTS
- Ideal for challenging electrical environments and non-sinusoidal power applications like VFDs.
INDUSTRY STANDARD OUTPUT OPTIONS
- 4-20 mA, 0-5 or 0-10 VDC.
PHASE LOSS DETECTION
- SPST Form A relay activates when voltage drops below threshold.
EXTERNALLY POWERED
- Externally powered (120 VAC) with low consumption. Consider the VT3-OS for 24 VAC/VDC applications.
FLEXIBLE MOUNT OPTIONS
- DIN Rail or Panel Mount.
UL/cUL LISTED, CE CERTIFIED
- Accepted worldwide
