Voltage Detection
A voltage detector, also known as a voltage tester or test light, is an electronic testing device used to determine the presence of electricity in a conductor.

Voltage detectors can be both handheld or built into a circuit, depending on application requirement. Handheld detectors often resemble pens or flashlights, and are usually used for routine testing where efficiency is valued. Permanent detectors are hardwired into a control circuit and are used for safety purposes. If a machine is still drawing power when it shouldn't be, for example, an inline detector can indicate this to operators.

Built-in detectors offer the most flexibility, in the voltage threshold required for detection, the maximum voltage the equipment can measure, and their integration into control systems like how far away from a machine they can be.

VS-AVT Series Image
  • Indicator Module
  • AVT System Cable
  • Isolation Module
  • Sensor Leads
The VS-AVT minimizes risk by verifying the absence of voltage before equipment is accessed, making it easier for qualified electrical workers to determine an electrically safe environment in a fraction of the time compared to hand-held portable test instruments.
UPA-100 Series Image
  • Detects Single or 3-Phase AC & DC Voltage or Stored Energy
  • Redundant Circuitry
  • Verification of Zero Energy in a Panel
  • Fits 1-1/4" Conduit Knock-Out
UPA-130 Series Image
• Verification of Stored Energy Inside A Panel
• Fits 30mm Knockout
• Redundant Circuitry
The UPA 130 Power Alert reduces the risk of electrical arc flash by pre-verifying the electrical isolation from outside of a control panel. Hard wired to the circuit breaker or main disconnect, the UPA flashes whenever voltage is present. Engineered with redundant circuitry, the Power Alert is powered by the same voltage that it indicates.

  • Enhances NFPA 70E & OSHA Compliance
  • Reduces Arc Flash & Electrocution Risk
  • Detects Stored Energy
  • Detects Ground Fault Problems
  • No Voltage Present on Enclosure Door Panels
  • DIN Rail or Surface Mounted Base
