UPA Series Universal Power Alerts

UPA Series Universal Power Alerts

Product catalog summary

Overview: The UPA Voltage Alert is designed to enhance electrical safety by pre-verifying electrical isolation from outside an electrical panel, reducing the risk of electrical arc flash. It is hard-wired to circuit breakers or main disconnects and uses LED indicators to signal hazardous conditions.

Specifications: The device operates within a range of 40-600 VAC and 30-1000 VDC, with a maximum rated voltage of 750 VAC/1000 VDC. It is engineered with redundant circuitry and is powered by the voltage it detects. The UPA is available in three configurations and fits standard push-button and conduit knockouts.

Features: The UPA detects single or 3-phase AC and DC voltage or stored energy, verifies zero energy in a panel, and fits 1-1/4" conduit knockouts. It is ideal for Lockout/Tagout procedures, enhancing NFPA 70E and OSHA compliance, and reducing arc flash and electrocution risks. The device is encapsulated for environmental protection and can be DIN rail or surface mounted.

Operational Range and Ratings: The operational range for AC is 20-600 VAC and for DC or stored energy is 30-1000 VDC. The temperature rating for operation is -4° to 131°F (-20° to +55°C) and for storage is -40° to 185°F (-40° to +85°C). Power consumption is approximately 1.2 Watts at 750 VAC.

Indicator Flash Rates: The device provides visual alerts with flash rates varying based on voltage levels, ensuring compliance with epileptic photosensitivity standards.

Models and Accessories: The UPA series includes models UPA-100, UPA-130, and UPA-200, each with specific features and configurations. Accessories include ANSI warning plates and bezel kits for various mounting options.

Compliance and Safety: The UPA devices support compliance with OSHA 1910.147 for the control of hazardous energy, ensuring that all potentially hazardous stored or residual energy is rendered safe before maintenance or servicing.

Indicating Zero Energy VOLTAGE PRESENT WHEN FLASHING SAFETY PROCEDURES STILL APPLYI VOLTAGE PRESENT WHEN FLASHING SAFETY PROCEDURES STILL APPLYI The UPA Voltage Alert reduces the risk of electrical arc flash by pre-verifying the electrical isolation from outside of an electrical panel. Hard wired to the circuit breaker or main disconnect, the UPA LED's flash or illuminate (depending on model) to indicate the presence of hazardous conditions, 40-600 VAC & 30-1000 VDC, associated with stored energy. Engineered with fully encapsulated redundant circuitry, the Voltage Alert is powered by the same voltage that it indicates. Available in 3 configurations, the easy to install UPAs fit through standard push-button

• Detects Single or 3-Phase AC & DC Voltage or Stored Energy • Redundant Circuitry The eight detector UPA-100 visually alerts to the presence of dangerous AC or DC (Stored Energy) potentials occurring between any combination of the four monitored input lines (L1, L2, L3, GND). Two LED indicators are assigned to each input line and are designated “+” and “-”. For each input line carrying an AC potential (bi-polar), both the “+” and “–” LEDs will be active. A DC or Stored Energy potential will illuminate the “+” LED for the positive line and the “–” LED for the negative line. • Verification of...

OSHA 1910.147 THE CONTROL OF HAZARDOUS ENERGY (LOCKOUT/TAGOUT) ORDERING INFORMATION Following the application of lockout or tagout devices to energy isolating devices, all potentially hazardous stored or residual energy shall be relieved, disconnected, restrained, and otherwise rendered safe. (d)(5)(ii) If there is a possibility of reaccumulation of stored energy to a hazardous level, verification of isolation shall be continued until the servicing or maintenance is completed, or until the possibility of such accumulation no longer exists. (d)(6) “Verification of Isolation.” Prior to starting...
