UPA-130S Solid ON Power Alert
The UPA-130S Solid ON Power Alert from ATC Diversified Electronics reduces the risk of electrical arc flash by pre-verifying the electrical isolation from outside of a control panel. Hardwired to the circuit breaker or main disconnect, the UPA lights at a steady state whenever voltage is present. Engineered with redundant circuitry, the UPA-130S Power Alert is powered by the same voltage that it indicates.
The eight detector UPA-130S visually alerts to the presence of dangerous AC or DC (Store 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.
