Voltage detector UPA-100

The UPA-100 Power Alert pre-verifies the electrical isolation from outside a control panel, thus reducing electrical arc flash risk. It is hardwired to the circuit breaker or main disconnect. Whenever there is voltage, UPA will flash. It is powered by the same voltage that tends to indicate and comes with a redundant circuitry. The UPA-100 Power Alert provides visual alert if there are any dangerous AC or DC (stored energy) potentials that are occurring between any of the four monitored input lines (L1, L2, L3, GND). Each input line will come with an LED indicator and is designated with a + and -. Both the + and – will be activated for each input line carrying an AC potential or bi polar while A DC or Stored Energy potential will illuminate the + LED for the positive line and the - LED for the negative line.
