ATC Diversified UPA-200 Series – Power Alert

The UPA-200 Power Alert reduces the risk of electrical arc flash by pre-verifying the electrical isolation from outside of an electrical panel. Hardwired to the circuit breaker or main disconnect, the UPA LED’s flash to indicate the presence of hazardous conditions (20-600 VAC & 20-1000 VDC) associated with stored energy. Engineered with redundant circuitry, the power alert is powered by the same voltage that it indicates. The unit is easily installed into the panels through a standard push-button 33mm knockouts.

The UP-200 Series is ideal for mounting on the front controller door panel. The use of fiber-optics on this unit to transmit the LED lights to the enclosure door allows the unit to be mounted on a ungrounded door panel due to no voltage present on panel

The eight detector UPA-200 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 are designate “+” 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.
