Power Alerts

UPA 100

The UPA-100 Power Alert 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 flashes whenever voltage is present. Engineered with redundant circuitry, the Power Alert is powered by the same voltage that it indicates. 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).

UPA 130

The UPA 130 Power Alert 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 flashes whenever voltage is present. Engineered with redundant circuitry, the Power Alert is powered by the same voltage that it indicates. The eight detector UPA-130 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).

UPA 130S

The UPA 130S Power Alert 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 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).

UPA 130 DIV 2

The UPA 13 0DIV 2is Class 3, Division 2 FM approved for use in hazardous environments. The UPA 130 DIV2 Power Alert 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 flashes whenever voltage is present. Engineered with redundant circuitry, the Power Alert is powered by the same voltage that it indicates. The eight detector UPA-130 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).

BFA Series

With nominal 3-phase line voltage applied, a flashing green NORMAL LED gives positive indication of a good fuse and integrity of the wire connection to each side of the fuse. A flashing red FAULT LED gives positive indication of an unconnected or open fuse, or a BFA wiring fault that needs corrected such as a lost connection to either side of the fuse or mismatched line and load wires. When phase loss occurs, both FAULT and NORMAL LEDS will extinguish. The BFA will continue to indicate the status of the fuse during a phase loss if a regenerated voltage is produced on the open phase from a rotating motor.

GFD Series

The ATC Diversified Electronics GFD Series is intended for the use on ungrounded systems to detect and indicate the phase of the first ground fault condition. This enables corrective action to avoid the potential hazards resulting from a second ground fault. With nominal 3 phase line voltage applied, a flashing NORMAL green LED gives indication of a non-fault condition and integrity of the wire connection to the corresponding phase. A flashing red LED gives positive FAULT indication of either a phase-to-ground fault, or a lost connection to the corresponding phase.
