Universal Phase Monitor Phase Monitor Relays (3-Phase Monitors) provide cost-effective protection against premature equipment failure caused by voltage faults on 3-Phase systems (Wye or Delta). The SLU Series multi-mode phase monitoring relay, was designed for the convenience of electrician's, maintenance managers and engineers. A single SLU Phase Monitoring Relay can be easily adjusted for the voltage, imbalance percentage and time delay requirements to protect against unbalanced voltages or single phasing regardless of any regenerative voltages. Both DELTA and WYE systems may be...

The ATC-Diversified Electronics SLU-600-ASTDS Universal Phase Monitor protects 3-phase motors up to 700VAC. The Rapid Cycling feature prevents motors cycling due to load-induced line fault conditions. Powered by 120VAC, this reliable motor protection relay is unaffected by transients and disturbances from the monitored power source. The SLU-600 Series is UL Listed under UL File Number E55826. specifications AUTO RANGING SCALES Drop-out Pick-up Universal Phase Monitor ±10% of Range Setting (Under/Over) ±7% of Range Setting (Under/Over) CONTROL VOLTAGE 120 VAC ±10%, 50/60Hz 700 VAC...

The MotorGuardianTM is a microprocessor based overload relay designed to provide protection for 3-Phase AC motors. It offers a broad range of features in one compact package providing a cost effective solution for monitoring and managing motor performance. Actual motor operating conditions are accessed by the scrolling menu and viewed by a two line highly visible vacuum fluorescent display. Fault conditions are also displayed indicating the specific cause of the occurring fault. A unique feature of the The MotorGuardianTM is its ease of installation. It is provided with Clamp-On C.T.'s that...

The MGR Remote Manager is a component of the MotorGuardian family that is used in conjunction with the Motor Performance Analyzer (MPA ). It provides full control and monitoring of the MPA functions by mimicking the keypad and display. The front panel programming is identical to the MPA that simplifies the learning process. This external control provides an efficient and safe tool away from potentially dangerous voltages. The MGR is environmentally protected (NEMA 4X) and is easily mounted using a cutout on the front of a control panel or MCC. A vacuum fluorescent display (VFD) was selected...

The PRA-100 Series Phase Sequence Monitors are designed to allow the output to energize only when the phase connections are in the proper sequence. For use in applications where motor direction is critical or the installation is required by code to have sequence detection. When the phase sequence is correct and the operating voltage is present on all phases, the relay will energize and the green LED indicator will glow. If the phases are in reverse rotation, the relay will not energize and the red LED indicator will glow. The PRA-100 Series will not detect phase loss while the motor is...

With normal operating voltages applied in the proper ABC sequence, the internal relay will energize (PICK-UP). When incorrect phase sequence or phase loss occurs or the three-phase voltages fall below the drop out voltages, the relay will de-energize (DROP-OUT). On models featuring indicators, the LED glows when all line conditions are normal. The ATC Diversified SLA Series is designed to protect 3-phase equipment against PHASE LOSS, UNDER VOLTAGE, and PHASE REVERSAL conditions. Both Delta and Wye systems may be monitored. In Wye systems, connections to neutral are NOT required. NOTE: When...

The PBC Series offers protection to three-phase equipment that is required to operate between two voltage limits. All three phases are monitored individually for a pre-selected under and over voltage limit. operation With normal operating voltages applied, the internal relay will energize (PICK-UP). When the voltages on any or all phases fall outside the preset Over/Under trip points for longer than the Release delay, the relay will de-energize (DROP-OUT). When line conditions return to normal, the PBC Series Monitor automatically resets and the internal relay energizes. 3-Phase Voltage...

The PBD Series offers protection to three-phase sequence sensitive equipment that is required to operate between two voltage limits. All three phases are monitored individually for a pre-selected Under and Over voltage limit, with adjustable release delay. operation With normal operating voltages applied in the proper ABC sequence, the internal relay will energize (PICK-UP). When the voltages on any or all phases fall outside the preset Over/Under trip points for longer than the Adjustable Release delay, the relay will de-energize (DROPOUT).
