Diversified Electronics 800.727.5646 atcdiversified.com MOTOR PROTECTION MPA2 Series Diversified Electronics 800.727.5646 atcdiversified.com Motor Protection Analyzer MPA2 is a micro-controlled based three-phase Motor Protec- tion Analyzer Relay specifically designed to protect electric loads and motors from failure and damage due to common current and voltage faults. MPA2 constantly supervises current and voltage values. When any harmful condition occurs, the output connection is deactivated until the fault disappears, power line conditions return to an acceptable level and the motor has been totally cooled. Specific timing such as Start Up Delay (TC) and Trip Delay (TD) are incorporated to prevent nuisance tripping due to rapid power fluctuations. MPA2 provides LCD Display to indicate the output status voltage, current, unbalance, frequency and load status and failure conditions. It also provides four (4) push buttons (1 for START, 2 for ADJUST and 1 for SELECT) for operation and protection parameters adjustment. Besides these mentioned advantages, a Communication Port with MODBUS RTU proto- col is included with MPA2. An innovative mechanical design allows two (2) placement options:
- Symmetrical Din-Rail mounting.
- Flat Surface mounting, using an exclusive attachable mounting ear. MPA2 has been developed using the most advanced technol- ogy and designed in accordance with the IEEE, IEC and NEMA protection standards and developed in compliance with IEC electromagnetic compatibility standards, working safely under the hardest electrical environments. When you use a MPA2 Motor Protection Analyzer, you are working with the best solution to protect your most impor- tant investments. MEASUREMENT OF:
