800.727.5646 atcdiversified.com Diversified Electronics MPA Series Phase Voltage Monitors // MPA Series 211 Mo t o r P e r f o r ma n c e A n a l y z er The MotorGuardianTM is a microprocessor based overload relay is 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 can accommodate up to 1500 ampere loads. There are two separate models that cover two input voltage ranges. The Model MPA-1000 has a direct input voltage range of 200-500 VAC, 3-phase. The MPA-1100 has been designed to accept secondary volts from medium voltage transformers and has an input range of 120-240VAC, 3-phase.
