Mastech MS5900 Phase Rotation Indicator

Description

The Mastech MS5900 is a motor and phase rotation indicator, not a multi-function circuit analyzer like some other devices in the Mastech MS5900 series. It is a specialized, battery-operated instrument designed for electrical professionals to check the phase sequence of three-phase systems and the rotation direction of motors.

Key Features

• Tests three-phase systems: The device features three indicator lights (L1, L2, L3) and test leads for detecting the phase sequence of three-phase power.
• Determines motor rotation: It can determine the rotary field direction (clockwise or counter-clockwise) by measuring the magnetic field of an electric motor.
• Non-contact detection: The indicator can detect a magnetic field simply by placing it against a solenoid or motor, providing non-contact detection.
• Voltage range: It can be used for rotary direction testing on systems from 1 to 400V AC and for phase indication from 120 to 400V AC.
• Frequency range: The unit can operate in a frequency range of 2 to 400 Hz.
• Safety rating: It is certified for safe use in CAT III 600V environments.
• Portability: The MS5900 features a compact and portable design, making it easy to carry and use on-site.
• Power source: It is powered by a 9V battery and comes with a carrying case and test leads.
