Martindale Phase Rotation Tester 45 Hz to 65 Hz Frequency Range, 150V to 1000V AC Max Voltage PSI4000

Martindale PSI4000 Phase Rotation Tester is designed for precise detection of phase sequence in electrical systems. It supports an AC voltage range between 150V and 1000V (phase to earth) with input frequencies from 45 Hz to 65 Hz. The tester operates using four AA batteries and comes with a soft carry case along with an instruction manual for ease of use and portability.

This device functions on static induction principles and utilizes inductive crocodile clips, which enhances user safety by enabling non-contact voltage measurements. The bright LEDs and buzzer provide clear indications of phase rotation direction, whether clockwise or anti-clockwise, making it suitable for electrical drive applications, motor installations, and general electrical safety testing.

The PSI4000 features class II double insulation for maximum user protection, and its durable color-coded crocodile clips ensure reliability in connection. It is rated for operation in ambient temperatures ranging from -10°C up to 50°C, making it appropriate for varying industrial and commercial environments.

Compactly sized at 118mm length, 69mm width, and 38mm height with a lightweight of 370 grams, this phase sequence indicator is user-friendly and easily portable. Its maximum voltage capacity of 1000V AC and input frequencies between 45 Hz and 65 Hz cover most common industrial standards.
