Phase Rotation Testers

PSI4000 Phase Rotation Indicator The Martindale PSI4000 is a unique phase rotation indicator that carries out the measurement via inductive crocodile clips. This method increases the safety of the user, whilst the bright LEDs give a clear indication of either clockwise or anti-clockwise phase rotation.The design of this phase rotation tester allows for use on both insulated or uninsulated conductors, and an "Enhanced Brightness" switch makes indication brighter in strong ambient light. A combination of both rotating LEDs and buzzer tones indicate clockwise or anti-clockwise rotation Input Voltage: 150V-1000V 3-Phase AC.Frequency Range: 45-65HzOperating Temperature & Humidity: -10 °C to 50 °C, Max. 80%RH.Battery Current consumption: 15mACable Length: Approx. 800 mmPower Source: 1.5V X 4 (AA or LR6) alkaline batteriesAuto-Off: After 5 mins of non activityLow Battery Warning: Power LED flashes below 4.6V DC battery voltage Supplied with 4 x AA batteries, soft carry case and instruction manual Martindale Phase Sequence Indicator The Martindale phase sequence indicator works on a principle of static induction with voltage rating ranges between 150V and 1000V AC (phase to earth). It includes 4xAA batteries, a soft carry case and instruction manual. This indicator measures inductive crocodile clips. This method increases the safety of the user, whilst the bright LEDs give a clear indication of either clockwise or anti-clockwise phase rotation. Supplied with 4 x AA batteries, soft carry case and instruction manual Features and Benefits • Bright LED and buzzer indication of live phases and sequence • Class II, double insulation • High-quality colour coded clips • Input frequency ranges between 45Hz and 65Hz • Non-contact for improved safety and ease of use • Operating temperature ranges between -10°C and 50°C • Positiv...
