Megger LT300 High Current Loop Tester
A high current loop tester that is ideal for industrial applications with 50 V to 500 V and 16 Hz to 400 Hz operational range. Megger LT300 offers users the assurance of a CAT IV rating.
Housed in a rubber armoured case with a built-in cover to protect the display when not in use. The IP54 weatherproof rating provides excellent protection in adverse conditions. It has a large clear display that aids visibility in poor conditions.
The LT300 offers high current loop testing over a wide range of frequencies and supply voltages with simple, fast, two wire operation.
The high current loop test provides fast accurate and stable results with a resolution to 0.01 Ω on the 20 Ω range.
Frequency range: Supply frequency is indicated upon connection to the supply. This will automatically set to the measured supply frequency either 16 Hz, 50/60 Hz or 400 Hz. Testing will commence automatically.
Loop Impedance measurement:
- Two loop impedance ranges are provided
- 20 Ω - Resolution to 0.01 Ω
- 200 Ω - Resolution to 0.1 Ω
Supply voltage: Operational supply range extends from 50 V to 550 V (400 V @ 16 Hz), with a warning for voltages over 330 V highlighting accidental phase to phase connections on a nominal 230 V system.Single Phase CATIV 300 V phase to earth, as well as 550 V phase to phase applications (400 V @ 16 Hz).
