The UNI-T UT261B identifies 3-phase sequence and motor rotation direction without physical terminal contact. It operates between 90V and 600V AC within a 15Hz to 400Hz frequency range. This model upgrades the predecessor UT261A by adding non-contact magnetic field detection for motor spin.
Key Features
- Non-contact Motor Testing: Detects spin direction via magnetic field without physical terminal connection. Identifies rotation on sealed industrial motors.
- LED Phase Indication: Three separate light signals show L1, L2, and L3 status. Prevents phase-reversal damage in 3-phase systems.
- 2-Meter Drop Proof: Ruggedized housing withstands impact from falls up to two meters. Protects internal circuitry against accidental drops.
- CAT III 600V Safety: Meets high-voltage protection standards for fixed industrial installations. Protects users during high-load electrical diagnostics.
- 90-600V Range: Supports standard to industrial AC voltage levels. Operates across various power grids in Bangladesh.
