Function Characteristics

  1. All-round three-phase power supply fault monitoring: phase loss, reverse phase sequence, overvoltage, undervoltage, three-phase voltage unbalance, neutral wire breakage (optional version)
  2. Full parameter mechanical knob adjustment on front panel, no need to connect upper computer software for parameter setting
  3. Adjustable action delay time, avoid false alarm caused by instantaneous power supply fluctuation
  4. Independent SPDT relay output contact, can directly drive alarm horn or contactor trip coil
  5. Multi-group LED status indicators: power supply normal, fault trigger, three-phase voltage status
  6. Optional sealable parameter adjustment cover, prevent on-site personnel random modification of protection threshold
  7. Short-circuit protection of internal sampling circuit, avoid module burnout caused by power supply wiring error
