Carrier P251-0091

Totaline® - P251-0091 - 3 Phase Monitor

Totaline® - P251-0091 Programmable 3-Phase Voltage Monitor

The P251-0091 was specifically designed to protect motors and other 3-phase loads from premature failure and damage due to common voltage faults such as voltage unbalance, over/under voltage, phase loss, reversal, incorrect sequencing and rapid short cycling.

Features:

• Reliable LCD Display - simplifies system setup and diagnostics Indicates condition of incoming line voltage, fault conditions, system setpoints and other user adjustments
• Temperature: -3 to +1 67°F (-20 to +75°C).
• Simultaneous voltage display - view all 3 phases at once--no need to scroll through readouts
• Fully adjustable variables - user may easily set and adjust variables when in SETUP mode:

  + Line Voltage (190-600 VAC) + Voltage Unbalance (2-20%) + Delay on Break period (0-10 min.) + Fault Interrogation (0-15 sec ) + Over/Under Voltage (2-25%) + Reset Modes (AUTO or 0-10) + Control Modes: ON or OFF * Easy to install and configure - wiring diagram on unit, simple 7-step push button setup, guide included. * 25-Fault memory storage - clearly displayed in LCD. * Ultra bright LED indicators - shows current mode:

  + Set-Up LED + Load Energized LED + Control Voltage LED + Front Fault LED
