ATC Diversified PBC-230-ALE 275 VAC Phase Voltage Monitor

Features:

• The PBC Series offers protection to three-phase equipment that is required to operate between two voltage limits.
• All three phases are monitored individually for a pre-selected Under and OVER VOLTAGE limit.

Operation

With normal operating voltages applied, the internal relay will energize (PICK-UP). When the voltages on any or all phases fall outside the pre-set Over/Under trip points for longer than the Release delay, the relay will de-energize (DROP-OUT). When line conditions return to normal, the PBC Series Monitor automatically resets and the internal relay energizes. The LED fault indicators aid in setup and system trouble-shooting glowing on fault condition. The LED indicators have an immediate response to voltage conditions and operate independently of the relay. The HYSTERESIS in each unit provides a differential of 4% between the PICK-UP and DROP-OUT trip points.
