MACROMATIC PMPU-FA8 3-Phase Line Monitor, Voltage Sense, 208-480VAC

Macromatic PMPU-FA8 3-phase line monitor is used in manufacturing plants, refineries, data centres, wastewater treatment facilities and food processing factories. It ensures proper phase sequence, voltage stability and fault detection, safeguarding equipment and preventing downtime due to electrical anomalies.

Working Mechanism:

• The monitor continuously monitors voltage levels in each phase.
• It then identifies voltage imbalances between phases and monitors the line frequency.
• Then the alarm is triggered or signals are controlled upon detecting abnormal conditions like imbalances, voltage issues or frequency deviations.
• This protects motors and equipment by preventing operation under unfavourable electrical conditions.

Features:

• It has a socket mounting style and utilises a socket for enhanced electrical connection.
• It can handle an input voltage range of 190 to 500VAC.
• It can monitor overvoltage fixed at 110 percent of line voltage setting, undervoltage operating at range of 190 to 500VAC and phase reversal with a time delay.
• It has a maximum switching capacity of 40VA and consumes 40VA of power.
• It supports automatic and manual restart with a restart time delay of 2 seconds.

Standards and Approvals:

• cULus
• UL
• CE
