2P Smart Voltage Protector Type M Five Digital Displays

Modern energy management and automatic control systems require real-time, multi-dimensional power data support and precise fault protection. Different from traditional single-function protection relays, PUGAO (Mora) 2P Smart Voltage Protector Type M Five Digital Displays adopts industrial 32-bit DSP high-speed processing core, which can realize high-precision sampling and analysis of multiple electrical parameters. It supports independent threshold setting of overvoltage,overload and power quality anomalies and helps enterprises optimize power consumption and improve power supply reliability.

Why Install Multiple External Sub-Meters?

Core Product Advantages

• Full-Parameter Synchronous Display: Covers real-time voltage (V), working current (A), active power (kW), power factor (PF) and cumulative energy consumption (kWh), realizing one-screen full grasp of circuit operating status.

• Integrated Replacement Design: One machine replaces multiple external sub-meters and current transformers, optimizing cabinet layout, reducing wiring complexity, and supporting real-time discovery of harmonic anomalies and reactive power loss problems.

Are You Getting Penalties for Poor Power Factor? Complete Quality & Overload Protection

Beyond standard voltage tracking, the smart platform includes integrated monitoring for active power overloads and power factor drops. If a connected machine begins to fail and draws excessive wattage or drops its power factor, the controller identifies the issue and executes a safe shutdown before the problem can damage the wider sub-panel. Standardizing on the 2P Smart Voltage Protector Type M Five Digital Displays helps facilities maintain clean power quality and avoid utility penalties for poor power factor performance.

Non-Volatile Energy Log and Accumulated Data Retention

The accumulated energy usage data (kWh) is written directly to an onboard non-volatile memory chip that stores information independently of main grid power. This data log maintains its records through extended blackouts or system shutdowns without needing an internal battery. This persistent memory allows facility managers to maintain accurate, long-term records of equipment energy consumption for cost allocation and efficiency audits.

Precision Fault Identification: 2P Smart Voltage Protector Type M Five Digital Displays can capture subtle power quality changes such as power factor drift and harmonic fluctuation that cannot be identified by ordinary single-chip microcomputers. It accurately distinguishes normal switching transient signals and real fault anomalies, ensuring no missing protection and no nuisance trips.

Product-Specific Technical FAQ

Q: Can the accumulated energy usage readout (kWh) be reset back to zero when relocating the module to a new machine circuit?

A: Yes, the accumulated energy log can be cleared and reset to zero by pressing and holding a designated combination of faceplate programming keys for 5 seconds. This function allows users to reset the tracking data when moving the 2P Smart Voltage Protector Type M Five Digital Displays to monitor a different machine or start a new billing cycle.

Q: Why is the power factor (PF) window showing a low value like 0.65 even though the line voltage is perfectly stable?

A: A low power factor is caused by inductive downstream loads, such as large electric motors or older HVAC compressors, which create a phase shift between voltage and current. This reading indicates a load efficiency issue rather than a fault with the 2P Smart Voltage Protector Type M Five Digital Displays, helping maintenance teams identify where power factor correction capacitors may be needed.

Q: How does the active power protection feature protect industrial motors from damage during a mechanical jam?

A: When a pump or conveyor belt jams mechanically, the motor stalls and draws excessive electrical power (kW) to try to turn. The high-speed processor inside the product detects this sudden wattage spike instantly and opens the relay within milliseconds, protecting the motor windings from overheating and burning out.
