Trumeter APM-PWR-APO, 3 Phase LCD Energy Meter, 68mm Cutout Height

The Trumeter APM‑PWR‑APO is a panel‑mounted LCD meter engineered for 3‑phase energy monitoring with a standard 68 × 68 mm cut‑out. It supports line‑to‑line voltages up to 600 V, accepts a wide supply range of 100‑277 V AC, and features Modbus RTU communication, 1 % accuracy, dual digital outputs, and one analogue 4‑20 mA output. Its wide voltage input range supports direct connection or PT/CT‑based measurement configurations, while built‑in Alarms and Modbus communication enable real‑time system diagnostics and data logging.

Salient Features and Benefits of the Trumeter APM 3 Phase LCD Energy Meter

• Universal network capability (1P2W, 3P3W, 3P4W) for flexible system integration.
• Programmable PT and CT ratios to match measurement setups precisely.
• Backlit LCD display (positive type) including bar‑graph and alarm colour change.
• Rapid panel‑cut‑out size 68 × 68mm for simple retrofit or OEM mounting.
• Communication and output flexibility with Modbus RTU, two opto‑isolated digital outputs and one analogue 4‑20 mA output.
• Accuracy of 1 % (THD ≤5 %) for dependable energy and power‑quality data.

Engineered for Industrial Power Monitoring

This meter is constructed to serve demanding measurement tasks across industrial, commercial, and utility installations. The rugged 68 × 68 mm panel module, IP65 front rating and low‑profile design make it suitable for switchboards, control cabinets and retrofit environments.

Application Versatility of the Meter

• 3‑phase power and energy monitoring in industrial switchboards and distribution panels.
• Retrofit applications in OEM equipment.
• Integration into energy‑management systems via Modbus for data acquisition.
• Monitoring of voltage, current, power factor, frequency and THD in commercial installations.
• Use in critical infrastructure.
