Product overview A threephase power monitoring and control instrument designed for flexible mains and generator configurations. Clear backlit display and simple pushbutton operation provide fast, reliable readings of key electrical parameters to support power management and system troubleshooting. Key benefits Flexible system pairing: Supports all four configuration modes for mains and generator connections: Mains (1#) and Mains (2#), Mains (1#) and Generator (2#), Generator (1#) and Mains (2#), Generator (1#) and Generator (2#). Makes integration with transfer switches and dualsource systems straightforward. Clear information at a glance: Backlit 128x64 LCD presents measurement data in an easytoread format. Optional Chinese and English display makes the unit adaptable to local use. Simple operation: Pushbutton control lets technicians navigate menus and settings without specialized tools. Essential electrical measurements: Measures and displays active power, apparent power, power factor, and threephase current to support load balancing, efficiency analysis, and system optimization. Better operational decisions: Ready access to power, apparent power, and power factor helps identify inefficiencies and improve conversion rates during source switching and load changes. Important attributes Function: Realtime measurement and display of active power, apparent power, power factor, and threephase current. Compatibility: Configurable for mains and generator combinations as listed above for use in dualsource systems. Display: Backlit 128x64 LCD with optional Chinese and English language selection. Operation: Pushbutton interface for setting and reading parameters. Performance: Delivers key power metrics to assist in monitoring, diagnostics, and conversion rate improvements. Typical applications Backup power systems: Monitor mains and generator inputs at an automatic transfer switch to verify source behavior and load transfer. Industrial power management: Track active and apparent power and power factor across three phases to support load balancing, energy monitoring, and corrective action. Remote or localized control panels: Provide clear measurements in control cabinets, switchgear, or generator control enclosures where straightforward operation and language options are required. This instrument is intended for professionals who need precise, accessible electrical measurements and reliable system configuration for dualsource power applications.
