Digital Multifunction Power Meter
This high-precision multifunction power meter is designed for reliable monitoring of electrical parameters in single and three-phase systems. With a wide measuring range of 100mA to 5A and compatibility with various CT ratios, it ensures accurate readings for voltage (up to 300V AC LN), current, and power metrics.
Key Features:
• Operating Voltage: 150–270V AC, 50/60Hz
• Display: Large, clear LED screen (7-segment, 4-digit) with red and green indicators
• Measuring Range: 100mA to 5A (various CT compatibility)
• Operating Temperature: -30°C to +55°C
• Connection: Plug-in terminal connection
• Mounting: Panel and DIN rail options
• IP Protection: IP21 (front panel), IP00 (body)
Key Features:
• Sensor Type: NTC for accurate temperature measurement.
• Control Output: Relay outputs for both control (heating/cooling) and alarm functions.
• Adjustable Upper/Lower Limits for both Set and Alarm values.
• Password Protection to prevent unauthorized changes.
• Displays SET and PROCESS values simultaneously.
• Adjustable Hysteresis Value and Offset settings for fine tuning.
• EEPROM memory for parameter retention even after power loss.
• Easy installation with plug-in connectors.
