Product information
Overview
Applications
- Electrical variable measurement: Measures voltage, current, active power, reactive power, and frequency in stationary control panels.
Key Features
- Electrical measurement: Measures voltage, current, active power, reactive power, and frequency; voltage and current measurement use TRMS.
- Voltage measurement: Rated measurement is 400 V between (PE)N and L and 690 V between line conductors; the maximum between (PE)N and L is 480 V.
- Current measurement: Rated AC current values are 1 A and 5 A, with external current transformers supported for range extension.
- Display and operation: The 54 mm x 72 mm white LCD has adjustable contrast and 4 keys; backlight illuminance is not adjustable, but time-controlled reduction is possible.
- Communication and I/O: Uses Modbus RTU with a transfer rate of 4.8 kbit/s to 115.2 kbit/s, 2 digital inputs, and 2 bidirectional digital outputs.
- Panel installation and protection: The 96 mm x 96 mm device mounts vertically in stationary panels in closed rooms; front protection is IP65 and DIN-rail mounting is not supported.
