Thiết bị phân tích công suất điện cố định  Circutor CVM-MINI-MC-ITF-RS485-C2, Power analyzer  Code: M52081. 

DESCRIPTION

Three-phase power analyzer (balanced and unbalanced), assembly on DIN rail, with a very compact size, and 4-quadrant measurement.

Other features include:
 

• Current measurement .../5 or .../1 A or .../250 mA, .../333 mV
• DIN rail format of only 3 modules
• Assembly on 72 x 72 mm panel with adapter front panel
• RS-485 Communications (Modbus-RTU) depending on model
• It features two transistor outputs (programmable)
• With ITF technology: galvanic insulation protection, depending on the type
• Selection of parameters to display
• Selection of the default page
• Universal power supply (optional)
• Sealable

APPLICATIONS

• Control application on switchboards and low and medium voltage connection points, where an analyzer must be installed on a DIN rail due to space restrictions.
• Alarm control. Maximum value, minimum value and programmable delay.
• Control of active or reactive energy using the impulse output.
• Instantaneous data capture, maximum and minimum values of the electrical parameters measured.
