Lovato DCRM2 - REATIVE CURRENT CONTROLLER RELAY - DCRM SERIES - SINGLE AND THREE-PHASE LOW-VOLTAGE SYSTEM - 2 STEPS

General characteristics

The DCRM allows the reactive current of a system to be controlled.
It can correct to the best cos value possible, reducing the request for reactive current from the mains.
It can control the connection of two capacitor banks.
Each one can be individually enabled and its power can be set through a dedicated trimmer.
It is also possible to adjust the time for connection and disconnection of the capacitors, thereby modifying the reaction speed of the system.
The controller can be used both in three- and singlephase wiring.

Operational characteristics

– Auxiliary supply voltage:
• 380...415VAC standard
• 220...240VAC and 440...480VAC on request
– Rated frequency: 50/60Hz
– 80...528VAC voltage measurement input
– Current measurement input:
• By CT /5A
• Measuring range: 0.1...6A
• Measurement type: true root mean square (TRMS)
• Automatic identification of CT connection polarity (straight / inverted)
– Relay outputs:
• 2 relays (steps), each with 1 changeover contact
• Rated current: 8A 250VAC (AC1)
• Individual enablement of control of the two relays
– Modular DIN 43880 housing (3 modules)
– IEC degree of protection: IP40 on front (if placed in IP40 housing and/or electrical panel), IP20 terminals.
