Lovato DCRL3 - AUTOMATIC POWER FACTOR CONTROLLER - DCRL SERIES - 3 STEPS

General characteristics

The DCRL series was developed with advanced functionality and produced with a dedicated ultracompact housing. It combines modern front design with practical mounting and expandability (EXP… modules).

Its main features are:
– Backlit icon LCD with excellent information display
– Alarm codes with scrolling texts, programmable in 6 languages (Italian, English, Spanish, French, German and Portuguese)
– Connection in single or three phase lines and cogeneration systems with 4-quadrant operation
– Voltage measurement input independent of supply and which can be used in medium-voltage lines with VTs
– Drastic reduction in the number of switching operations
– Balanced use of steps with same power rating
– Measurement of reactive power installed for each step
– Capacitor over-current protection
– Panel over-temperature protection via internal sensor
– Accurate micro-breaking protection
– Vast choice of measurements available, including voltage and current THD with single harmonic analysis up to the 15th order.
– Wide voltage measurement range
– High accuracy of true root mean square (TRMS) measurements
– Front optical USB (CX 01 dongle) and Wi-Fi (CX 02 dongle) communication port for PC, smartphone and tablet connection
– Compatible with Ethernet communication modules EXP10 13 (only for DCRL 8)
– Compatible with Synergy supervision and energy management software, Xpress configuration and remote control software and with the Sam1 application for Android/iOS.
– Customisation with label on front (only for DCRL 8).
