Technical SpecificationsModel:0-49040-2 Brand:RELIANCE Product type:Control Rectifier Card Weight:0.68kg Dimension:231mm161mm28mm Operating temperature:0℃ ~ 60℃ Storage temperature:-40℃ ~ +85℃ Relative humidity:5%~85%,non-condensing Certification:CE

System compatibility0-49040-2 belongs to RELIANCE CardPak series control rectifier card. Installed into CardPak rack,works with trigger driver board and current feedback board. It controls the thyristor rectifier power unit of CardPak DC drive system. Commonly used for old industrial DC drive equipment maintenance and spare replacement.

Function0-49040-2 is dedicated rectifier control board for RELIANCE CardPak DC drive system. Receive speed error signal from analog control board. Calculate firing angle for SCR rectifier unit. Output phase-shift trigger command to pulse driver module. Regulate DC output voltage to stabilize motor speed. Synchronize trigger pulse with AC line input. Protect rectifier stack from abnormal voltage and current impact.

InstallationPower off the whole drive cabinet and cut main power supply. Insert 0-49040-2 board into designated CardPak slot and lock retaining latch. Connect backplane bus connector and power synchronization signal wiring. Separate low voltage control wiring from high power main circuit cable. Power on system,calibrate phase synchronization and firing angle range. Test voltage adjustment performance under no-load and load condition.

InterfaceBackplane bus connector,AC sync signal input,firing pulse output terminal,analog control signal input,status LED indicators.

FeatureRELIANCE 0-49040-2,CardPak rack mount control rectifier card. Phase angle calculation and SCR rectifier triggering control. AC line synchronization circuit for stable pulse output. Closed-loop voltage regulation for DC drive. Hardware interlock protection for rectifier power section. Industrial PCB design for long continuous running in harsh factory environment. Discontinued obsolete board,supply only for old CardPak DC drive system spare replacement. Suitable for metallurgy,paper-making production line DC drive renovation and maintenance.

DiagnosticDC output voltage unstable:AC sync signal loss or phase drift; Cannot adjust output voltage:firing angle calculation circuit fault; No pulse output to SCR:trigger command circuit damage; Drive cannot reach rated speed:calibration offset of firing range; Random drive shutdown:backplane connector poor contact.

Product BriefRELIANCE 0-49040-2 is CardPak control rectifier card. It realizes phase control and SCR triggering for the thyristor rectifier unit of Reliance CardPak DC drive,widely used as spare part for legacy DC drive equipment maintenance.
