System compatibility 0-49005-5 belongs to RELIANCE CardPak series linear voltage time unit board. Installed into CardPak rack,works with regulator board and power supply board. It performs closed-loop voltage regulation and timing control for CardPak DC drive system. Commonly used for old industrial DC drive equipment maintenance and spare replacement.

Function 0-49005-5 is dedicated linear voltage time unit board for RELIANCE CardPak DC drive system. Realize closed-loop voltage regulation according to feedback signal and reference setpoint. Provide adjustable ramp timing function for drive acceleration and deceleration. Two rotary potentiometers for rate parameter on-site adjustment. Respond quickly to load variation and stabilize output voltage of DC drive. Built-in overvoltage monitoring circuit and fault feedback output. Transmit regulation status signal to main regulator card.

Installation Power off the whole drive cabinet and cut main power supply. Insert 0-49005-5 board into designated CardPak slot and lock retaining latch. Connect backplane bus connector and analog signal wiring. Separate low voltage control wiring from high power main circuit cable. Power on system,adjust front panel potentiometers to set ramp rate. Test voltage regulation response under no-load and load condition.

Interface Backplane bus connector,analog signal input & output terminal,adjustment potentiometers,status LED indicators.

Feature RELIANCE 0-49005-5,CardPak rack mount linear voltage time board. High-speed closed-loop voltage regulation for DC drive. Front panel adjustable potentiometer for ramp rate setting. Built-in voltage monitoring and fault signal feedback circuit. 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.

Diagnostic 

Drive unstable voltage output:potentiometer drift or feedback signal abnormal; Slow acceleration response:rate parameter misadjustment; Voltage overshoot:linear regulation circuit aging; No regulation effect:backplane connector poor contact; System voltage alarm:internal monitoring circuit failure.
