- Key Products/Technologies
- Over Load Limiter: The BFL-250D model is a Korea Occupational Safety and Health Agency certified product, specifically designed for wound rotor cranes. It features a built-in operation signal discrimination circuit for the crane's secondary resistor, enabling automatic operation based on secondary short-circuit contact signals. It supports 1 to 5 stages of speed control input signals and individual current setting capabilities for each stage. The device is waterproof, dustproof, and moisture-proof, with an automatic discrimination circuit for single-phase, phase loss, and unbalance in secondary short-circuit magnet damage. During crane startup, it automatically indicates motor voltage, current, and hoisting height in time units, providing convenient and accurate values to operators. It offers a wide application range with an operating power of AC 85V~260V dual-use and automatic current usage limits from 0.01A~1000A. It can also be installed in inverter-controlled cranes, offering an alternative for frequency fluctuations. The BFL-210D model is a KOSHA-certified product specifically for hoists, digitally indicating motor current values during HOIST CRANE operation. It incorporates a safety circuit that stops crane operation if the operator arbitrarily disconnects the control power. It boasts a current resolution capability from a minimum of 0.01A to 999A and a voltage fluctuation automatic compensation function to prevent malfunctions. The design ensures safety by automatically returning to the original height after an overload operation. It offers convenience with 1-stage operation and 2-stage (low-speed/high-speed) control functions, easily adaptable to different hoist types. User-friendliness is enhanced by allowing data settings with just three buttons. The outer casing is made of special PC material, highly resistant to external impact, ensuring strong durability.Over Load Limiter: The BFL-250D model is a Korea Occupational Safety and Health Agency certified product, specifically designed for wound rotor cranes.

- AC MOTOR SOFT START (Power Com): A product designed to perfectly control mechanical and electrical problems occurring during AC motor startup. It resolves various issues such as large inrush currents exceeding 600% during initial motor startup, belt slip, gearbox damage, water hammer phenomena in pump piping, severe shaking during conveyor startup and shutdown, and motor insulation breakdown. It is an optimal solution that controls motor starting torque and inrush current, enabling smooth motor startup and shutdown, and resolving electrical and mechanical issues. Features a robust design for 600% rated load for 50 seconds, mechanical shock absorption, inrush current mitigation, water hammer elimination, and protection for motors and mechanical equipment. Provides various startup and shutdown control functions including SOFT START, KICK START, SOFT STOP, SLOW START, CURRENT LIMIT, and SLOW STOP. Available in BD-SS30BP-S (unidirectional) and BD-SS30BP-M (unidirectional) models. The soft start control panel offers various models from 15KW (20HP) to 95KW (130HP), with custom production available for over 130HP. Comprehensive protection functions include overcurrent protection (EOCR function), phase loss detection, SCR short-circuit protection, and unbalance detection during operation. Benefits include AC starting current limiting, mechanical shock reduction, inrush current alleviation, and extended motor life. In case of an error during operation, it automatically trips the primary circuit breaker, and displays and controls the actual motor load current in real-time.AC MOTOR SOFT START (Power Com): A product designed to perfectly control mechanical and electrical problems occurring during AC motor startup.
