Technical Parameter
The Low Voltage Rail Transfer Cart belongs to our DDG series and is powered by low-voltage rails to drive the cart. There are two types of low-voltage rail power supply: two-phase and three-phase, depending on the power configuration available at the customer’s facility.
Two‑Phase Power Principle
Two-phase power is fed into a transformer and stepped down to a safe 36V voltage. This power is transmitted to the rails. Current collectors mounted at the bottom of the cart draw power from the rails, which is then converted to DC power via a rectifier before entering the electrical cabinet to drive the cart.
Three‑Phase Power Principle
Three-phase power goes through a transformer to be reduced to 36V and supplied to the rails. The current collectors collect power from the rails, which is then boosted by a step-up transformer and sent to the electrical cabinet to operate the cart.
Both two-phase and three-phase systems offer the same key advantages:
Continuous power supply enables 24-hour non-stop operation.
High guidance accuracy with no deviation from the rail system.
Excellent positioning precision, compatible with PLC control for unmanned automatic operation.
Low maintenance requirements with no extra upkeep needed.
Lower long-term cost compared to battery-powered transfer carts, eliminating the need for battery replacement every three years.
