R911251872
The R911251872 (TVM 2.4-050-220/300-W1/220/380) is a power supply module produced by Bosch Rexroth Indramat. It is specifically designed to meet the power demands of the manufacturer's AC servo drives, maintaining an operational balance and efficiency of these drives. The unit employs a dynamic braking action to halt the drives if a fault is detected. Further, an auxiliary capacitance module can be added; this feature helps refrain the bleeder resistor activation during a braking action. It's crucial, however, to ensure this module can accommodate the energy storage demands of the rotational drive.
Key specifications of this power supply include a nominal DC bus voltage of 300VDC, and a three-phase input voltage with a rating of 220VAC. It is equipped with a built-in cooling system to prevent overheating during use. The unit offers two terminals, L+ and L-, for DC bus connection. Security measures include two line input fuses with a 6.3A current rating. The total mechanical output of the related servo drives must not exceed 4.1kW. Two LED displays, H3 and H4, facilitate quick troubleshooting. The model requires no semiconductor integration and features a 50A current rating. Connectivity is simplified with a wire ribbon cable connected through the product's X1 connector. Overall, the module proves effective in implementing a modular design AC drive system, particularly when used with an AC servomotor and AC servo drive from the same manufacturer.
