TVM 1.2-050-220/300-W1

Product Description

The TVM 1.2-050-220/300-W1 power supply module made by Bosch Rexroth comes with multiple monitoring capabilities. The X9 connector of this supply module can be used to connect the DC bus voltage and the AC power input through various terminals. The device is compatible with AC servo drives of modular type from the manufacturer. The unit can be fitted with an auxiliary bleeder module or one or more auxiliary capacitance modules. Its dynamic braking feature terminates the power connection to the connected drives when required. The servo drives used with the product can be deployed in machine tools.

The bleeder resistor combined with the product absorbs the regenerated energy when its associated servo drives function as generators. One device can be used with a maximum of six servo drives. It has a line voltage of 3 x 220VAC +/-15% or 3 x 230VAC +10% / -15%. The RESET button of the supply unit is positioned directly above the diagnostics display. The servo drives connected to the unit have a cumulative maximum mechanical continuous output of 4.1kW. If the power supply is fitted with more than one auxiliary capacitance module, each module can store up to approximately 30W.

The drive energy stored in the DC bus circuit of this device is reusable for acceleration. The regenerated power from the connected modular drives is absorbed through a bleeder resistor incorporated in the product. This device is also capable of monitoring the bleeder resistor load. It uses a wire-ribbon cable to supply the signal voltage to the drive. Its Bb contact remains open if the drive or signal voltage bus connection is faulty. The protective earth rail on top of the front panel offers central grounding for each connected drive.
