1070070783
The 1070070783 (VMA 70CR 001-D) is an industrial power supply module produced by Bosch Rexroth Indramat. Rated at an output of 70A, it can be connected to a supply voltage of 3 x 400 to 460VAC with a frequency range of 48 to 62 Hz. The module can be integrated with a VM/RMC backplane component and requires a 24VDC load power supply module that conforms to EN 61 131 specifications. Features include two multi-digit displays, an X27 slot for a memory card, and two DC link test sockets located on the front panel.
Weighing 14.3kg with a width of 150mm, the power supply module has an operating temperature limit of up to 55°C, although performance may decrease. The module has a line monitor for single-and multiple-phase mains failure and can instantly turn off connected drives in case of overvoltage or overcurrent. Additionally, it can endure short-term failures gracefully. However, caution should be taken during use, as the conductive bars on the backplane can become electrically charged. Therefore, a clearance of at least 1mm is required between the current module and the power supply unit during assembly.
