Rexroth R911268888 – TVD 1.3-15-03 Servo Power Supply
Product Overview
The R911268888 is the Bosch Rexroth Indramat reference for the TVD 1.3-15-03 servo power supply used in ANAX and DIAX01–03 drive systems. It converts three-phase AC mains power into the DC bus supply required by compatible Indramat drive controllers and servo amplifiers. Available technical references identify a 380–480 VAC three-phase input, a 320 VDC DC-bus output, and a 15 kW continuous DC-bus power rating. The unit belongs to the TVD supply-unit family and includes monitoring functions intended for industrial electric-drive applications. It is particularly relevant when maintaining legacy Indramat motion-control systems in machine tools, production machinery, and automated manufacturing equipment. Since the product is discontinued, exact type-code matching is important when sourcing a replacement or refurbishment unit.

Key Features and Benefits — R911268888
- Three-phase AC input for industrial drive systems.
- 320 VDC nominal DC-bus supply.
- 15 kW continuous DC-bus power capability.
- Designed for compatible Indramat servo-drive architectures.
- Integrated monitoring functions for supply operation.
- Suitable for multi-axis machine-control applications.
- Useful as a maintenance spare for legacy Rexroth motion systems.
The power supply is a system-level component, not an individual servo amplifier. Personally, I would verify the connected drive modules and DC-bus requirements before approving a replacement.

Installation and Maintenance — R911268888
Before installation, verify the three-phase input voltage, DC-bus requirements, connected drive modules, cabinet ventilation, grounding, and precharge arrangements. Because the DC bus can retain hazardous voltage after power removal, follow the applicable lockout and discharge procedure.
During maintenance, inspect power terminals, DC-bus connections, cooling paths, connectors, and visible signs of overheating. Check the supply’s diagnostic indications before replacing it. After installation, verify the DC-bus voltage and drive-system status under the approved commissioning procedure.
Product Warranty — R911268888
Warranty coverage should be confirmed according to the supplied condition, such as new surplus, refurbished, repaired, or tested-used. For critical motion-control spares, procurement records should include the complete type code, serial information, inspection status, and applicable warranty period.
When sourcing the Rexroth R911268888, verify the TVD 1.3-15-03 type code, 380–480 VAC input requirement, 320 VDC bus, and 15 kW rating before purchase.
