BOSCH REXROTH HCS03.1E-W0150-A-05-NPBV | IndraDrive C Compact Converter

Product Overview

The Bosch Rexroth HCS03.1E-W0150-A-05-NPBV is an IndraDrive C HCS03 compact converter designed for single-axis drive applications. The HCS03 family converts the incoming three-phase supply into a controlled AC output for operating servo motors, with a compact package that includes the required mains connection components.

This model belongs to the HCS03.1E-W0150 class, which has a 150 A device peak current and operates from a 400–500 V supply. The available product records identify R911305061 with the HCS03.1E-W0150 family and list a 42,000 A SCCR for the configuration.

For replacement work, the complete type code should be matched rather than ordering only by the basic HCS03.1E-W0150 designation. The suffix -A-05-NPBV identifies the specific configuration.

The published HCS03.1E-W0150 family data gives a 150 A device peak current and 400–500 V connection voltage. A corresponding HCS03.1E-W0150 product record lists 225 × 315 × 440 mm and approximately 19.14 kg.

Important Specification Note

⚠️ 42000 A does not mean the converter outputs 42,000 A.

The 42,000 A figure refers to the SCCR — Short-Circuit Current Rating. The electrical operating values are substantially different:

Input: 3 × AC 400–500 V, 106 A
Output: 3 × AC 0–480 V, 95 A
Device peak current: 150 A
SCCR: 42,000 A

This distinction is important when preparing an eBay title or technical datasheet because using “42000A Converter” without explaining SCCR can be misleading.

Typical Applications

⚙️ Servo Motor Control

The HCS03 converter is designed to provide controlled AC power for servo motor applications within the IndraDrive architecture.

🏭 Machine Automation

Typical applications include automated production equipment, machine tools, handling systems, packaging equipment, and other motion-control machinery.

🔧 Replacement & Maintenance

The unit can serve as a replacement converter for existing Rexroth IndraDrive systems where the original HCS03 hardware requires replacement.

📦 Industrial Spare Parts

The compact converter format makes it suitable for maintenance inventories supporting older or continuously operating Rexroth motion-control systems.

Installation & Configuration Notes

Before replacing an existing converter, check the complete type code:

HCS03.1E-W0150
A-05-NPBV suffix
R911305061 material number
Input voltage
Motor/load current requirements
Control unit compatibility
Firmware/software configuration
Motor and encoder feedback configuration
DC-bus and mains wiring
Cooling and cabinet ventilation

The HCS03 converter is part of a larger IndraDrive system, so replacing the power converter alone does not guarantee compatibility with every control section or motor configuration.

Maintenance Recommendations

🔧 Keep the cooling-air path free of dust and debris.

🔧 Inspect the integrated blower and ventilation openings during preventive maintenance.

🔧 Check DC-bus and power terminals for signs of overheating.

🔧 Verify the converter type code before replacing the unit.

🔧 Record motor, feedback, and control-unit settings before removing the existing drive.

🔧 After replacement, perform a controlled commissioning procedure before returning the machine to production.

FAQ

Q1: What is HCS03.1E-W0150-A-05-NPBV?
It is a Bosch Rexroth IndraDrive C HCS03 compact converter for servo and motion-control applications.

Q2: What is the input voltage?
