Siemens 3rx9501-0ba00 As-i Power Supply 3A 30V Dc IP20

Product Description

The SIEMENS 3rx9501-0ba00 is an AS-Interface power supply unit designed to power AS-i network segments in industrial control and automation installations. It accepts an input of 120 volts or 230 volts AC and delivers a regulated output of 30 volts DC at 3 amps to the AS-i bus. The unit carries an IP20 enclosure rating, making it suitable for cabinet-mounted deployments. Integrated ground fault detection and integrated overload detection are built in, reducing the need for external protective devices. AS-i data decoupling is also incorporated, allowing data signals to coexist on the power bus without interference. Licensed electricians and industrial controls technicians are the primary installers.

This power supply is used in AS-Interface network installations where a dedicated, code-compliant bus power source is required. Typical applications include panel-mounted AS-i segments in manufacturing, process control, and building automation environments. The dual-voltage input range of 120 volts to 230 volts AC allows deployment in both North American and international electrical systems without a separate transformer. Its compact, DIN-rail-compatible form factor suits it for use inside control enclosures alongside PLCs, relays, and other automation components.

Key Features

• Dual input voltage: 120 volts or 230 volts AC for wide deployment flexibility
• Regulated AS-i bus output: 30 volts DC at 3 amps
• Integrated ground fault detection reduces external protective device requirements
• Integrated overload detection for bus and connected device protection
• Built-in AS-i data decoupling allows simultaneous power and data on the AS-i bus
• IP20 enclosure rating suitable for clean, cabinet-mounted environments

Compatibility

Designed as a power supply for AS-Interface bus network segments requiring a 30 volts DC, 3-amp source with integrated data decoupling.

Installation Notes

Installation should be performed by a qualified electrician or licensed industrial controls technician in accordance with applicable NEC requirements and the panel manufacturer guidelines. Disconnect and lock out all incoming AC power before wiring the input terminals. Verify that the supply voltage matches the selected input tap before energizing. Do not exceed the 3-amp continuous output rating of the AS-i bus segment supplied by this unit.
