ELAU PS-4/10/16/230/00 PacDrive SCL Power Supply

The ELAU PS-4/10/16/230/00 is the central power supply for a legacy PacDrive SCL servo system. It converts a 220 to 240 V single-phase or three-phase mains input into the DC bus and regulated 24 V control supply used by the SCL system through the PD-8 distribution module. Integrated braking, diagnostics, and SERCOS connectivity support coordinated machine operation.

The unit is designed specifically for the 230 V SCL architecture and is not a general-purpose 24 VDC power supply. It must not be coupled to a 400 V MC-4 DC bus. Correct replacement requires the complete model code, order number, mains configuration, total SCL load, PD-8 wiring, SERCOS topology, and cabinet cooling to be checked.

Key Features

• Central DC bus and 24 V control supply for PacDrive SCL systems
• Supports 220 to 240 V single-phase or three-phase mains input
• 16 A continuous DC output with three-phase supply and 10 A with single-phase supply
• Integrated braking resistor for regenerative energy management
• SERCOS fiber-optic communication and ready-status signaling
• Designed to distribute power to SCL axes through the PD-8 module

Typical Applications

• Legacy PacDrive SCL packaging machines
• Distributed servo systems using a PD-8 power distribution module
• Cartoning, filling, labeling, and handling equipment
• Retrofit or replacement of the original SCL central power supply
• Machines with a 230 V SCL power architecture

Compatibility and Selection Note

Use PS-4/10/16/230/00 and order number 13130258 as the primary identifiers. Confirm whether the machine uses single-phase or three-phase 220 to 240 V input, calculate the connected SCL load, and verify PD-8, SERCOS, ready-contact, braking, and cabinet connections before commissioning.

FAQ

What does the PS-4 power in a PacDrive system?

It supplies the DC bus and regulated 24 V control power for PacDrive SCL servo modules connected through the PD-8 distribution module.

Can the PS-4 use single-phase mains power?

Yes. It accepts 220 to 240 V single-phase or three-phase input. Continuous DC output is 10 A on single-phase and 16 A on three-phase.

Is this a general-purpose 24 VDC power supply?

No. It is a dedicated SCL system power supply with DC bus, braking, control power, diagnostics, and PacDrive interfaces.

Can it be connected to the DC bus of a 400 V MC-4 servo drive?

No. The PS-4 is designed for a 230 V SCL architecture and must not be coupled to the 400 V MC-4 DC bus.

Does the unit include braking hardware?

Yes. It includes a 21.5 ohm braking resistor rated at 100 W continuous and 7 kW peak.

What should be checked when replacing a PS-4?

Verify the complete model and order number, mains phase arrangement, connected SCL current, PD-8 wiring, 24 V load, SERCOS connections, ready contact, cooling, and safety isolation.
