More Information

Overview Manuals Power Design Protection Status and Braking Application
  • BA4 supply unit for the SOCAPEL ST1 digital motion controller system
  • Provides a nominal 310 VDC bus from a nominal three-phase 220 VAC supply
  • Delivers 8 kW continuous output for the connected ST1 drive arrangement

SOCAPEL BA4/30-50-310 supplies the common DC bus used by compatible ST1 drive modules.

The historical manufacturer manual documents the input range, bus voltage, surge-current limit, protection set, and transformer requirements for this exact BA4 catalog number.

System planning must preserve the documented transformer, grounding, inrush-limiting, and dynamic-braking arrangements.

Availability, condition, price, and shipping time for SOCAPEL BA4/30-50-310 are confirmed during quotation.

  • Add external inrush-current limitation when transformer rating exceeds 2 kVA
  • Install the documented IP20 protection set around the power connections
  • Maintain the protective-earth and grounding-strap arrangement shown in the ST1 manual
  • Use the documented EMC filtering and cabinet shielding practices
  • Use the auxiliary-supply, overtemperature, and high-bus indications during diagnostics
  • Retain the documented dynamic-braking resistor selection and wiring
  • Provide cabinet cooling and resistor placement suitable for braking heat dissipation
  • Common DC-bus supply for SOCAPEL ST1 multi-axis drive cabinets
  • Machine-axis systems using ST1 drives with configured dynamic braking
  • Industrial motion systems supplied from an isolated three-phase 220 VAC source
Description
SOCAPEL BA4/30-50-310 is the BA4 supply unit used within the ST1 digital motion controller system.

The unit accepts a nominal three-phase 220 VAC main supply and provides a nominal 310 VDC bus with 8 kW continuous output for connected ST1 drive modules.

Before installation or replacement, confirm the isolation-transformer arrangement, protective-earth connection, IP20 protection set, dynamic-braking circuit and any external inrush-current limiter required by the transformer rating.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Does SOCAPEL BA4/30-50-310 require an isolation transformer?
Yes. The ST1 manual specifies transformer isolation for the BA4 supply arrangement and normally assigns a floating secondary to each BA4 unit.
When does SOCAPEL BA4/30-50-310 need an external inrush-current limiter?
The manual requires external inrush-current limitation when the connected isolation transformer is rated above 2 kVA.
Why is the IP20 protection set important on SOCAPEL BA4/30-50-310?
It provides the documented finger-safe protection around the power connections; removing it can expose the nominal 310 VDC bus.
Can SOCAPEL BA4/30-50-310 be selected only by its 8 kW rating?
No. Confirm the complete catalog number, supply range, cabinet layout, transformer arrangement, braking circuit and connected ST1 drive configuration.
What do the status indicators on SOCAPEL BA4/30-50-310 report?
The manual identifies indications for auxiliary supply availability, excessive temperature and high DC-bus voltage; use them together with measured supply conditions during troubleshooting.
How should dynamic braking be checked when replacing SOCAPEL BA4/30-50-310?
Retain the documented resistor configuration, wiring and enclosure cooling arrangement; the braking resistor must be selected for the installed drive system, not by appearance.
Is SOCAPEL BA4/60-80-310 a direct replacement for SOCAPEL BA4/30-50-310?
No automatic equivalence is documented. The larger BA4 version has different capacity and outline data, so the exact supply-unit code and cabinet design must be verified.
