POWER SUPPLY LCA30S-15 HL1055-1 Toyota JAT-710 Air Jet Loom Control Cabinet Part

Product Overview

Switching power supply LCA30S-15 for the Toyota JAT-710 air jet loom. Item code HL1055-1.

This is the 15 V DC unit used in the control cabinet. Its output feeds circuits that behave differently from the 5 V rail, so the failure reads differently too: solenoids or relays that pull in weakly or buzz instead of clicking, functions that work when the loom is cold and fade as the cabinet warms, or an intermittent stop that no error code explains. A supply that sags under load causes all three, and a meter across the output terminals under working load confirms it in a minute.

Applications & Compatibility

Supplied to weaving mills and loom electrical teams servicing JAT-710 control cabinets.

• Compatible with: Toyota JAT-710 air jet loom
• Model marking: LCA30S-15 (15 V DC)
• Our item code: HL1055-1
• Different rail, different item: HL1055 (LCA30S-5, 5 V DC, 64120-03006-00)
• Related control parts: HL1051 / HL1053 function panel boards, HL1052 memory card

No OEM number is marked on this unit beyond the model marking. Confirm that the label on the old supply reads LCA30S-15 and note the output voltage printed beside it. The 5 V and 15 V versions share a housing family but are not interchangeable — fitting the wrong rail can damage the circuits being supplied.

Quality Standard

• Terminal layout and mounting matched to the original bracket, so the unit fits without drilling or adapter plates.
• Output voltage checked under load before packing, not only at no-load.
• Over-current and short-circuit protection verified on each unit.
• Rated for the warm, lint-laden air of a weaving shed rather than an air-conditioned panel room.
• Anti-static bag and shock foam for international freight.
• Video outgoing inspection, including a loaded output test, can be provided on request.
• Warranty covers manufacturing defects (case-by-case evaluation). Damage from incorrect input wiring, over-voltage or a downstream short circuit is excluded.

Frequently Asked Questions

Q1: How do I tell the 15 V unit from the 5 V unit?
Read the model marking on the label: LCA30S-15 is 15 V and LCA30S-5 is 5 V. Both fit similar brackets, so the marking is the deciding detail.

Q2: Solenoids buzz instead of clicking — is the supply the cause?
It can be. Measure the output under load while the loom is running. If the rail drops as the load increases, replace the supply before chasing the solenoids.

Q3: Can I fit the 5 V supply as a temporary substitute?
No. A wrong output rail can leave circuits under-powered or damage them. Use the correct voltage, even if it means waiting a few days for stock.

Q4: Do you support neutral or private-label packing?
Neutral packaging is standard. Custom private-label packaging is available on request.

Q5: What about the warranty?
Warranty is offered against manufacturing defects, evaluated case by case. Damage from incorrect input wiring, over-voltage or a downstream short circuit is not covered.
