Round Flat Indicator Light AC 380V

ACXION Round Flat Indicator Light AC 380V is a long-type Φ22 LED indicator built for industrial control panels, distribution cabinets, and switchgear where the control circuit runs at 380V AC. The AC/DC universal wiring scheme means there is no distinction between positive and negative terminals — a practical advantage in high-volume panel assembly where wiring errors on indicator circuits waste time during commissioning. The rear cover color matches the lens and LED color, so assemblers can confirm the correct indicator color from the back of the panel without checking the front.

At ACXION, we pay close attention to LED binning consistency on this model — panels with rows of indicator lights look unprofessional when brightness varies between units, and OEM/ODM buyers assembling large distribution boards have flagged this as a quality issue with other suppliers. We select LEDs from consistent batches to avoid visible brightness variation across the same panel.

Features

Direct 380V AC connection: No step-down transformer required — connects directly to 380V AC control circuits, simplifying panel wiring and reducing component count
AC/DC universal wiring: No positive/negative distinction at the terminals — reduces wiring errors during high-volume panel assembly
Color-coded rear cover: Rear cover color matches lens color, allowing assemblers to verify indicator color from behind the panel without checking the front
Side illumination: Light disperses to the side as well as forward, improving visibility from angles in crowded panel environments
High IP rating option: Front panel protection up to IP66 available — suitable for washdown environments, outdoor enclosures, and dusty industrial locations
Wide operating range: -40°C to +85°C operating temperature; altitude up to 5000m; salt spray resistance up to 500 hours; UV resistance up to 500 hours
Multiple standard colors: Red, green, yellow, blue, white as standard; orange and amber available on request

Frequently Asked Questions

Q1: Why choose a 380V indicator light instead of a 24V version with a transformer?

A 380V indicator connects directly to the 380V AC control circuit without any additional components. The alternative — using a 24V indicator with a step-down transformer — adds cost, takes up panel space, and introduces an additional component that can fail. For panels where the control circuit already runs at 380V, the direct-connection approach is simpler and more reliable. The 380V version is standard in Chinese industrial panels and widely used in export panels built to IEC standards.

Q2: What does “AC/DC universal wiring” mean in practice?

It means the indicator has no designated positive or negative terminal — either terminal can be connected to either wire of the AC circuit. In DC applications, polarity does not matter either. This eliminates a common wiring error in panel assembly where an indicator is wired with reversed polarity and fails to light up, requiring the assembler to go back and swap the wires. For OEM panel builders assembling large quantities, this saves meaningful time during production.

Q3: What is the difference between this long-type and the short-type indicator light?

The long type has a longer body that extends further behind the panel, which affects how it fits in panels with limited front-to-back depth. The short type is more compact and suited to shallow enclosures. Electrically and functionally they perform the same — the choice depends on your panel depth and mounting constraints. Check the product dimensions against your panel cutout depth before ordering.

Q4: Can the lens be engraved with symbols or text?

Yes. The mask surface can be laser engraved with characters, symbols, or abbreviations — useful for panels where the indicator function needs to be marked directly on the lens rather than on a separate nameplate. Common requests include power symbols, phase labels, or status text. Specify your engraving requirement when ordering.

Q5: What colors are available and can we order mixed colors in one batch?

Standard colors are red, green, yellow, blue, and white. Orange and amber are available on request. Mixed-color orders within a single batch are accepted — specify the quantity breakdown per color when placing your order and we will confirm availability.
