Acro NEMA Part Night

WESTIRE ACRO SERIES

Engineered for energy saving applications

Accuracy

The AcRo NEMA Part Night photocell utilises a filtered silicon based ambient light sensor and microprocessor control. This accurate combination provides the best energy savings and reliable operation.

Longevity

Engineered in the EU, with a 15 year design life and manufactured in-house using only high quality name brand components, the AcRo series photocells are renowned in the industry for their unparalleled quality and reliability.

Early failures are eliminated by an intensive 48 hour burn-in of each photocell. This eliminates infant photocell mortality before our products are shipped.

Features & Benefits

  • Switches the light off at a predetermined time for a number of hours each night.
  • Designed to meet the needs of LED fixtures while still maintaining proven reliability for more traditional technologies.
  • Energy efficient design with an average power consumption <0.25 watts.
  • Low Profile enclosure.
  • A 48 hour operational burn-in test is performed on every unit before leaving the factory.
  • ROHS compliant.
  • UV stabilised polycarbonate housing is rated and tested to IP 65.
  • Electronic design outperforms thermal controls.
  • Colour option available: blue, green, black, red and clear.

Applications

Various applications, the Acro Part Night switches the light off at a predetermined time for a number of hours each night,  for example, on from dusk until midnight, off for five hours, on again until dawn.
