Rectangular plastic LED driver housing with side terminals

Hubbell Incorporated

Hubbell Incorporated LED50W-040-C1250-D ballast 1250mA 50W

SKU CH-B96W-29JZM

Constant-current LED driver supplies 1250 mA at 20-40 Vdc for up to 50 W from a 100-277 Vac input, with IP66-rated plastic housing for dry and damp locations

  • Constant 1250 mA output drives LEDs evenly
  • 50 W maximum power supports bright installations
  • 100-277 V input works on common mains
  • IP66 rating resists dust and water jets
  • UL listed for dry and damp locations

Constant-current 1250 mA driver

This constant-current LED driver delivers a fixed 1250 mA output across a 20-40 Vdc range for a maximum of 50 W. It accepts a wide 100-277 Vac input, making it suitable for commercial and industrial lighting installations that require precise current regulation.

IP66 housing with thermal-advantage plastic

The UL-rated enclosure is listed for dry and damp locations and carries an IP66 rating, protecting the electronics from dust and powerful water jets. The thermal-advantage plastic housing dissipates heat without a fan, so operation remains silent and power factor stays high under normal load.

Wired into 100-277 Vac mains for 50 W LED loads

The unit connects directly to line voltage, removing the need for a separate low-voltage supply. Its constant-current design frees the installer from matching forward-voltage bins, while the damp-location rating allows placement in canopies, sign boxes or covered outdoor fixtures.

Questions about this item

How is the LED50W-040-C1250-D installed, and which wiring step causes the most errors?

Connect the 100-277 Vac input leads to line voltage and the 20-40 Vdc output leads to the LED load, observing polarity; the most common error is reversing the constant-current output wires, which prevents the 1250 mA regulation from starting.

What maintenance or replacement will this ballast need over time?

The IP66-rated plastic housing is sealed and has no user-serviceable parts; plan to replace the entire driver once the electrolytic capacitors reach end of life, typically after 50 000 hours of operation at rated load.

What is the first limit reached when the driver runs continuously at full load?

The thermal limit of the plastic housing appears first; sustained 50 W output in a poorly ventilated enclosure will trigger the internal overtemperature protection and reduce output current below 1250 mA.
