The PS 250 power supply contributes power to nLight devices such as thenGWY2 KIT nGWY2 GFX and nGWY2 CTRL and the nGWY2 L400 KIT nGWY2 GFX and nGWY2 CTRL L400 . Wiring to terminal connections on those devices, the PS 250 outputs 4W of low voltage power. For simplifying installation, the PS 250 has an elongated chase nipple. This featureallows it to be attached either directly through a 1/2 in. knockout into a junction box, or inside an adjacent box for meeting specific local code requirements in ceiling plenums.
