IR-TEC PPU-300 is a full featured power pack and controller for low voltage lighting control systems. The PPU-300 not only supplies 24VDC power for the operation of multiple low voltage occupancy sensors, but also provides line voltage load switching in response to signals from connected sensors or control devices. The unit can be attached to a junction box through a ½ inch knockout with the designed threaded nipple and locknut. It may also be mounted into fixture cable trays or located inside an adjacent junction box for specific local code requirements.
The PPU-300 is an isolated class 2 switching mode power supply device for parallel sensor connection up to maximum 150mA capacity. With proper control circuitry, the load can be turned ON and OFF automatically based on inputs from connected occupancy sensor, control device or manual control button. Additional inputs allow connection with control from timer, BAS and/or manual switch for broader applications, such as hold ON or hold OFF control.
It can meet both automatic OFF and bi-level switching with manual ON control required by specific energy codes. Various control modes can be achieved with different wiring connections. Only basic wiring diagrams are illustrated. Contact LeanLight to schedule an IR-Tec team member to help when a more complex wiring diagram is required.
