Single-Phase Slave (PSU-20)
A cost-effective way to expand the capacity of your control system
The Single-Phase Slave (model PSU-20) is an affordable way to increase the capacity of your Phason “slave-capable” control system.
The following Phason controls are slave-capable:
The PSU-20 has one 20 ampere variable AC stage for controlling loads such as variable-speed fans, heat lamps, or incandescent lights. Installation is simple and there is no additional configuration required; all slave units follow the programs and settings of the master control.
Features
- One variable AC output
- Expandable capacity using additional slaves
- Rugged enclosure (corrosion resistant, water resistant, and fire retardant)
- CSA approval
- Two-year limited warranty

The Single-Phase Slave must be on the same phase as the master control. If you are using a Programmable Lighting Control, the more advanced Three-Phase Slave (PLC-2SDC) does not require all units to be on the same phase, allowing you to distribute the load across all three phases.
