Description
The PS300 is intended for use in commercial environments. It is designed with field selectable set points from as low as 30 Pa to as high as 300 Pa. The NO/NC switch has a 3A Resistive Load limit, which can be used for space heaters or lighting control. The lower 2A Inductive Load limit is more suited for use with coils, pumps, fans or solenoids. Alternatively, you can always connect through an external relay with a higher rating.
Applications
- Standard Pre-Filter Monitoring: Pleated panel pre-filters (M5 or M6) that start with an initial pressure drop of 50 Pa and are scheduled for replacement once they reach 150–250 Pa.
- Basic Duct Static Pressure Control: Verifying adequate negative or positive pressure in simple exhaust systems.
