Condenser fan speed controller Johnson Controls P315PR-9200C (8-25bar)

P315PR Johnson Controls Direct-mount condenser fan speed controllers for electronically commutated (EC) single-phase motors

The P315PR pressure-input direct-mount condenser fan speed controllers are designed to control the operation of electronically commutated (EC) single-phase motors. Controlling the main pressure in the refrigeration system by changing the speed of the air-cooled condenser fan provides optimal regulation results throughout the system's annual operation.

The P315PR controllers can be used in refrigeration systems that operate with refrigerants that do not cause corrosion.

The pressure transducer at the controller input is the best solution for responding to pressure changes in the refrigeration system. These controllers change the supply voltage to the fan motors in the range from 5% to 95% of the proportional range.

Features and benefits:

• Direct condenser pressure control: By directly controlling fan speed based on condenser pressure, the P315PR controller optimizes refrigeration system operation, resulting in lower energy consumption and better efficiency.
• Easy installation: Direct mounting on condenser pressure fittings enables quick and simple installation, and provides a fast response to condenser pressure changes.
• Setpoint adjustment: The screw adjustment mechanism located on the top of the controller allows easy and precise tuning of the setpoint to meet the application's specific needs.
• Durable enclosure: The IP65-rated enclosure allows outdoor installation, providing resistance to weather conditions.
• Compact design: The small size of the controller enables installation in tight spaces and facilitates mounting on the condenser connection due to its small rotation radius.
• Quick electrical connection: The built-in quick-connect electrical plug enables fast and simple wiring and installation.
• Compatibility with EC motors: The controller is compatible with single- and three-phase EC motors, providing a cost-effective and efficient fan speed control solution for motors of various power ratings.

Notes: The P315PR controller should be used only as a control element within a system. If a failure or malfunction of the P315PR controller could lead to equipment damage or other losses, additional protective measures should be designed into the control system. Other devices such as monitoring systems, alarms or safety controllers should be considered and maintained to warn of failures or protect against their consequences.
