Description

The Stromwandler SWP P9.55-2 Current Transformer is a high-precision device designed for industrial applications, providing reliable current measurement and protection in demanding environments. Operating at a frequency of 50/60 Hz, it typically supports up to 80 V output with a continuous current of 4 A. Built to withstand extreme conditions, it functions reliably across a wide temperature range from -40°C to +85°C and meets IP67 protection standards, ensuring dust and water resistance in harsh industrial settings.

Constructed in a toroidal (through-core) design, the SWP P9.55-2 allows the primary circuit cable to pass through its center, generating a proportional signal through electromagnetic induction. Its compact size makes it ideal for installation in industrial chiller control panels or confined electrical cabinets. The device comes equipped with standard terminal blocks or leads for easy integration with SWP-series digital controllers or PLC analog input modules.

Applications

Industrial Refrigeration and HVAC Plants: This is its core application area. In large industrial chillers, it monitors the pressure and temperature of the cooling cycle, ensuring the refrigeration compressor operates within safe ranges and preventing overpressure damage.

Precision Hydraulics and Pump Stations: Used in hydraulic pump systems. It stabilizes system pressure, improves hydraulic pump efficiency through precise logic control, and provides reliable monitoring data for preventative maintenance.

Medical Device Manufacturing: Due to its high-precision fluid control capabilities, it is often integrated into medical devices or large diagnostic instruments requiring precise liquid/gas management, ensuring the long-term reliability and safety of the equipment.

Smart Factories (IoT Integration): In factories supporting the Industrial Internet of Things (IIoT), this controller acts as a terminal sensing and actuation unit, transmitting pressure and flow data to a monitoring center in real time, supporting data-driven decision-making.

Physical and Installation Characteristics

Structure: Typically uses a toroidal design. Users must pass the main circuit cable through the center hole of the transformer to obtain the signal using the principle of electromagnetic induction.

Dimensions: This model is a compact component, specifically designed for use in industrial chiller control panels or distribution cabinets with limited space.

Interface Connection: Equipped with standard connectors or leads, it can be directly connected to SWP series digital controllers or PLC analog input modules.

Functions

Current Ratio: This transformer converts the large current in the main circuit into a smaller current (e.g., 50/5 or 100/5, nameplate verification required) according to TME's general standards for instrument measurement.

Accuracy Class: As a measuring-grade transformer, its accuracy is typically in the 1.0 or 0.5 class, ensuring accurate and reliable load data acquired by the controller.

System Protection: In industrial chiller systems, it monitors the compressor's operating current in real time. Once an abnormal current is detected (such as stall or overload), the controller will immediately trigger a protection mechanism to prevent the motor from burning out.
