Load Controls INC PH-3A-HG Filter Module

Load Controls INC PH-3A-HG Filter Module   

Product Details Introduction

Load Controls INC PH-3A-HG is a PH-3 series integrated power sensing module (Power Cell) produced by Load Controls in the United States. Its core is used for three-phase motor load monitoring, power conversion, and signal filtering output. It is widely used for load monitoring, overload protection, and energy consumption analysis of equipment such as machine tools, pumps, fans, and compressors.

Core parameters and characteristics of the product

Model positioning: PH-3A series HG specification, integrated power sensing/signal conversion module, built-in current/voltage sampling, filtering and transmission circuit.

Electrical specifications: Suitable for 208-460V three-phase motors, rated current 4.2A, supporting wide voltage industrial power grids.

Measurement principle: No external CT/PT, direct clamp sampling, real-time monitoring of motor active power and load percentage.

Signal output: Standard 4-20mA analog quantity (load/power proportional), compatible with PLC, DCS, recorder and upper computer.

Filtering characteristics: HG represents High Grade filtering, which suppresses motor harmonics and electromagnetic interference, and provides stable and smooth output.

Response speed: The response time is about 15ms, quickly capturing load fluctuations and suitable for dynamic condition monitoring.

Accuracy index: Measurement accuracy of ± 0.5%, excellent repeatability, meeting the requirements of industrial precision load control.

Installation method: Compact module, rail/panel installation, size approximately 23 × 11 × 3cm, weight approximately 0.6kg.

Output impedance: 500 Ω in 4-20mA mode, 2k Ω in 0-10V mode, suitable for mainstream control systems.

Working environment: temperature -20 ° C~+55 ° C, humidity 0-95% (no condensation), industrial grade stable and reliable.

Protection level: Enclosed metal shell, resistant to dust and electromagnetic interference, suitable for harsh workshop environments.

Application scenarios: Machine tool spindle load, pump/fan energy consumption monitoring, motor overload protection, crushing/conveying equipment blockage detection.

Convenient wiring: The terminals are directly connected to the three-phase power supply and output, without the need for additional sensors, making on-site debugging simple.

Function extension: Supports load upper and lower limit alarm, power accumulation, trend recording, and cooperates with the upper computer to achieve energy consumption management.

Durability: No moving parts, maintenance free, long average time between failures, suitable for 24-hour continuous operation.

ending

PH-3A-HG, with its core advantages of high filtering, high precision, integrated design, and maintenance free, is a mature solution for industrial motor load monitoring and power signal transmission, especially suitable for working conditions with strong harmonic interference and stable output requirements.
