HE1HWPR/05 Application Field and Working Principle

The HE1HWPR/05 is a versatile, easy-to-use power module designed and manufactured by EquipSystems. It is a modern based power product, delivering precise power control, providing optimal performance for both startup and regulation. This product series provides a wide range of control features, including speed control, power adjustment, overload protection, temperature monitoring and remote monitoring functions. The HE1HWPR/05 series is suitable for most industrial power applications including motor control, machinery, automation, and instrumentation.

Description of Product

The HE1HWPR/05 is a fully integrated, single-box and field-oriented Adaptive V/Hz (AV/Fz) power module that features an embedded, high-resolution 24-bit D/A converter. This device is capable of controlling three-phase induction, synchronous and universal motors across a wide voltage range (up to 480Vac) and full rated current (up to 9.7 A). It offers an ultra-low voltage drop across the converter and extremely low power loss thanks to its power transformer, allowing for lowered system cost. In addition, this power module incorporates numerous advanced safety features, including overcurrent, overvoltage, and overtemperature protection, as well as system level isolation (including galvanic separation) for maximum noise immunity and electromagnetic compatibility. Its integrated NTC temperature sensor and ambient temperature sensor make it an ideal choice for diagnostics and protection of motor-related components.

Application Field

The HE1HWPR/05 power module offers unsurpassed power efficiency and simplicity of operation across a wide range of industrial applications. Thanks to its high-resolution 24-bit D/A converter, the HE1HWPR/05 is ideal for high-speed, precise control of machinery, automation systems, instrumentation, and other motor-driven equipment found in factories, industrial plants, and laboratories. It can be used in applications that require varying speeds, regulating power, overload protection, and temperature monitoring. The overall performance and reliability offered by the HE1HWPR/05 make it an excellent choice for applications in industries such as automotive and aerospace, power generation and transmission, and consumer electronics. It is also well suited for water/wastewater treatment, unconventional oil & gas production, chemistry & refining, agricultural and construction machinery, and food processing.

Working Principle

The HE1HWPR/05 power module works on the basis of an Adaptive V/Hz (AV/Fz) control philosophy. This is a closed-loop, field-oriented control strategy that allows for precise adjustment of the voltage and frequency of the motor, resulting in optimal performance at a range of operating conditions. In operation, the voltage and frequency are periodically adjusted to ensure constant torque delivery as the motor output speed changes. This is achieved by calculating the set-point voltage and frequency values, based on the motor speed and load. The Integral Proportional (IP) proportional-integral controller continuously adjusts the output voltage and frequency in line with the measured values, ensuring the motor runs at its optimum efficiency as conditions vary.This power module also incorporates a host of safety features such as auto-reset power supply module, overcurrent, overvoltage, and overtemperature protection to keep your motor safe from damage even in challenging environments. Furthermore, its automatic voltage regulation (AVR) ensures that a correct output voltage is maintained regardless of input voltage fluctuations. The HE1HWPR/05 power module provides an economical and efficient solution for a range of industrial motor control applications. As a result of its comprehensive suite of features and control strategies, this product delivers outstanding levels of reliability and performance. By choosing this product, installers and end-users can enjoy significant energy savings and process control accuracy.
