PUMA - Pump control

PUMA – Pump Control is a universal compact single-pump controller with the possibility of communication

The PUMA - Pump control operates both 1- & 3-phase pumps

This device is a versatile and compact single-pump controller equipped with communication capabilities. It has the ability to operate both 1-phase and 3-phase pumps, handling currents of up to 12A (5.5KW). The pump controller features a robust two-part, impact-resistant IP65 encapsulated housing, which guarantees durability and protection against harsh environments.

Notably, the PUMA cabinet’s compact size, measuring only 23cm in width, allows for easy mounting on walls, street cabinets, and other enclosures. Its user-friendly design facilitates easy connections using bottom-mounted fittings, screw terminals, as well as spring clamps.

Communication with PUMA - Pump control

Experience versatile choices: As standard, PUMA is delivered without a communication interface. However, you have the option to enhance it with optional LTE-m 4G or NB-IoT modems. Notably, the communication module is designed with easy replacement capabilities to support future IoT requirements.

In terms of security, PUMA utilizes the ModBus TCP/IP protocol, which can be encrypted via TLS. This guarantees the highest standards for secure communication. Impressively, all PUMA registers share the same data type, which streamlines data transmission as it only requires one telegram to get updated data.

Choose how you want PUMA to operate. It can function as a stand-alone unit for direct communication, or integrate seamlessly with AcowaDash. which enables a wide range of protocol types such as REST, API etc.

User interface and visualization with PUMA - Pump control

Facilitating seamless daily operation, PUMA is equipped with a 2.4″ OLED display on the front and 4 user-friendly control buttons.

Besides its user-friendly interface, PUMA also offers the advantage of using the free configuration tool, AcowaZoo, for seamless control and visualization. Alternatively, users can opt for AcowaDash, providing even more options for efficient pump control.”

Data Collection with external equipment

The PUMA can basically collect data and log signals of several different types by utilizing external standard 4-20mA / 0-10V DC or standard DI equipment. This feature enhances versatility, making the PUMA an ideal choice for diverse monitoring and logging needs.
