Alternating boxes

The Alternating Control Boxes of micro controle are designed to control and protect two submersible pumps.

The versions include the ALS 200 model for pumping systems for sanitation and the ALH 200 for pumping systems for hydropressors.

They act against the lack of water, the excessive consumption of the motor (thermal trigger) and hold the control circuit through a circuit breaker.

The range is available in single-phase and three-phase versions, with different thermal settings between 1.6 and 14.0 Amp.

Contingency Plan Communication micro controle

Dear Customers and Partners,

We followed the development of the situation caused by COVID-19 with attention, and we support the measures and guidelines of WHO, DGS and the Government of Portugal.

Micro controle continues to develop its activity, having taken additional protective measures through the proper disinfection of our facilities and equipment, the provision of alcohol-based solutions for disinfecting hands, and alerting to the practice of frequent washing of hands with our Employees.

We reorganized our production unit, so that each Employee works with the recommended safety distances.

Order deliveries are maintained using our logistics partners. We are available for contact through the usual means.

For the convenience of our customers, you can place your orders through our online store.

We assume a responsible attitude and we are permanently attentive to the WHO guidelines, which we share here: https://www.who.int/news-room/q-a-detail/q-a-coronaviruses


Dual Alternating Modular Relays

The dual alternating modular relays are important allies of submersible electric pumps installed in sanitation or hydropressing plants.

As they are modular, their installation is simple and can be used in standard electrical box boxes or modular boxes on the DIN rail.

The model used for installation in a sanitation plant (RAL 202 SAM) is different from that for a hydropower plant (RAL 202 HIM). Also for each of these two models there is the variation for single-phase voltage and for three-phase voltage.

These devices also include the box of 2 modules and the fact that the various timings can be adjusted by Micro Switch, which gives high flexibility and resource saving.

The dual alternating modular relays control and protect the electric pumps (two) allowing alternating operation, acting in situations of minimum level, maximum level, backup pump input reinforcement and depending on model, maximum alarm (RAL 202 HIM) or minimum alarm. (RAL 202 HIM).

In the video below, it is possible to observe the operation of the RAL 202 SAM (Switching Relay for Sanitation Plants) in the various predicted situations.

All applications, detailed operation and data sheet, are presented here. Both are available for sale in the online store, starting at € 46.40.

Discontacting boards

Micro controle extends its offer in Control Boards, launching the new segment of Discontactors.

This is a board that ensures the control and protection of electro-pumps, used in the supply of water under pressure and in irrigation systems, in situations where it is not necessary to use the Level Relay.

In some scenarios, the defenses against the lack of water may simply not be necessary, and it may also be the case that this is already assured by a float or pressure switch.

With a Thermal Regulation from 2.5 to 13 A (see selection ranges) and with option of Voltage between 230V and 400V, the Discontactors of the micro controle also offer a model with Contactor and Thermal Relay Schneider. The base version is equipped with Maxge, in these components.
