The manual barrier from Alphatronics has a modern design and provides reliable security to control access in applications with low frequency of use. The manual barrier 'ManuBar' is produced in aluminum, resistant to all weather conditions. The manual barrier comes complete, including barrier boom, and gas spring matched to the boom length. The length of the barrier arm is available from 2 to 7 meters. The manual barrier is easy to install and maintenance-free.

This fan speed controller is used to control EC fan speed. The unregulated output can control a water valve or an electric heating element. Via the rotary knob the temperature can be set between 5 - 35°C. Fan speed is regulated manually in 5 steps, there's an Off-position and automatic mode. In automatic mode a temperature sensor PT500 is required. Choice between cooling/heating mode can be done via Modbus communication or a jumper. This controller can be connected to our SenteraWeb or a BMS-system. .

This controller regulates the fan speed of single-phase motors from 1,5 to 10 A via phase angle control a.k.a. Triac technology. The supply voltage of 230 VAC can be turned off via the illuminated ON/OFF switch on the side of the unit. Via de potentiometer located on the front of the controller you can set the desired fan speed. Minimum speed can be adjusted via an internal trimmer and kickstart/softstart by adding/removing a jumper on the PCB of the controller. This controller is typically used to regulate the speed of AC fans or centrifugal pumps in HVAC systems. The regulator is also available with TK monitoring. This function will deactivate the motor in case of overheating. The code for this type of regulator suitable for 1,5 A is ITRS-15-DT.
