Development
We collaborate with companies which require relatively small quantities of a specific unit which would carry out control tasks. Usually, these are electronic or electric/electronic devices which can be produced using a printed circuit board as a base. Companies which work in the pumping or packaging industries are prime examples of those needing custom-built control equipment.
Two examples of such units are firstly, one which accepts an input from a float or pressure switch and which drives a single phase, 1.5kw pump motor. It is microprocessor-controlled and allows a pump to run for a maximum period of time before switching it off, waiting, then running again. It also then allows the pump to run on following the emptying of its tank.
The second unit, also for pump control, accepts an analogue level input from a pressure tube and switches a pump motor on and off. It also delivers a volt-free alarm output which can be used to power a remote device to signal an abnormally high or low level. Being microprocessor based, we are able to program preset levels into it to suit different customer requirements or we are able to incorporate an adjustable preset control.
Repairs
We repair industrial electronic equipment, particularly variable speed drives and soft starters. To this end, we maintain small stocks of IGBT output modules, half-controlled rectifier stacks and power capacitors.
We are able to modify or repair electronic control equipment on site if required.
We supply ARROW automatic voltage regulators for generators.
