BOC EDWARDS EXC-300-M controller

category : pre-owned
status : available
price : EUR 975.-- per piece (EXWORKS, excl. VAT)

This controller has been used for short period on a demo vacuum system and is in new condition. Available from stock with warranty.

Product description
The EXC Controller generates the electrical supply and the control signals necessary to operate an EXT pump and its accessories. This EXC300M is strictly suitedy for the BOC magnetic turbo pumps.

The Controller has a high-efficiency, auto-ranging power supply which adjusts itself to any external electrical supply in the specified voltage. The power supply converts the single-phase electrical supply into a regulated d.c. electrical supply to control the operation of the EXT pump.

The pump has three Hall effect devices which operate as rotor position sensors. These sensors ensure that the drive current is correctly switched to the phase-windings of the pump-motor. The Hall effect devices also generate a speed signal which the Controller uses to regulate the rotational speed of the pump.

The Controller has a secondary regenerative supply which uses the d.c. motor of the EXT pump as a generator. If the electrical supply fails, the regenerative supply provides the Controller with a back-up source of power without the need for batteries. The Controller uses the regenerative supply to maintain the electrical supplies to the vent-valve, air-cooler and AIM gauge (if connected) until the pump speed falls to below 50% of full rotational speed.
