Specifications

Supply types & Description

Three different types of power supply unit may be used with BB100 consoles.

The type supplied depends on the console size and date it was built.

The PSU 300 and the MPS 20 are switch mode supplies whilst the MPS 5

is a linear supply.

There are no user serviceable parts in the units. In the event of failure for any

reason, the switched mode module should be replaced with a spare and the

faulty module returned to AMEK for repair or replacement subject to current

warranty conditions. All switched mode modules must be fitted by qualified and

approved technicians.

Main Voltage Selection

PSU 300 / MPS 20

The MPS 20 and the PSU 300 are auto-ranging units and do not require any

adjustment for the mains input. The supply ranges for the correct operation are

90v – 254v AC @ 47 – 63 Hz.

MPS 5

Do not change the voltage setting without first turning the unit off and

removing the mains lead.

The MPS 5 mains input has to be selected for the level of local mains voltage

supply. The supply may be preset at the factory for your mains voltage but this

must be verified before switching on or serious damage may result. Amek

cannot accept responsibility for failures caused by wrongly adjusted power

supplies. Voltage selection is achieved by positioning the fuse carrier so that the

required voltage appears next to the arrow which is moulded in the connector.

In this way the unit is set up for operation at one of the following ranges of

mains supply.
