Mains power supplies for the ZoneMaster II and ProcessMaster

We can supply suitable ”battery eliminators” for these products as shown above. Suitable units are also usually available from electrical shops, or you may have a suitable unit to hand. However it is important that the power supply does not produce an excessive voltage as this can damage the ZoneMaster and ProcessMaster, and such damage will not be covered by the guarantee. Before connecting your power supply read the specification below and contact us if you are in any doubt.

Required Specification for a mains power unit:
Output voltage 7.5v regulated, 9v regulated, or 6v unregulated. Do not connect an unregulated supply of more than 6v as these units often output voltages of up to 50% more than the rated output. Voltages of 10v or more will damage the ZoneMaster and ProcessMaster.
Maximum current consumption is less than 100mA, so any unit capable of providing 100mA or more is suitable.
Output connector: 2.1mm centre pole positive.

Battery life for the ZoneMaster II is likely to be long enough to obviate the need for a power supply, especially if an Alkaline type is used.
