AC TO DC POWER SUPPLY UNITS

8.1

Types of Power Supply Unit

There are two types of AC to DC power supply units:
a.
8-Way AC to DC Power Supply Unit (Part Number 05701-A-0406)
A 1U high half width 19 inch rack mounted unit that contains a
single 50W Switched Mode AC to DC Power Supply Module.
b.
16-Way AC to DC Power Supply Unit (Part Number 05701-A-0405)
A 1U high 19 inch rack mounted unit that contains a single 50W
Switched Mode AC to DC Power Supply Module.
Both power supply units will operate from an 85V to 264V, 47Hz to
440Hz ac supply, or a 110V to 340V dc supply (Refer to Zellweger
Analytics for information on dc supplies).
8.2

Power Supply Unit Upgrades

Both power supply units are provided with internal connections to
enable a power upgrade to 100W by the addition of a second 50W
Switched Mode AC to DC Power Supply Module (Part Number 05701-
A-0440).
A second sub-unit (Part Number 05701-A-0441) can be fitted to the
basic 16-way power supply unit if more than 100W is required to
operate the system. The additional sub-unit will contain a 50W Switched
Mode AC to DC Power Supply Module as standard and will therefore
give an additional 50W of available power. If required a further 50W
Switched Mode AC to DC Power Supply Module (Part Number 05701-
A-0440) can be added to this second sub-unit to bring the power
availability up to 200W.
The switched mode power supply modules used are fully overload
protected and are designed to be connected together.
8.3

Power Supply Connections

The input ac power supply is connected via a three core cable at the
rear of each unit.
The nominal 24V dc output supply is connected via a twin core cable
at the rear of each unit.
