CHAPTER 2 - SYSTEM DESCRIPTION
8. 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tted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.
