A 2.10 Switched power pack
Supply of the ekrPro Com
60
including the BST components takes
place over the switched power pack.
There are two supply possibilities:
1. over a central power pack in the machine
2. over a power pack allocated to the BST part
The following details are based on a control system comprising a
control unit ekrPro Com
60
, analogue sensors, sensor adjustment
unit and actuator (EMS1, EMS5, EMS10, EMS16, EMS17 or
EMS20)
1. Central supply
If supply takes place centrally from the machine the following
parameters are to be fulfilled:
• Output voltage: 24 V DC ± 5%
• Output current: 4.2 A DC
• Output power: 100 W
The power pack must be able to quickly charge (~ 5 sec) the input
capacitance (approx. 950µF) of the control amplifier after switching
on without recognizing this as a short circuit and so switching off
again.
The output should be permanently resistant to short-circuiting,
overloading and idle running.
2. Separate power pack
If a separate power pack is used for the BST components, we
recommend the use of units manufactured by PULS GmbH:
Input voltage: 85 - 264 V AC or 220 – 375 V DC
Output voltage: 24 V DC ± 5%
Output current: 4.2 A DC
Output power: 100 W
BST order number: 103 837
If a number of control systems are to be supplied from a single
switched power pack, then, dependent on the total required power,
the following power packs are also available:
