Introduction
1.1 Preface
This manual describes the entire HSA3500 and HSA3500 plus power supply manufac-
tured by SPECS. For all common features we will use the term ”HSA” for both. When it
is necessary to point out specific features, we will use the terms HSA3500 and HSA3500
plus, respectively.
1.2 General Information
With the HSA 3500 plus SPECS presents a new versatile high voltage power supply for
electrostatic field applications. The HSA3500 plus is the further development of
HSA3500. The modular design of the unit allows independent setting of all voltages -
no voltage dividers are used.
Each module is fully galvanically floating, highly stable and linear. The voltages are con-
trolled by high-precision 24-bit digital-to analog converters with an overall maximum
settle time of 3 ms.
The HSA consists of a main CPU and various voltage and current modules. All commu-
nication goes over the CAN -Bus to the main CPU. The main CPU distributes all CAN -
Bus messages to respective modules. The device pr5V, +15V for the modules
and main CPU, and +24V for external devices via CAN-Bus (e.g. EC10). On the back pan-
el you connect all the hardware to the analyzer (e.g. SPECS Phoibos) and detector (e.g.
