1 INTRODUCTION TO THE ZAPI-MOS FAMILY
The ZAPIMOS chopper family represents ZAPI’s answer to the needs of the 90’s.
To ensure that products remain on the market, without running the risk of becoming
technically obsolescent, the ZAPIMOS family offers the following features:
- Advanced technology.
- Economical costs.
- Maximum safety.
- Maximum flexibility.
- Open to future technical innovations.
- Optimum level of protection.
The design has been derived from:
- High Frequency Mos Technology .
- Real time control over the internal and external components that influence the
behavior of the machine, with self diagnosis of the checking circuits themselves.
- Stored Program Machine (SPC), where the hardware is completely separate from
the functions to be configured. The programme is parametric and can easily be
modified by the end user.
- Various chopper configurations can be selected by the user, without the need for
hardware modifications.
- Future technological updates are made easy for the user.
The communication protocol will continue to evolve, thereby offering increas-
ing possibilities of interaction and expansion. For this reason, the Zapimos
family offers a standard dialogue mode with external systems. This allows
interfacing with
commercially available machines. Zapi can offer a range of individually designed
Console Software with various features and prices.
- SEM 2 meets the requirements of (IP54). This provides excellent protection against
spray (water, acid.), and against the ingress of dust or small foreign particles.
Access to the control logic is very simple, and allows simple substitution or replace-
ment.
- The SEM2 family of Choppers are suitable for operating on DC voltages from 24 to
48V inclusive, with maximum armature current up to 350A.
The choppers may be used to control DC Separately Excited Motors with power
ratings up to 5.5kW.
