1 INTRODUCTION TO THE ZAPIMOS FAMILY
The ZAPIMOS chopper family is ZAPI’s answer to the needs of users of the ’90s.
To ensure that the product stays on the market without running the risk of becoming
technologically obsolete, ZAPI has designed the ZAPIMOS family to offer the following
features:
- Advanced technology and economical costs
- Maximum safety
- Maximum flexibility
- Open to future technological innovations
- Optimum level of protection.
This implies:
- High frequency Mos technology
- Real-time control over the internal and external parts that can influence the behav-
iour of the machine, with self-diagnosis of the checking circuits themselves.
- Stored programme machine (SPC) where the hardware is completely separate from
the functions to be configured. The programme is parametric and can also be modi-
fied by the final user.
- Various chopper functional configurations can be selected by the user, without the
need for hardware modifications.
- Any future technological updates are made clear to the user.
The communication protocol will continue to evolve, thus offering increasing possibili-
ties of interaction.
For this reason, the ZAPIMOS family offers a standard dialogue mode with external
systems, for easy interfacing with commercially available machines. ZAPI offers a
range of programming consoles with various features and prices.
- Logic and power units are fitted in a sealed container (IP54), to guarantee protection
against splashes (water, acid, etc.) and dust, chips, or small particles.
Access to the logic for replacement or checks, however, is very easy.
- The H2B chopper is the top-of-the-line model of the Zapimos family. It is suitable for
operating at voltages from 24 to 96 V with maximum currents of 400 or 600 amp.
Suitable for use with series motors with powers from 2000 W to 15 kW.
