1.Introduction
This chapter describes the general characteristics and main features of the
Polarity Inverters WPOLINV200XA, WPOLINV400XA and WPOLINV600XA.
1.1 Polarity Inverter Overview
Extreme reliability and easiness of configuration and maintenance are the key
features of these polarity inverters.
These polarity inverters are able to reverse currents up to 630 A and so they
represent the perfect fit for the CAEN ELS NGPS unipolar power supplies, both in single
or paralleled configurations.
Each polarity inverter fits in a single 19”6U crate and it can be controlled via
dry contacts while providing to the user information about the correct working of the
system and the selected polarity.
Figure 1: Schematic of the unit.
Polarity inversion is achieved with a linear motor acting as commutator, this
avoiding any possible problem even in case of e.g. black out –which represents an
issue if inversion is obtained via relays-based commutators.
Figure 1 represents the schematic operation of the unit. A linear motor is
responsible for the polarity switching, e.g. in Figure 1 the selected polarity is reversed.

These polarity inverters have the following ratings listed in Table 1:

WPOLINV600XA
630 A Polarity Inverter

Table 1: Main ratings of the polarity inverters.
If the rear power connections of the Polarity Inverter are
accessible, IN and OUT connections result in HAZARDOUS
LIVE parts and must be isolated or confined following local
regulations.
If the Maximum Voltage level is below 70 VDC further
isolations are not required.
All these polarity inverters are already supplied with the signal cable that allows
connecting them directly to an NGPS power supply.
