1. Introduction

This instruction manual (P/N 6005-962) contains information on the installation, operation, calibration
and maintenance of the model 2253i and model 2253iX AC power sources.

Figure 1-1: Model 2253iX AC Source.

1.1 General Description

The Compact i/iX Series of AC Power Source is a family of high efficiency, rack mountable, AC Power
Sources that provide a precisely controlled output voltage with low distortion and measurements. In
addition, the unit provides measurements of voltage and current, and the iX models offer extensive
power analyzer capabilities with easy to use interface software. Standard output voltage ranges are
150 Vac and 300 Vac RMS. The 2253i/iX models operate in three-phase mode and provide a
maximum output power of 750VA per phase. A –MODE option is available which parallels all three
outputs in a single-phase mode of operation. A unique constant power mode allows for higher output
current at less than full-scale voltage effectively increasing the usability for many applications where
otherwise a higher power level AC source may be needed.

Read the installation instructions carefully before attempting to install and operate the Compact i/iX
Series power source.
